• An anti-virus that is in fact a virus and called "virus"!

  While my father was reading a newspaper site he opened an article for a piece of news, and it seems that a Trojan horse is entered with the page. Oddly for me, an antiviruswas downloaded and installed and then automatically activates. Then the virus started working and it refuses to open the driver of operating "C:\". "normally by clicking on it and it offers my father whenever the full Version that the trial version is a job. And when my Dad tried to uninstall "C:\". "when he was able to open it, the filr did not contain an uninstall file for it ("for sure it's a virus') and then try to delete from (add or remove programs, he took, but it did not!.) And enter the "C:\". ", try to delete the file, it did not and trying to delete every file inside one at a time some has been removed and some have refused to. And the computer is taken over by this thing and the name is "Antivirus" and apearing as a.

  I hope someone can help and thank you.

  The more fast, effective and safe method for the cleaning of these infections is with a Linux based rescue CD. You will need to download an ISO, burn it to a CD, configure the system to boot from the firstCD/DVD drive and then boot the system with the CD so that the hard disk is not Active.
  If you choose to go this route, see - Kaspersky Rescue Disk 10
  The articles on this page will show you exactly what to do.

  Or, you could try to start the computer in Mode safe mode and see if the system restore can successfully restore the system to just before he became infected.
  If you are more comfortable as well, see - How to restore Windows XP to a previous state
  Choose a restore point created at least 2 days before the date that the system become compromised.
  (If the system cannot boot safe mode, see if it can be started in safe mode with command prompt )

• I need anti virus?

  Hi guys, anyone would be able to recommend anti Virus app? By mistake I installed Norton who caused major problems with my machine ~ event if it's the mac version. Its now uninstalled, but with safety in mind, do I have to have anti virus? I thank in advance

  Mac users often ask if they should install "anti-virus" (AV) or software "anti-malware". The answer is 'no', but it can give the false impression that there is no threat of what is loosely called 'virus '. There is a threat.

  1. it is a comment on what you should - and should not-do to protect you from malicious software ("malware") that runs on the Internet and gets onto a computer as an unintended consequence of the user's actions.

  It does not apply to the software, such as keyloggers, which can be installed deliberately by an intruder who has convenient access to the computer, or who has been able to take control of it remotely. This threat is in a different category, and there is no easy way to defend against it. AV software is not intended to and does not, to defend against these attacks.

  The comment is long because the issue is complex. The essential points are in articles 5 and 11.

  OS X implements now three levels of integrated protection specifically against malware, not to mention the protections of runtime such as quarantine the file, execute disable, sandbox, protecting the integrity of system, System Library randomization and randomized address space layout , which can also prevent other kinds of exploits.

  2. all versions of Mac OS X 10.6.7 were able to detect the malware Mac known in downloaded files and block non-secure web plugins. This feature is transparent to the user. Apple calls internally it "XProtect."

  The malware used by XProtect recognition database is automatically updated. However, you should not count on it, because the attackers are still at least a day before the defenders.

  The following restrictions apply to XProtect:

  ☞ circumvented by some third-party network software, such as the BitTorrent clients and Java applets.

  ☞ It applies only to software downloaded on the network. Software installed from a CD or other media is not verified.

  As new versions of Mac OS X are available, it is not clear whether Apple will continue indefinitely maintain the older versions such as 10.6 XProtect database. Versions of obsolete systems security may eventually be affected. Updates to security for the code of obsolete systems will be stop being released at any given time, and which can leave them open to other types of attack in addition to malware.

  3. starting with the OS X 10.7.5, there was a second layer of built-in malware protection, designated "Gatekeeper" by Apple. By default, applications and installation packages downloaded from the network will be run only if they are digitally signed by a developer to a certificate issued by Apple. Certified software in this way has not been checked for safety by Apple, unless it comes to the App Store, but you can be reasonably sure that it has not been changed by someone other than the developer. His identity is known to Apple, so it could be held legally responsible if it distributes malicious software. Which may not mean much if the developer lives in a country with a weak legal system (see below).

  Access controller does not depend on a database of known malware. He has, however, the same limitations as XProtect and in addition the following:

  ☞ It can easily be turned off or overridden by the user.

  ☞ A malware attacker could find a way around it, or could take control of a certificate of signing of code under false pretenses or could simply ignore the consequences of the distribution of malware Tryggvason.

  ☞ Developer App store could find a way around the Apple control, or the control may fail due to human error.

  Apple took too long to revoke some known attackers codesigning certificates, thus diluting the value of the keeper and the program developer ID. These variances do not involve the App Store products, however.

  For the reasons given, App Store, and, to a lesser extent - other applications recognized by signed Gatekeeper, are safer than others, but they cannot be considered to be absolutely sure. "Sand" applications could make to access to private data, such as your contacts, or for access to the network. Think that before granting access. Security sandbox is based on user input. Never click through any application for leave without thinking.

  4. by starting with OS X 10.8.3, a third layer of protection has been added: a "Malware Removal Tool" (MRT). MRT runs automatically in the background. He checks and removes, malware that corresponds to a database of recognition held by Apple. To ensure that MRT will be executed when the database is updated, the App Store tab in system preferences and check the box marked

  Install the system data files and security updates

  If it is not already done.

  As XProtect, MRT is effective against known threats, but not against strangers. It alerts you if it detects malware, but otherwise, it has no user interface.

  5. the built-in Mac OS x security features reduce the risk of malware attack, but they are not and will never be complete protection. Malware is a problem of human behavior, not a behavior machine, and none only of technological solution will solve. Software protect you from trust only will make you more vulnerable.

  The best defense is always going to be your own intelligence. Except perhaps feats of Java, all the known malware, circulating on the Internet wearing reached a completely setting installation to update to OS X 10.6 or later takes the form of so-called "Trojans", which may have no effect if the victim is deceived in their execution. The threat thus amounts to a battle of wits between you and cybercriminals. If you are better informed, they think you are, you win. In effect, it means that you always stay in the shelter of practical computing. How do you know when you leave the safe harbor? Here are a few signs warning of danger.

  Software from a reliable source

  ☞ Software with a brand, such as Adobe Flash Player, does not come directly from the Web site. Don't be fooled an alert of any website for updating Flash, or your browser, or other software. A real alert that Flash is outdated and blocked is shown on this support page. In this case, follow the instructions on the support page. Furthermore, assume that the alert is false and that someone is trying to rip you off to install malicious software. If you see these alerts on more than one Web site, ask for instructions.

  ☞ Software any is distributed via BitTorrent or Usenet, or on a Web site that distributes pirated music and movies.

  ☞ Rogue sites Web such as CNET Download MacUpdate, Soft32, Softonic and SourceForge distribute free applications that have been packaged in a superfluous "install".

  ☞ The software is advertised through spam or intrusive web ads. Any announcement, on any site, which includes a direct link to a download should be ignored.

  Software that is clearly illegal or doing something illegal

  Commercial software ☞ high-end such as Photoshop is "cracked" or "free."

  ☞ An application helps you violates copyright law, for example to circumvent the copy protection on a commercial software, or streamed media recording to be reused without permission. All the 'YouTube downloaders' are in this category, but not all are necessarily malicious.

  Conditional or unsolicited offer from strangers

  ☞ A phone calling or a web page you indicates that you have a "virus" and offers to remove. (Some reputable sites warned visitors who have been infected with the malware "DNSChanger" legitimately. The exception to this rule applies.)

  ☞ A web site offers a free content like music or video, but for use, you must install a "codec", 'plug-in', 'player' 'Downloader', 'extractor', or 'certificate' which comes from the same site, or a stranger.

  ☞ You win a prize in a competition that you are never entered.

  ☞ someone on a forum like this is eager to help you, but only if you download an application of your choice.

  ☞ a 'FREE WI - FI!' network presents itself in a public place like an airport, but is not provided by management.

  ☞ Online everything that you expect to pay is 'free '.

  Unexpected events

  ☞ a file is downloaded automatically when you visit a web page, without any further action on your part. delete any file without opening it.

  ☞ You open what you think, it is a document and you receive an alert that it is "an application downloaded from the Internet." Click Cancel and delete the file. Even if you don't get the alert, you must always remove any download that is not what you expected it to be.

  ☞ An application does something you don't expect, such as permission to access your contacts, your location or the Internet without obvious reason.

  ☞ Software is attached to the email you na not ask, even if it is (or seems to come) by a person of trust.

  I do not leave the safe harbour that once will necessarily lead to disasters, but make a habit of it will weaken your defenses against malicious software attacks. None of the above scenarios must, at the very least, make you uncomfortable.

  6. Java on the Web (not to be confused with JavaScript, to which it is not related, despite the similarity of names) is a weak point in the security of any system. Java is, among other things, a platform to run complex applications in a web page. That was always a bad idea, and Java developers have proved unable to apply it without also creating a portal for malware to enter. Past Java exploits are the closest thing there has ever been a type virus Windows affecting OS X. simply load a page with Java malicious content could be harmful.

  Fortunately, client-side Java on the Web is outdated and largely disappeared. Only a few outdated sites still use it. Try to accelerate the process of extinction by avoiding these sites, if you have a choice. Forget to play games or other uses not Java essentials.

  Java is not included in OS X 10.7 and later versions. Discrete Java installers are distributed by Apple and Oracle (the developer of Java). Do not use one unless you need it. Most of the people don't. If Java is installed, turn it off- not the JavaScript in your browser.

  Whatever the version, experience has shown that Java on the Web is not reliable. If you must use a Java applet for a job on a specific site, Enable Java only for the site in Safari. Never activate Java for a public Web site that carries the third-party advertising. Use only on websites that are well known, protected by login and secure without ads. In Safari 6 or later, you will see a padlock icon in the address bar when you visit a secure site.

  7. another perennial weak point is Adobe Flash Player. Like Java, Flash is declining well deserved, but content Flash is still much more widespread than the contents of Java on the Web. If you choose to install the Flash plugin, you can reduce your exposure to Flash by checking the box marked

  Stop the plug-ins to save energy

  in the Advanced tab of the preferences of Safari window, if not already done. Consider also installing an extension Safari as "ClickToFlash" or "ClickToPlugin." They will prevent the Flash content automatically load and are initially not Flash video is substituted for Flash on YouTube and perhaps a few other sites. I tested the extensions and found them safe, but you should always do your own research before you decide whether to trust any third party software.

  8. remain within the sphere of security, and you will be as safe from malware you can be practically. The rest of this comment is what you must do to protect you.

  Never install any AV or products 'Internet security' for Mac if you have a choice, because they are all worse than useless. If you are required by a (wrong) institutional policy to install some kind of AV, choose one of the free apps in the Mac App Store, nothing else.

  Why you should not use products AV?

  ☞ To recognize malware, software depends on a database of known threats, which is always at least one day to day. This technique is a proven failure, as a major supplier of AV software has admitted. Most of the attacks are "zero-day" - that is, previously unknown. Recognition-based AV does not defend against such attacks, and the enterprise IT industry comes to realize that the traditional AV software is worthless.

  ☞ design is based generally on the nonexistent threat that malware can be injected at any time, anywhere in the file system. Malware is downloaded from the network; He is not of the blue leaves. To meet this threat does not exist, a commercial AV software changes or low level functions of the operating system, which is a waste of resources and a frequent cause of instability, bugs, poor performance, and duplicates.

  ☞ changing the operating system, the software can also create weaknessesthat could be exploited by malicious attackers.

  ☞ especially, a false sense of security is dangerous. This fact relates to all AV software it will never be any changes elsewhere.

  9. a free AV product from the Mac App Store is safe as long as you don't let it delete or move files. Ignore all the warnings that it can give you on "heuristic" or "phishing." These warnings, if they are not simply false positives, see the text of e-mail messages or updates cached web pages, not malware.

  An AV application is not necessary and may not be invoked for protection against malware for OS X. It is useful, or even not at all, only to detect malware Windows and even for this use it is not really effective, because the new Windows malware makes its appearance much faster than OS X malware.

  Windows malware cannot hurt you directly (unless, of course, you use Windows). Just do not pass to someone else. A malicious link in the e-mail is usually easy to recognize by the name alone. A concrete example:

       London Terror Moovie.avi [124 spaces] Checked By Norton Antivirus.exe

  You don't need software to tell you it's a horse Trojan for Windows. Software may be able to tell what trojan is, but who cares? In practice, there is no reason to use a recognition software, unless an organizational strategy requires. Malware Windows is so widespread that you must assume that it is in each attachment until proof to the contrary. Nevertheless, a free AV product on the App Store can serve a purpose if it fulfills a misinformed network administrator that says you must have some sort of application AV. An App Store product will not change the operating system; in fact, it does nothing, unless you run it.

  If you are just curious to know if a file is considered malware by the AV engines, you can download it from the "VirusTotal" site, where it will be tested against most of them without charge. A negative result is evidence of what whether, for the reasons given above. I do not recommend doing this with a file that may contain private information.

  10. There seems to be a common belief that the firewall Application acts as a barrier to infection, or prevents operation of malware. He does not. It blocks incoming connections to some network services you are using, such as file sharing. It is disabled by default, and you should leave it like that if you're behind a router on a private home or office network. Activate only when you are on an untrusted network, for example a public Wi - Fi hotspot, where you do not want to provide services. Disable services that you don't use in the sharing preferences window. All are disabled by default.

  11. as a Mac user, you don't have to live in fear that your computer may be infected whenever you install the software, read emails, or visit a web page. But nor can you assume that you will always be free from exploitation, no matter what you do. Internet browsing, it's like walking the streets of a big city. It can be as safe or as dangerous that you choose to do so. The greatest harm done by software AV is precisely its selling point: it makes people feel safe. They can then feel sufficiently safe to take risks, which the software does not protect them. Nothing can reduce the need for safe computing practices.

• affected by the virus cannot get email to work

  MacBook Pro with Airport Extreme - I was hit by a virus (I know weird, right?) and McAfee to get rid of it.  However, now I can't my email to work by Mail or Thunderbird.  I was on the phone with Wowway everyday, we will change the passwords for each account and then it will work again for a few hours.  I think the problem is always with Wowway but they say I still have a virus.  I used McAfee twice more, and he says he has none are detected.  I keep getting the status of invalid login or password when I try to access my emails.  Suggestions?  Should I take the MacBook for the genius bar or continue to fight with Wowway?  Any ideas at all?  Thank you very much!

  If you take your Mac to the genius Bar, they will tell you the same thing, that we will tell you. UN-modified Mac OS X does not in this way.

  You will need to remove all of your changes before they will even look at it.

  There is no known MAC viruses, despite the fact that junk as McAfee will bring tons of things she called virus. It is quite possible that it had removed parts of Mac OS X, you might also need to re - install.

  So called "anti-virus" scanners are not useful on the Mac, because they interfere with the Apple has already provided the integrated protection.

• Virus Malware Trojans and other junk

  Okay, so, it is true that I am not a Mac person, gasp, but here comes a true unbiased.

  I helped a member of the family rebuild a MacBook Pro using a USB stick to boot and install the latest version of El Capitan.  I was helping to restore the data literally 48 hours later and to my surprise, that the machine was infected with two pieces of malware (which was visible) 'Advanced Mac Cleaner' and 'ZipClould '.  It is interesting ZipCloud himself had placed in the dock bar, replacing a similar looking cloud storage service.

  So clearly the machine has been compromised, and it was easier to rebuild than to go on the road to 'cleaning up' at this stage.

  How can I avoid this happening again?  I can't look over the shoulder 24 x 7, but there should be a way to avoid this.

  11. as a Mac user, you don't have to live in fear that your computer may be infected whenever you install the software, read emails, or visit a web page. But nor can you assume that you will always be free from exploitation, no matter what you do. Internet browsing, it's like walking the streets of a big city. It can be as safe or as dangerous that you choose to do so. The greatest harm done by software AV is precisely its selling point: it makes people feel safe. They can then feel sufficiently safe to take risks, which the software does not protect them. Nothing can reduce the need for safe computing practices.

• HOW YOU REPALCE THE WINDOWS operating system (Vista) YOU LOST IN THE REMOVAL of a VIRUS?

  I contracted a virus called viruses 'The FBI'. When removing this virus, I lost my OS (WINDOWS VISTA), I was eager to replace it. I don't have the original product key.  I would also like to know if I could tell her, Windos XP or Windows 7 upgrade? Thank you for your quick response and aaccurate.

  Hello

  XP is not an upgrade, and you can buy XP or Windows 7.

  XP is no longer marketed by Microsoft or main computer for many years manufacturers.

  There are several methods to reinstall Vista.

  There is no Windows Vista downloads available from Microsoft.

  You can contact your computer manufacturer and ask them to send you a set of recovery disks.

  They should do this for a small fee.

  To reinstall Vista using their recovery disk/s, you start from the 1st recovery disk they provide and follow the manufacturer's instructions to reinstall:

  You need to change the Boot order to make the DVD/CD drive 1st in the boot order:

  How to change the Boot order in BIOS:

  http://pcsupport.about.com/od/fixtheproblem/SS/bootorderchange.htm

  "How to replace Microsoft software or hardware, order service packs and replace product manuals.

  http://support.Microsoft.com/kb/326246

  And if you have never received a recovery disk when you bought your computer, there should be a recovery Partition on the hard drive to reinstall Vista on how you purchased your computer.

  The recovery process can be started by pressing a particular combination of the key or keys at startup. (Power on / start)

  Maybe it's F10, F11, Alt + F10, etc., depending on the manufacturer.

  Ask them to the proper key sequence.

  And if you do not score a manufacturer of recovery on your hard drive, you should be able to make your own recovery from her disks to reinstall the operating system.

  Go to programs > name of the manufacturer of your computer > then their system or recovery tools software topics for them, depending on how it is formulated.

  If you can't find any reference to it, contact the manufacturer for advice on how to make these recovery disks.

  Some manufacturers have more available Vista recovery disks.

  If this happens, you may need to try this instead:

  You can also borrow and use a Microsoft Vista DVD, which contains the files for the different editions of Vista (Home Basic, Home Premium, Business and Ultimate) must be installed. The product key on your computer / Laptop box determines what Edition is installed.

  Other manufacturers recovery DVDs are should not be used for this purpose.

  And you need to know the version of 'bit' for Vista, as 32-bit and 64-bit editions come on different DVDs

  Here's how to do a clean install of Vista using a DVD of Vista from Microsoft:

  "How to do a clean install and configure with a full Version of Vista '

  http://www.Vistax64.com/tutorials/117366-clean-install-full-version-Vista.html

  And once the operating system is installed, go to your computer manufacturer's website and get the latest drivers for your particular model or laptop computer.

  And phone Activation may be necessary when you use the above installation method.

  "How to activate Vista normally and by Activation of the phone '

  http://www.Vistax64.com/tutorials/84488-activate-Vista-phone.html

  @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

  Go to your computer / computer laptop manufacturer Web site and see if Windows 7 drivers are available for your make and model computer / laptop.

  If this is not available, Windows 7 will not properly work for you.

  Run the "Windows 7 Upgrade Advisor.

  http://www.Microsoft.com/en-US/Download/details.aspx?ID=20

  Check if your specifications are compatible for Windows 7:

  "Windows 7 system requirements"

• Lightroom develop settings disappeared after a computer virus removal

  Hi all

  I have a problem with my development settings to find Lr I had problem with virus a couple days where all my files have been encrypted. A so-called virus ransomeware RSA 4096 caused it. They have (support antivirus Norton) has removed the virus for me but they told me that it was nothing I could do with my files photo on my hard drive of the computer. The result was that I had to delete all the files that I had stored. Luckely, I made a back-up, 2 days before (on my external hard drive), my computer has been infected. The problem is, when I try to use my backup catalog I can't access my development settings in images. Everything is zero. RAW file is in place and I can start to change the image of course again, but it's a lot of work. The other strange thing is that all of my files exported JPG also appears in the catalog and I don't really know why... Maybe I'm an amateur, but I would like help, because it frustrates me :-(

  Best wishes

  Ken

  Could you try to open the other catalogs (recent) backup of your external drive.

  It is possible that the virus has infected the backup too.

  Find your external drive for catalogs. Search for "*.lrcat " and see if it returns multiple catalogs.

  You can also see recover the catalog and images after resetting preferences in Adobe Photoshop Lightroom

  I use the latest Version of Lr, 5.6

  Latest version of Lightroom 5 is 5.7.1.  See the maintenance of Lightroom

• Firefox is infected. How to clean it?

  I System Security 2012, and I have a LOT of problems with it, just recently started today, which was so annoying now. Everything that I try to run it says that it is infected, and it tells me I have what is called Zeus trying to steal important information on my computer.

  Now he says Firefox is infected and cannot work. It shows that it is running, but it disappeared from my screen.

  I also advocate for the window, and it says that my computer is fine. While the center of the system security sends me things that we called 'Virus Trojan horse '.

  So, how can I get Firefox to run again? Whenever I click on a program it says that it is infected.

  http://malwaretips.com/thread-system-security-2012-removal-instructions-uninstall-Guide

  Security system 2012 is a fake system security software which is considered to be unreliable.
  
  Thieves are malicious programs that use cyber criminals to trick users by displaying a false threats and problems it claims to have detected. In fact, none of the issues are real and are used to convince the user into buying their software and the theft of their personal financial information.

  Mac users often ask if they should install "anti-virus" (AV) or software "anti-malware". The answer is 'no', but it can give the false impression that there is no threat of what is loosely called 'virus '. There is a threat.

  1. it is a comment on what you should - and should not-do to protect you from malicious software ("malware") that runs on the Internet and gets onto a computer as an unintended consequence of the user's actions.

  It does not apply to the software, such as keyloggers, which can be installed deliberately by an intruder who has convenient access to the computer, or who has been able to take control of it remotely. This threat is in a different category, and there is no easy way to defend against it. AV software is not intended to and does not, to defend against these attacks.

  The comment is long because the issue is complex. The essential points are in articles 5 and 11.

  OS X implements now three levels of integrated protection specifically against malware, not to mention the protections of runtime such as quarantine the file, execute disable, sandbox, protecting the integrity of system, System Library randomization and randomized address space layout , which can also prevent other kinds of exploits.

  2. all versions of Mac OS X 10.6.7 were able to detect the malware Mac known in downloaded files and block non-secure web plugins. This feature is transparent to the user. Apple calls internally it "XProtect."

  The malware used by XProtect recognition database is automatically updated. However, you should not count on it, because the attackers are still at least a day before the defenders.

  The following restrictions apply to XProtect:

  ☞ circumvented by some third-party network software, such as the BitTorrent clients and Java applets.

  ☞ It applies only to software downloaded on the network. Software installed from a CD or other media is not verified.

  As new versions of Mac OS X are available, it is not clear whether Apple will continue indefinitely maintain the older versions such as 10.6 XProtect database. Versions of obsolete systems security may eventually be affected. Updates to security for the code of obsolete systems will be stop being released at any given time, and which can leave them open to other types of attack in addition to malware.

  3. starting with the OS X 10.7.5, there was a second layer of built-in malware protection, designated "Gatekeeper" by Apple. By default, applications and installation packages downloaded from the network will be run only if they are digitally signed by a developer to a certificate issued by Apple. Certified software in this way has not been checked for safety by Apple, unless it comes to the App Store, but you can be reasonably sure that it has not been changed by someone other than the developer. His identity is known to Apple, so it could be held legally responsible if it distributes malicious software. Which may not mean much if the developer lives in a country with a weak legal system (see below).

  Access controller does not depend on a database of known malware. He has, however, the same limitations as XProtect and in addition the following:

  ☞ It can easily be turned off or overridden by the user.

  ☞ A malware attacker could find a way around it, or could take control of a certificate of signing of code under false pretenses or could simply ignore the consequences of the distribution of malware Tryggvason.

  ☞ Developer App store could find a way around the Apple control, or the control may fail due to human error.

  Apple took too long to revoke some known attackers codesigning certificates, thus diluting the value of the keeper and the program developer ID. These variances do not involve the App Store products, however.

  For the reasons given, App Store, and, to a lesser extent - other applications recognized by signed Gatekeeper, are safer than others, but they cannot be considered to be absolutely sure. "Sand" applications could make to access to private data, such as your contacts, or for access to the network. Think that before granting access. Security sandbox is based on user input. Never click through any application for leave without thinking.

  4. by starting with OS X 10.8.3, a third layer of protection has been added: a "Malware Removal Tool" (MRT). MRT runs automatically in the background. He checks and removes, malware that corresponds to a database of recognition held by Apple. To ensure that MRT will be executed when the database is updated, the App Store tab in system preferences and check the box marked

  Install the system data files and security updates

  If it is not already done.

  As XProtect, MRT is effective against known threats, but not against strangers. It alerts you if it detects malware, but otherwise, it has no user interface.

  5. the built-in Mac OS x security features reduce the risk of malware attack, but they are not and will never be complete protection. Malware is a problem of human behavior, not a behavior machine, and none only of technological solution will solve. Software protect you from trust only will make you more vulnerable.

  The best defense is always going to be your own intelligence. Except perhaps feats of Java, all the known malware, circulating on the Internet wearing reached a completely setting installation to update to OS X 10.6 or later takes the form of so-called "Trojans", which may have no effect if the victim is deceived in their execution. The threat thus amounts to a battle of wits between you and cybercriminals. If you are better informed, they think you are, you win. In effect, it means that you always stay in the shelter of practical computing. How do you know when you leave the safe harbor? Here are a few signs warning of danger.

  Software from a reliable source

  ☞ Software with a brand, such as Adobe Flash Player, does not come directly from the Web site. Don't be fooled an alert of any website for updating Flash, or your browser, or other software. A real alert that Flash is outdated and blocked is shown on this support page. In this case, follow the instructions on the support page. Furthermore, assume that the alert is false and that someone is trying to rip you off to install malicious software. If you see these alerts on more than one Web site, ask for instructions.

  ☞ Software any is distributed via BitTorrent or Usenet, or on a Web site that distributes pirated music and movies.

  ☞ Rogue sites Web such as CNET Download MacUpdate, Soft32, Softonic and SourceForge distribute free applications that have been packaged in a superfluous "install".

  ☞ The software is advertised through spam or intrusive web ads. Any announcement, on any site, which includes a direct link to a download should be ignored.

  Software that is clearly illegal or doing something illegal

  Commercial software ☞ high-end such as Photoshop is "cracked" or "free."

  ☞ An application helps you violates copyright law, for example to circumvent the copy protection on a commercial software, or streamed media recording to be reused without permission. All the 'YouTube downloaders' are in this category, but not all are necessarily malicious.

  Conditional or unsolicited offer from strangers

  ☞ A phone calling or a web page you indicates that you have a "virus" and offers to remove. (Some reputable sites warned visitors who have been infected with the malware "DNSChanger" legitimately. The exception to this rule applies.)

  ☞ A web site offers a free content like music or video, but for use, you must install a "codec", 'plug-in', 'player' 'Downloader', 'extractor', or 'certificate' which comes from the same site, or a stranger.

  ☞ You win a prize in a competition that you are never entered.

  ☞ someone on a forum like this is eager to help you, but only if you download an application of your choice.

  ☞ a 'FREE WI - FI!' network presents itself in a public place like an airport, but is not provided by management.

  ☞ Online everything that you expect to pay is 'free '.

  Unexpected events

  ☞ a file is downloaded automatically when you visit a web page, without any further action on your part. delete any file without opening it.

  ☞ You open what you think, it is a document and you receive an alert that it is "an application downloaded from the Internet." Click Cancel and delete the file. Even if you don't get the alert, you must always remove any download that is not what you expected it to be.

  ☞ An application does something you don't expect, such as permission to access your contacts, your location or the Internet without obvious reason.

  ☞ Software is attached to the email you na not ask, even if it is (or seems to come) by a person of trust.

  I do not leave the safe harbour that once will necessarily lead to disasters, but make a habit of it will weaken your defenses against malicious software attacks. None of the above scenarios must, at the very least, make you uncomfortable.

  The emergence of data "ransomware" for Mac was part of the defense against the attacks of backup all data. Since an infected machine could destroy its own backups, at least a backup unit must always be in offline mode. For example, you could turn your backup drives, keeping one with you or another site. This strategy also protects against a physical threat such as a fire or theft.

  6. Java on the Web (not to be confused with JavaScript, to which it is not related, despite the similarity of names) is a weak point in the security of any system. Java is, among other things, a platform to run complex applications in a web page. That was always a bad idea, and Java developers have proved unable to apply it without also creating a portal for malware to enter. Past Java exploits are the closest thing there has ever been a type virus Windows affecting OS X. simply load a page with Java malicious content could be harmful.

  Fortunately, client-side Java on the Web is outdated and largely disappeared. Only a few outdated sites still use it. Try to accelerate the process of extinction by avoiding these sites, if you have a choice. Forget to play games or other uses not Java essentials.

  Java is not included in OS X 10.7 and later versions. Discrete Java installers are distributed by Apple and Oracle (the developer of Java). Do not use one unless you need it. Most of the people don't. If Java is installed, turn it off- not the JavaScript in your browser.

  Whatever the version, experience has shown that Java on the Web is not reliable. If you must use a Java applet for a job on a specific site, Enable Java only for the site in Safari. Never activate Java for a public Web site that carries the third-party advertising. Use only on websites that are well known, protected by login and secure without ads. In Safari 6 or later, you will see a padlock icon in the address bar when you visit a secure site.

  7. another perennial weak point is Adobe Flash Player. Like Java, Flash is declining well deserved, but content Flash is still much more widespread than the contents of Java on the Web. If you choose to install the Flash plugin, you can reduce your exposure to Flash by checking the box marked

  Stop the plug-ins to save energy

  in the Advanced tab of the preferences of Safari window, if not already done. Consider also installing an extension Safari as "ClickToFlash" or "ClickToPlugin." They will prevent the Flash content automatically load and are initially not Flash video is substituted for Flash on YouTube and perhaps a few other sites. I tested the extensions and found them safe, but you should always do your own research before you decide whether to trust any third party software.

  8. remain within the sphere of security, and you will be as safe from malware you can be practically. The rest of this comment is what you must do to protect you.

  Although it may seem counterintuitive, you should never install any AV or products 'Internet security' for Mac if you have a choice, because they are all worse than useless. If you are required by a (wrong) institutional policy to install some kind of AV, choose one of the free apps in the Mac App Store, nothing else.

  Why you should not use products AV?

  ☞ To recognize malware, software depends on a database of known threats, which is always at least one day to day. This technique is a proven failure, as a major supplier of AV software has admitted. Most of the attacks are "zero-day" - that is, previously unknown. Recognition-based AV does not defend against such attacks, and the enterprise IT industry comes to realize that the traditional AV software is worthless.

  ☞ design is based generally on the nonexistent threat that malware can be injected at any time, anywhere in the file system. Malware is downloaded from the network; He is not of the blue leaves. To meet this threat does not exist, a commercial AV software changes or low level functions of the operating system, which is a waste of resources and a frequent cause of instability, bugs, poor performance, and duplicates.

  ☞ changing the operating system, the software can also create weaknessesthat could be exploited by malicious attackers.

  ☞ especially, a false sense of security is dangerous. This fact relates to all AV software it will never be any changes elsewhere.

  Using the software AV defines you for double exploitation: by hackers, malicious software, that the software does not protect you and the actual AV industry. The latter will often try to hang with a product free of appeal , so it can charge you for "improvements" later.

  9. a free AV product from the Mac App Store is safe as long as you don't let it delete or move files. Ignore all the warnings that it can give you on "heuristic" or "phishing." These warnings, if they are not simply false positives, see the text of e-mail messages or updates cached web pages, not malware. Also ignore any attempt to upsell you to a paid version of the product.

  An AV application is not necessary and may not be invoked for protection against malware for OS X. It is useful, or even not at all, only to detect malware Windows and even for this use it is not really effective, because the new Windows malware makes its appearance much faster than OS X malware.

  Windows malware cannot hurt you directly (unless, of course, you use Windows). Just do not pass to someone else. A malicious link in the e-mail is usually easy to recognize by the name alone. A concrete example:

       London Terror Moovie.avi [124 spaces] Checked By Norton Antivirus.exe

  You don't need software to tell you it's a horse Trojan for Windows. Software may be able to tell what trojan is, but who cares? In practice, there is no reason to use a recognition software, unless an organizational strategy requires. Malware Windows is so widespread that you must assume that it is in each attachment until proof to the contrary.

  A free AV product on the App Store can serve a purpose if it fulfills a misinformed network administrator that requires to have some sort of application AV. An App Store product will not change the operating system; in fact, it does nothing, unless you run it.

  If you are just curious to know if a file is recognized as malware by the AV engines, you can download it from the "VirusTotal" site, where it will be tested against most of them. A negative result is evidence of what whether, for the reasons given above. I do not recommend doing this with a file that may contain private information.

  10. There seems to be a common belief that the firewall Application acts as a barrier to infection, or prevents operation of malware. He does not. It blocks incoming connections to some network services you are using, such as file sharing. It is disabled by default, and you should leave it like that if you're behind a router on a private home or office network. Activate only when you are on an untrusted network, for example a public Wi - Fi hotspot, where you do not want to provide services. Disable services that you don't use in the sharing preferences window. All are disabled by default.

  11. as a Mac user, you don't have to live in fear that your computer may be infected whenever you install the software, read emails, or visit a web page. But nor can you assume that you will always be free from exploitation, no matter what you do. Internet browsing, it's like walking the streets of a big city. It can be as safe or as dangerous that you choose to do so. The greatest harm done by software AV is precisely its selling point: it makes people feel safe. They can then feel sufficiently safe to take risks, which the software does not protect them. Nothing can reduce the need for safe computing practices.

  I do not leave the safe harbour that once will necessarily lead to disasters, but make a habit of it will weaken your defenses against malicious software attacks. None of the above scenarios must, at the very least, make you uncomfortable.

  6. Java on the Web (not to be confused with JavaScript, to which it is not related, despite the similarity of names) is a weak point in the security of any system. Java is, among other things, a platform to run complex applications in a web page. That was always a bad idea, and Java developers have proved unable to apply it without also creating a portal for malware to enter. Past Java exploits are the closest thing there has ever been a type virus Windows affecting OS X. simply load a page with Java malicious content could be harmful.

  Fortunately, client-side Java on the Web is outdated and largely disappeared. Only a few outdated sites still use it. Try to accelerate the process of extinction by avoiding these sites, if you have a choice. Forget to play games or other uses not Java essentials.

  Java is not included in OS X 10.7 and later versions. Discrete Java installers are distributed by Apple and Oracle (the developer of Java). Do not use one unless you need it. Most of the people don't. If Java is installed, turn it off- not the JavaScript in your browser.

  Whatever the version, experience has shown that Java on the Web is not reliable. If you must use a Java applet for a job on a specific site, Enable Java only for the site in Safari. Never activate Java for a public Web site that carries the third-party advertising. Use only on websites that are well known, protected by login and secure without ads. In Safari 6 or later, you will see a padlock icon in the address bar when you visit a secure site.

  7. another perennial weak point is Adobe Flash Player. Like Java, Flash is declining well deserved, but content Flash is still much more widespread than the contents of Java on the Web. If you choose to install the Flash plugin, you can reduce your exposure to Flash by checking the box marked

  Stop the plug-ins to save energy

  in the Advanced tab of the preferences of Safari window, if not already done. Consider also installing an extension Safari as "ClickToFlash" or "ClickToPlugin." They will prevent the Flash content automatically load and are initially not Flash video is substituted for Flash on YouTube and perhaps a few other sites. I tested the extensions and found them safe, but you should always do your own research before you decide whether to trust any third party software.

  8. remain within the sphere of security, and you will be as safe from malware you can be practically. The rest of this comment is what you must do to protect you.

  Never install any AV or products 'Internet security' for Mac if you have a choice, because they are all worse than useless. If you are required by a (wrong) institutional policy to install some kind of AV, choose one of the free apps in the Mac App Store, nothing else.

  Why you should not use products AV?

  ☞ To recognize malware, software depends on a database of known threats, which is always at least one day to day. This technique is a proven failure, as a major supplier of AV software has admitted. Most of the attacks are "zero-day" - that is, previously unknown. Recognition-based AV does not defend against such attacks, and the enterprise IT industry comes to realize that the traditional AV software is worthless.

  ☞ design is based generally on the nonexistent threat that malware can be injected at any time, anywhere in the file system. Malware is downloaded from the network; He is not of the blue leaves. To meet this threat does not exist, a commercial AV software changes or low level functions of the operating system, which is a waste of resources and a frequent cause of instability, bugs, poor performance, and duplicates.

  ☞ changing the operating system, the software can also create weaknessesthat could be exploited by malicious attackers.

  ☞ especially, a false sense of security is dangerous. This fact relates to all AV software it will never be any changes elsewhere.

  9. a free AV product from the Mac App Store is safe as long as you don't let it delete or move files. Ignore all the warnings that it can give you on "heuristic" or "phishing." These warnings, if they are not simply false positives, see the text of e-mail messages or updates cached web pages, not malware.

  An AV application is not necessary and may not be invoked for protection against malware for OS X. It is useful, or even not at all, only to detect malware Windows and even for this use it is not really effective, because the new Windows malware makes its appearance much faster than OS X malware.

  Windows malware cannot hurt you directly (unless, of course, you use Windows). Just do not pass to someone else. A malicious link in the e-mail is usually easy to recognize by the name alone. A concrete example:

       London Terror Moovie.avi [124 spaces] Checked By Norton Antivirus.exe

  You don't need software to tell you it's a horse Trojan for Windows. Software may be able to tell what trojan is, but who cares? In practice, there is no reason to use a recognition software, unless an organizational strategy requires. Malware Windows is so widespread that you must assume that it is in each attachment until proof to the contrary. Nevertheless, a free AV product on the App Store can serve a purpose if it fulfills a misinformed network administrator that says you must have some sort of application AV. An App Store product will not change the operating system; in fact, it does nothing, unless you run it.

  If you are just curious to know if a file is considered malware by the AV engines, you can download it from the "VirusTotal" site, where it will be tested against most of them without charge. A negative result is evidence of what whether, for the reasons given above. I do not recommend doing this with a file that may contain private information.

  10. There seems to be a common belief that the firewall Application acts as a barrier to infection, or prevents operation of malware. He does not. It blocks incoming connections to some network services you are using, such as file sharing. It is disabled by default, and you should leave it like that if you're behind a router on a private home or office network. Activate only when you are on an untrusted network, for example a public Wi - Fi hotspot, where you do not want to provide services. Disable services that you don't use in the sharing preferences window. All are disabled by default.

  11. as a Mac user, you don't have to live in fear that your computer may be infected whenever you install the software, read emails, or visit a web page. But nor can you assume that you will always be free from exploitation, no matter what you do. Internet browsing, it's like walking the streets of a big city. It can be as safe or as dangerous that you choose to do so. The greatest harm done by software AV is precisely its selling point: it makes people feel safe. They can then feel sufficiently safe to take risks, which the software does not protect them. Nothing can reduce the need for safe computing practices.

• How good is mac scan

  I was wondering what is a commodity good spam. Have opions on scan mac?

  Mac users often ask if they should install "anti-virus" (AV) or software "anti-malware". The answer is 'no', but it can give the false impression that there is no threat of what is loosely called 'virus '. There is a threat.

  1. it is a comment on what you should - and should not-do to protect you from malicious software ("malware") that runs on the Internet and gets onto a computer as an unintended consequence of the user's actions.

  It does not apply to the software, such as keyloggers, which can be installed deliberately by an intruder who has convenient access to the computer, or who has been able to take control of it remotely. This threat is in a different category, and there is no easy way to defend against it. AV software is not intended to and does not, to defend against these attacks.

  The comment is long because the issue is complex. The essential points are in articles 5 and 11.

  OS X implements now three levels of integrated protection specifically against malware, not to mention the protections of runtime such as quarantine the file, execute disable, sandbox, protecting the integrity of system, System Library randomization and randomized address space layout , which can also prevent other kinds of exploits.

  2. all versions of Mac OS X 10.6.7 were able to detect the malware Mac known in downloaded files and block non-secure web plugins. This feature is transparent to the user. Apple calls internally it "XProtect."

  The malware used by XProtect recognition database is automatically updated. However, you should not count on it, because the attackers are still at least a day before the defenders.

  The following restrictions apply to XProtect:

  ☞ circumvented by some third-party network software, such as the BitTorrent clients and Java applets.

  ☞ It applies only to software downloaded on the network. Software installed from a CD or other media is not verified.

  As new versions of Mac OS X are available, it is not clear whether Apple will continue indefinitely maintain the older versions such as 10.6 XProtect database. Versions of obsolete systems security may eventually be affected. Updates to security for the code of obsolete systems will be stop being released at any given time, and which can leave them open to other types of attack in addition to malware.

  3. starting with the OS X 10.7.5, there was a second layer of built-in malware protection, designated "Gatekeeper" by Apple. By default, applications and installation packages downloaded from the network will be run only if they are digitally signed by a developer to a certificate issued by Apple. Certified software in this way has not been checked for safety by Apple, unless it comes to the App Store, but you can be reasonably sure that it has not been changed by someone other than the developer. His identity is known to Apple, so it could be held legally responsible if it distributes malicious software. Which may not mean much if the developer lives in a country with a weak legal system (see below).

  Access controller does not depend on a database of known malware. He has, however, the same limitations as XProtect and in addition the following:

  ☞ It can easily be turned off or overridden by the user.

  ☞ A malware attacker could find a way around it, or could take control of a certificate of signing of code under false pretenses or could simply ignore the consequences of the distribution of malware Tryggvason.

  ☞ Developer App store could find a way around the Apple control, or the control may fail due to human error.

  Apple took too long to revoke some known attackers codesigning certificates, thus diluting the value of the keeper and the program developer ID. These variances do not involve the App Store products, however.

  For the reasons given, App Store, and, to a lesser extent - other applications recognized by signed Gatekeeper, are safer than others, but they cannot be considered to be absolutely sure. "Sand" applications could make to access to private data, such as your contacts, or for access to the network. Think that before granting access. Security sandbox is based on user input. Never click through any application for leave without thinking.

  4. by starting with OS X 10.8.3, a third layer of protection has been added: a "Malware Removal Tool" (MRT). MRT runs automatically in the background. He checks and removes, malware that corresponds to a database of recognition held by Apple. To ensure that MRT will be executed when the database is updated, the App Store tab in system preferences and check the box marked

  Install the system data files and security updates

  If it is not already done.

  As XProtect, MRT is effective against known threats, but not against strangers. It alerts you if it detects malware, but otherwise, it has no user interface.

  5. the built-in Mac OS x security features reduce the risk of malware attack, but they are not and will never be complete protection. Malware is a problem of human behavior, not a behavior machine, and none only of technological solution will solve. Software protect you from trust only will make you more vulnerable.

  The best defense is always going to be your own intelligence. Except perhaps feats of Java, all the known malware, circulating on the Internet wearing reached a completely setting installation to update to OS X 10.6 or later takes the form of so-called "Trojans", which may have no effect if the victim is deceived in their execution. The threat thus amounts to a battle of wits between you and cybercriminals. If you are better informed, they think you are, you win. In effect, it means that you always stay in the shelter of practical computing. How do you know when you leave the safe harbor? Here are a few signs warning of danger.

  Software from a reliable source

  ☞ Software with a brand, such as Adobe Flash Player, does not come directly from the Web site. Don't be fooled an alert of any website for updating Flash, or your browser, or other software. A real alert that Flash is outdated and blocked is shown on this support page. In this case, follow the instructions on the support page. Furthermore, assume that the alert is false and that someone is trying to rip you off to install malicious software. If you see these alerts on more than one Web site, ask for instructions.

  ☞ Software any is distributed via BitTorrent or Usenet, or on a Web site that distributes pirated music and movies.

  ☞ Rogue sites Web such as CNET Download MacUpdate, Soft32, Softonic and SourceForge distribute free applications that have been packaged in a superfluous "install".

  ☞ The software is advertised through spam or intrusive web ads. Any announcement, on any site, which includes a direct link to a download should be ignored.

  Software that is clearly illegal or doing something illegal

  Commercial software ☞ high-end such as Photoshop is "cracked" or "free."

  ☞ An application helps you violates copyright law, for example to circumvent the copy protection on a commercial software, or streamed media recording to be reused without permission. All the 'YouTube downloaders' are in this category, but not all are necessarily malicious.

  Conditional or unsolicited offer from strangers

  ☞ A phone calling or a web page you indicates that you have a "virus" and offers to remove. (Some reputable sites warned visitors who have been infected with the malware "DNSChanger" legitimately. The exception to this rule applies.)

  ☞ A web site offers a free content like music or video, but for use, you must install a "codec", 'plug-in', 'player' 'Downloader', 'extractor', or 'certificate' which comes from the same site, or a stranger.

  ☞ You win a prize in a competition that you are never entered.

  ☞ someone on a forum like this is eager to help you, but only if you download an application of your choice.

  ☞ a 'FREE WI - FI!' network presents itself in a public place like an airport, but is not provided by management.

  ☞ Online everything that you expect to pay is 'free '.

  Unexpected events

  ☞ a file is downloaded automatically when you visit a web page, without any further action on your part. delete any file without opening it.

  ☞ You open what you think, it is a document and you receive an alert that it is "an application downloaded from the Internet." Click Cancel and delete the file. Even if you don't get the alert, you must always remove any download that is not what you expected it to be.

  ☞ An application does something you don't expect, such as permission to access your contacts, your location or the Internet without obvious reason.

  ☞ Software is attached to the email you na not ask, even if it is (or seems to come) by a person of trust.

This technique is a proven failure, as a major supplier of AV software has admitted. Most of the attacks are "zero-day" - that is, previously unknown. Recognition-based AV does not defend against such attacks, and the enterprise IT industry comes to realize that the traditional AV software is worthless.

  ☞ design is based generally on the nonexistent threat that malware can be injected at any time, anywhere in the file system. Malware is downloaded from the network; He is not of the blue leaves. To meet this threat does not exist, a commercial AV software changes or low level functions of the operating system, which is a waste of resources and a frequent cause of instability, bugs, poor performance, and duplicates.

  ☞ changing the operating system, the software can also create weaknessesthat could be exploited by malicious attackers.

  ☞ especially, a false sense of security is dangerous. This fact relates to all AV software it will never be any changes elsewhere.

  9. a free AV product from the Mac App Store is safe as long as you don't let it delete or move files. Ignore all the warnings that it can give you on "heuristic" or "phishing." These warnings, if they are not simply false positives, see the text of e-mail messages or updates cached web pages, not malware.

  An AV application is not necessary and may not be invoked for protection against malware for OS X. It is useful, or even not at all, only to detect malware Windows and even for this use it is not really effective, because the new Windows malware makes its appearance much faster than OS X malware.

  Windows malware cannot hurt you directly (unless, of course, you use Windows). Just do not pass to someone else. A malicious link in the e-mail is usually easy to recognize by the name alone. A concrete example:

       London Terror Moovie.avi [124 spaces] Checked By Norton Antivirus.exe

  You don't need software to tell you it's a horse Trojan for Windows. Software may be able to tell what trojan is, but who cares? In practice, there is no reason to use a recognition software, unless an organizational strategy requires. Malware Windows is so widespread that you must assume that it is in each attachment until proof to the contrary. Nevertheless, a free AV product on the App Store can serve a purpose if it fulfills a misinformed network administrator that says you must have some sort of application AV. An App Store product will not change the operating system; in fact, it does nothing, unless you run it.

  If you are just curious to know if a file is considered malware by the AV engines, you can download it from the "VirusTotal" site, where it will be tested against most of them without charge. A negative result is evidence of what whether, for the reasons given above. I do not recommend doing this with a file that may contain private information.

  10. There seems to be a common belief that the firewall Application acts as a barrier to infection, or prevents operation of malware. He does not. It blocks incoming connections to some network services you are using, such as file sharing. It is disabled by default, and you should leave it like that if you're behind a router on a private home or office network. Activate only when you are on an untrusted network, for example a public Wi - Fi hotspot, where you do not want to provide services. Disable services that you don't use in the sharing preferences window. All are disabled by default.

  11. as a Mac user, you don't have to live in fear that your computer may be infected whenever you install the software, read emails, or visit a web page. But nor can you assume that you will always be free from exploitation, no matter what you do. Internet browsing, it's like walking the streets of a big city. It can be as safe or as dangerous that you choose to do so. The greatest harm done by software AV is precisely its selling point: it makes people feel safe. They can then feel sufficiently safe to take risks, which the software does not protect them. Nothing can reduce the need for safe computing practices.

• Vista: Error 800700c 1 trying to apply the update for Windows (KB2416400)

  As the title suggests.

  The system is trying to update, but it fails.

  This is a security update so I thought it would be important, but can not find a single article about this problem.

  I tried the email support option, and it was unnecessary

  Someone at - it solutions?

  I solved the problem on my own and... surprise!  once more he had nothing to do with a virus.

  You're far, far, far, far from quick access to call virus without having any evidence to support the claim

  Microsoft also has a huge problem of not providing enough logging to help a user to determine the cause of a failed update.  It doesn't help anyone.

  What I have is as follows and hope that helps someone else.  I don't know what point fixed, but the patch has finally been installed

  Connected as an administrator, I did the following:

  -updated to the latest java

  -updated the last flash and shockwave

  -emptied the cache for IE and purge the temporary folders

  -deleted the cache used by windows update

  -removed all is not plug-ins associated adobe (I have some that I need for school)

  -a ran a disk check

  -conducted a scan of CWS to ensure that no problem

  -turned off the startup applications all

  -restarted

  -Ran update as an administrator.

  Miracle or miracles, the installation of the update worked – shocking once, that nothing related to the virus.

  I think that this virus card is played far too often

  Which of these actually didn't solved the problem - no idea.  But it was much better than what is suggested in the recommended response.

  Its this kind of pain that makes people so mad at Microsoft.

• How to wake up the computer from sleep

  I have a Pavilion HPE h8-1100, 64 bit, Win 7 running. When computer goes to sleep, I have problems, he wake up. I tried different keys but nothing happens. Microsoft says to check the manual of the computer, but I don't see anything in the manual that tells me what to do. I end up turning off the computer.

  I found touching the space bar or the 'any' key will sometimes wake him, but if he sleeps soundly, try pressing the power briefly - button not long enough to power it down, just enough to "poke" it.

  I put a power of 'Never' option and called "Virus Scan" for when I want to let it run without me fall asleep on me. -otherwise the darn things NAPs more than my dog!

• W32/Gaobot.worm.Gen.u - Win32/RBot.3eu! Endless screw

  ... okay, I don't remember having that, but...

  under windows, 'reports on problems and solutions', under 'information on other problems', there is 1 called "virus alerts".

  It is said:
  ' Delete the W32/Gaobot.worm.gen.u - Win32/RBot.3eu! Your computer worm

  This problem [I do not know what is the problem they are referring] was caused by W32/Gaobot.worm.gen.u - Win32/RBot.3eu! Worm, a known computer virus.

  This probably happened in the past. so...

  (1) how do for 100% sure that it is my computer?

  (2) so far, I don't think (think, always uncertain) that it is still in my computer. But if it's not then why I have this thing "virus alert" section "information on other issues" under "reports on the problems and solutions?

  EDIT:

  Okay, I think this is related to the b.exe problem, and now I'm not too sure b.exe was never removed...

  Hello

  It says 'delete... '. "To see what those who are Google them.

  Why you think that the methods that you have already been shown several times would not apply?

  No one program cannot be used to detect and remove any malware. Added that often easy to
  detect malware is often accompanied by a much more difficult to detect and remove the payload. If it is better
  to be too full now than paying the price much later. Check with them to an extreme overdose
  point and then run the cleaning only when you are sure that the system is clean.

  It can be made repeatedly in Mode safe - F8 tap that you start, however, you must also run the
