• A PC can operate effectively WITHOUT the need for anti-virus software?

  Come to think if the first PC I've had and the worms Blaster threatened everyone...

  I do not just shoot when to install my anti-virus software, I need to close my Windows Firewall... 2 + 2 = and Yes, when I did I got the virus of shit...

  If only I had not installed the Norton... do you not think that any PC can operate without the need for anti-virus software knowing that you must close

  the Windows firewall and use theres rather...?

  I wonder!

  Hello

  It would be unwise to try to start without antivirus/antispyware are has just too many real threats and
  methods for malware to attack the system. If you attempt to do if of course you have redundant and
  current backups.

  Here's what I use and recommend: (these are all free and very effective versions.)

  Avast and Prevx proved extremely reliable and compatible with all I have
  launched on them. Microsoft Security Essentials and Prevx have also proven to be very
  reliable and compatible. Use MSE or Avast and Prevx, Prevx 3 but not all.

  Avast Home free - stop any shields is not necessary except leave the file system, Web,.
  Operational network (Script and behavior are also recommended in Ver 6 +).

  Prevx - Home - free

  Windows Firewall

  Windows Defender (is not necessary if you use MSE)

  Protected IE - mode

  IE 8 - SmartScreen filter WE (IE 7 phishing filter)

  I also IE always start with asset if filter InPrivate IE 8.
  (It may temporarily turn off with the little icon to the left of the + bottom
  right of IE)

  Two versions of Avast are available 6.x and 4.8 x

  Avast - home - free - 6.x stop shields you do not use (except files, Web, network, &)
  Shields of behavior) - double click on the icon in the Notification area - real time Orange - click on the
  Shield that you want to stop - STOP. To stop the Orange icon to show an error indicator-
  Click on the Orange icon - top right - settings - click on the status bar - uncheck shields you
  disabled - click OK
  http://www.avast.com/free-antivirus-download

  Avast 4.8 x - home - free - stop shields, you don't need except leaving Standard, Web,.
  and the network running. (Double-click the blue icon - look OK. - upper left - Shields details
  Finish those you don't use).
  http://www.avast.com/free-antivirus-download#TAB4

  Or use Microsoft Security Essentials - free
  http://www.Microsoft.com/Security_Essentials/

  Prevx works well alongside MSE or Avast

  Prevx - home - free small, fast, exceptional protection CLOUD, working with other security
  programs. It is a single scanner, VERY EFFICIENT, if it finds something come back here
  or use Google to see how to remove.

  Also get Malwarebytes - free - use as scanner only. If you ever think malware and that
  would be unusual with Avast and occasional Prevx running with the exception of a low level cookie
  (not much), to UPDATE and then run it as a scanner. I have a lot of scanners and they
  never find anything of note that I started to use this configuration.

• Satellite P200D-128 - Question about installed Norton anti-virus

  Hi, I bought a Toshiba Satellite P200D-128 last week and to say I'm majorly annoyed with Toshiba would be an understatement, and that understatement. Fine machine autoinstalled as its operating system, and I found I had Norton anti-virus installed, or at least I thought I had because a beautiful Norton logo quicklink arrived on my desk.

  In fact, only a partial shell of Norton installed and actually have an anti-virus properly functioning to connect on the site of Norton. This arrangement is just stupid, because I am well aware, surf the Internet without effective antivirus / anti-malware is not a question of if the computer will get infected, but when the computer will be infected.
  I have the experience to build my own desktop PC, and basically what I do is install an anti-virus package from the DVD drive with a front disc even connect the machine to the internet and then update the anti-virus software anti-virus Internet home before that I would all navigation on the web.

  Not only have a Norton Quicklink on the center of office crazy to think one has a functioning entirely anti-virus / anti-malware installed, but the partial shell of fools Norton also Windows Vista security in thinking there are a lot of anti-virus installed and it also disables the alert windows system that will remind the user of the computer if there is no antivirus installed package.

  This situation should never have been raised and I think it's a shame. Also criminal elements no doubt major behind the likes of malware, which struck upward on the ploy clever to have infected unsuspecting computer user with malicious software, which uses then the malware to put up a false messages of Windows operating system, which informs the user of the computer has been infected and asking them to download a fake anti-virus packages , must be particularly delighted with this situation, in that a user will be once they see such a message may well click the link of Norton and probably find their Norton is only a partial shell and then install one of the packages most likely fake anti-virus.

  If Toshiba and Norton had deliberately set to infect the computers of users with viruses and other malware, it is difficult to see how they could have done a better job of it, unless they had pre-installed viruses and malware themselves on the computer.
  I wonder, this case went to Toshiba and/or / attention of Norton and if so, what they had to say for themselves?

  Concerning the best and warm
  Adrian Wainer

  PS I forgot to mention that the partial shell package Norton also implements a toolbar in their browser, which reinforces even more the (false) impression that we have a fully functional package of the antivirus installed

  Hey Buddy

  I m bit confused about your ad and how you wrote this.

  I would like to mention a few facts:
  I m a Satellite P200 owner (it s even as P200, but with Intel the piece) and my laptop is equipped with the Norton Internet Security program.
  Of course, it s a subscription for 90 days, but it s a functional full version.

  Everything is pre-installed, but you need to configure and create a Norton account.
  I know because I read the instructions and information that are stored on my laptop.

  If you would in a full version of Norton Internet Security, you must create this account also.
  So you must connect to the internet also if you n t have an Antivirus Program preinstalled to set this up.

  Of course it must be updated also with the Internet because the antivirus definition file changes almost every time and the internet connection is required for this update.
  Why is it necessary? Because the image of Toshiba has designed several weeks ago and, therefore, the antivirus definition files is not updated.

  The same thing happens if you don t use the laptop for several weeks and don t perform the update of the operating system or antivirus.
  Don t wonder, therefore, you must connect to the internet to get everything updated.

  Please don t be angry with me, but I have my own opinion, you are one of the users who don t read the manual of the user or any other information that are equipped with Notepad and could be interesting for the use of the computer laptop but only start Notepad, install a few 3rd party apps and don t configure the operating system that is stored on the laptop.

  So I think that we could avoid this discussion if you read and check all detailed ;)

  Hey Buddy.

• What is the prevalence of viruses, malware, etc., to be hidden and undetectable by anti-virus software?

  • As before, when my computer when my computer has been infected, I get a svchost.exe error, repeatedly, whenever I restart the computer. The infection has been discovered that the last time by my anti-virus software, because it was hidden.  It was a computer expert on this forum who told me my computer was infected by svchost.exe repeated error messages that I received.  I ran my Avast software, anti-malware software from MSFT Security Center, Win Defender, etc. this time, and it has detected no infections.  (Yes, I know what to do to pass this message means not necessarily my computer is infected, but the tech guy said that it is likely, given that the error message appeared on several occasions).  How detect and destroy the virus/malware hidden, etc?
  • Also, if anyone can answer another question... I was told that it is not recommended that I have two programs of anti-virus software, which I do - Win Defender and Avast (I guess they may conflict).  I tend to want to keep Avast, but would like to know if I have to keep Win Defender instead, because it is a Win a Win system program.  If I've got this me getting rid of one of them, is it recommended that I both uninstall and then reinstall one of them?

  A person help would be appreciated!

  Thnx, Dharma

  WHAT I HAVE: Win XP Media Center, MS Office 7 Professional (used at home), IE8, Outlook 7, HP w / 32-bit dual core processor, latest version of Avast & Win Defender, Srvc Pack 2 and 3 (although I know that I don't need 3 because I have not upgraded to Win 7, but it won't let me uninstall it!) and regularly updates Win.

  PS Please ask questions if you have, before you answer, so it will be less likely that I'll get the wrong answers that don't relate directly my questions! (Can say you that has already happened?  (LOL).

  You pouvez have a type of rootkit of malware infection.  Rootkits can transform and change of identity on your OS (and are difficult to detect and remove) and many computing professionals recommend a reinstall of the operating system in order to ensure that the rootkit is removed.

  Follow the suggestions in the Brian - post.  The link that he provided is an excellent reference.   If you have a rootkit, TDSS Killer or one of the other programs listed pourrait be able to remove it.

  You can also:

  For international information see your subsidiary local technical support site.

  Or get assistance from Avast at: http://www.avast.com/support

  You have SP3 on your Win XP OS and if you plan to switch to Win 7 make sure that your processor and RAM will manage Win 7... with your history of technology issues a reformatting/clean install of Win 7 would be a good idea.  Because of the possibility of conflicts, I do not recommend using Windows Defender with Avast or any other resident AV program.  Suggest uninstall you Windows Defender in Control Panel.  MSE and several other AV programs require the removal of Windows Defender in XP (or disabling the Defender in Vista and Win 7).

• anti virus software and the os

  Can someone tell me their opinions on anti-virus software running on a database server? We are windows 2003 / 11g.
  
  I didn't him no permission in the past, but our network of people think we should have installed so we can scan at the C: drive.
  
  In addition, what is your policy of the OS update. I do not update the OS unless I have a problem currently known. Others seem to think this is crazy, but this policy has worked well for the last 3 years. I must add that we replace our databases every 4 or 5 years and they are all behind two firewalls - access is only through the web app or file server.
  
  I would be very interested in other policies.
  
  Thank you

  Personal opinion: I would never put AV on a production to address Oracle server itself,- and 'clean', I mean essentially what you say: it is not directly accessible by the public. It's behind a firewall; It has no functional connection to the Internet, etc. etc. etc.

  We also disable automatic updates on all of our Windows servers, because otherwise, there is a tendency for a production database that you want to die without notice that updates automatic kick in!

  Regarding the manual updates: we tend to not bother on a regular basis. We fully patched a server when we intend to take it offline for other reasons (for example, a fix Oracle CPU), so periodically everything becomes as up-to-date as possible. But during normal operation, we just let it run without interruption (i.e., without updates) for as long as possible. Only

• Firefox 5.0 disabled an add-on, which is associated with my anti-virus software. Is this disabled module if I use another browser too or just in Firefox?

  I just installed Firefox 5.0. I have also just renewed by subscription to Webroot Internet Security Essentials, so I have the updates on that as well, and apparently something in the latest Webroot is not compatible with the latest Firefox. When I open Firefox, I get a message that a Webroot 1.7 'Add-on' and a few files associated with Webroot (I wrote not them down and the error message disappeared) have been disabled. What worries me, because I do not know what part of my antivirus program has been disabled by Firefox. My Webroot reports that it is functional and up to date.

  What he says is that Webroot has a special add-on for firefox which does not match the version of firefox you have. Webroot will still work, but it will not use this special accessory. You may or may not have a similar attachment that it is bundled with other browsers. I'm not sure. All-in-all, the module is not the main part of your anti-virus, it's just a piece of bonus, they give you.

  Firefox has not disabled your anti-virus software, and using another browser will be no more or less dangerous than before that.

  Think of it as a vacuum cleaner. He always goes to the vacuum cleaner and clean, but the small fancy brush to clean baseboards or something does not fit immediately.

  They have most likely only need to change the small part of it that shows what versions of firefox, it will work with, if the chances are that if you keep an eye on, there will probably be an update soon with a version of the add-on that is compatible.

  Saturday:

  • Downloaded a file from a friend who turned out to be infected unknowingly.
  • Contacted McAfee help once a Trojan horse has been "blocked and deleted. At this point when I open internet explorer, you could say that my computer is still infected with something. I would like to enter an address in the browser and would be redirected to another site (i.e. random search, youtube, offer to purchase through my ISP)
  • Ordered to contact Microsoft indicating that it was a problem with internet Explorer.
  • Through a problem with Microsoft where they found a file (cngaudit.dll) that was bigger they said it might be that showed them that my computer has been infected. Tech also found cngaudit .dll (69) where it is said that it was a copy of the original file which showed that my computer has been infected.
  • Set up a time for another Member of the support team to call me on Sunday to help in the kidnapping.

  • After no calls Sunday or Monday, I contacted Microsoft with my # of cases and a second rep attempted to help the elimination.
  • Remote access and technology attempted to run the Scanner again enabled (has been blocked)

  • McAffee is always installed at this time and all the minutes I get a pop-up indicating that 2 (located in the temporary file) Trojan horses has been blocked.
  • Called Microsoft a 3rd time and met with an another tech once again connected via remote access and "worked its magic" like others and recommended I have remove McAfee and reinstall because the alerts I receive are "fake".
  • Remove and reinstall to see that McAfee will not be updated or protect. Now the tech suggested that I contact my ISP for assistance because McAfee has been downloaded from their site and seems to be defective.
  • Contacted my ISP and was told to contact McAfee.
  • Contacted McAfee and told to contact Microsoft.

  Wednesday (2 a. .m):

  • Always at work, trying to get something to work. Attempted to run the cleaning (ERROR: the instruction at 0x00cb34ef referenced memory at 0 x 00000000) The memory could not be read. Click on OK to terminate the program.) Attempted to run the disk check (went through the process and when the system has restarted, he received an ERROR saying that my computer would have to close and restart)

  • Attempted to launch the Scanner and even once, was not allowed.
  • Downoladed Malwarebytes'... put up-to-date, but as soon as the scan began to close.
  • Downloaded SpyBot and scan it again just to make it stop after the update.
  • A run ESET Online Scanner and found 2 objects (files win32)... cleaned and removed.

  Where am I today? I can't always run antivirus software and my computer is currently not protected... online security with networking Mode.

  Any suggestions?

  You cannot save your programs - a clean installation wipe everything from the hard drive.  Programs need to be reinstalled (they cannot be copied or saved) - and you probably wouldn't do anyway because there is a good chance that some of the infected files can reside in these same programs.  The ONLY way to avoid this is to get your hands on a real Windows Vista Installation disc, so we can attempt a repair system/upgrade where your programs will be preserved (and we don't know yet if that will completely solve the problem of infection but it probably will restore the functionality at least for a certain period of time).

  Sorry for the bad news, but that's just how it is.

  Good luck! Lorien - a - MCSE/MCSA/network + / A +.
