  An employee had benefited from maternity leave and do not return to work. How to stop its adjustment accounts in the system as she did not join back at work, and is not eligible for annual leave until she is to return to the office.

  -Thank you

  You can change your formula to run only if the State of the assignment is enabled.

  For this employee, change the status of the assignment for leave of absence or suspended, and if the regulation will not take place.

  OR

  An easier way

  Include an entry adjustment that feeds in terms of accrual accounting.

  You can then add or subtract specific employees.

• How to stop DMA FIFO on FPGA?

  Hello

  can someone tell me how to stop Fifos DMA as a target host on the level of FPGA FIFO?

  The node of the method 'stop Fifo' host only erases the fifo buffer on the host side. The Fpga FIFO is still running.

  To reset the whole fpga is not possible, because the running code is important for control of the measure.

• DMA with FIFO data acquisition

  Hi all

  I would like to ask you a favor to get some help to understand FIFO.  I have attached the files here and simply the target more basic FIFO of host data transfer.  I put the required number of elements to 4095, I understand the depth of the FIFO on FPGA.  The sampling rate in FPGA is 10 kHz.  The loop on read host rate is 10 ms.  The depth in the host FIFO.configure is 10000, which I think is the number of items in the part of host of the FIFO DMA memory.  So I guess that the total thickness of the FIFO is 14095 elements.  I put the points of reading in each iteration to 2000 points.  However no matter how to change the combination and number of points to read, the program performs an iteration and then displays a different error message.

  Can someone please help me understand how to calculate each parameter and to optimize it, if the sampling frequency I want on FPGA is data of 10 kHz I16?  Thank you very much.  I appreciate your help!

  Best,

  Charles

  I have attached all the files here, which is very similar to the example on ni.com

  Charles Hey,

  Regarding the second question, it's what I wanted. I'm not 100% sure how the constraint point converts a dbl in unsigned int, so it would be good to use a node of conversion and to probe this value, to ensure that you get the value you expect.

  As for the second question, I told you that you should wiring in a contstant-1 in the field timeout of your fifo method on the RT VI and VI FPGA read.

  

  Thank you

• PCI-6251 vs PCIe-6351

  Hi all

  In another thread here somehwere I spoke getting the smaller possible buffers to reduce latency when reading and writing to the acquisition of card data in a loop.  The "10% rule" came (i.e. setting the buffer size of e/s to 10% of the sampling rate of 100ms per buffer) and although it seems to work on most systems, on some systems, well I can do much better than this, reliable: I can do full Visual Studio 2010 then builds in this loop , using a few sizes of buffers of 20ms, without a single negative overflow error.  It's all about a card PCI-6251.

  I decided to see if I could do better with a PCIe-6351 surfboard, hoping all latency issues could be mitigated by the PCI express bus.  Unfortunately, things are much worse.  On the same system where using 20ms puts in buffer (at 100 kHz sampling) was the test of the bullets; for example I couldn't fail any load I put on the CPU (a quad core Xeon hyperthreading), using the same code with the PCIe-6351 could not even past the start of my loop of I/O without meeting many overflow errors.  I increased the sizes of buffer to 100ms (as recommended by the basic rule), but still have occasional overflow errors, even with virtually no load on the PC.

  Another question, I noticed during the transition to the 6351 that surprised me was synchronization; another application considerably depends on the sync input and output buffers. It worked well on the 6251, taking into account delays caused by the buffering.  The same code fails on the 6351; not with a code error, but tampons are not synchronized.  I did a thorough analysis of this yet (I put emphasis on the first problem above), but it seems that the IO can be synchronized by a partial buffer; in any case, the behavior is quite different, questioning reports cards of the same physical buffer size in each case, using DAQmxGetBufOutputOnbrdBufSize.

  I'm not sure what my question is, except, "huh?"  The biggest difference that I could find on the sheets, is that the 6351 has several DMA channels, which could only help (although I don't think I need more than what's on the 6251).  If someone could shed some light on that, I'm all ears.

  (It was all done using the 9.3.5 drivers supplied with the PCIe-6351;) I don't have the time to go through the pain and suffering that is updated to the NOR-DAQ drivers yet - my company has limited bandwidth and, let's face it, 1.3 GB for a simple driver update is ridiculous, not to mention the time it takes actually install.)

  Hi, JSA,.

  Take a look at your other thread, my first suggestion is to disable the regeneration on your output task.  In c#, use the following text:

  myTask.Stream.WriteRegenerationMode = WriteRegenerationMode.DoNotAllowRegeneration;

  WARNING 200015 can only come when you use regeneration, and it occurs when you copy data on the same portion in the output buffer that the device is being read.  It does not necessarily indicate that an overflow would occur with disabled regeneration.  If you have enabled the regeneration (which is the default) then the unit will try to keep its edge FIFO (8191 samples) filled with data that is currently in the output buffer, so you could get the additional data transferred to the device before you have a chance to replace the previous buffer.

  In addition, you mentioned that "i/o can be out of sync by a partial buffer."  While I don't have too much to go here, I wouldn't be surprised if regeneration disabling fixed this problem as well.  If you transfer a partial buffer of data to the device, and then write the new data, your output waveform may appear out of sync with where you expected it to be.  It is best to simply disable the regeneration, in which case the output buffer is treated as a FIFO, and not a circular buffer, so you're never more than expected.

  Once you disable the regeneration, you will no longer receive WARNING 200015 and I believe that potentially you will not see the synchronization problem.  If the loop of Scripture cannot meet the generation, you will now see 200290 error, which is a mistake of underflow true (i.e. no data is present in the FIFO shipped on time the sample clock is received).  If you encounter some errors-200290 rates and sizes of memory buffer that you think are unreasonable, please do after return and I will be happy to take a look at your code to see if what you see is logical.

  Best regards

• Understanding error '-200846' DIDO in Nibble mode

  Hey everybody,

  the goal is to use a 9401 Records digital lines and output. The digital line is used to trigger a camera, so must be synchronized to the digital input. The point is that I want to record only a finite number of samples at a given sampling frequency. Using the example for the DIDO in nibble mode I played a little with it and I tried to change it to my needs.

  

  However I continue to turn in 200846 error when you try to do. The error is resolved if the autostart of the writing node property is set to true. But it begins the task of writing before the task of reading. I have verified this by plugging the line and line items together. And ideally, this should save 190 values false and true value. But it saves only the actual values, which, in my view, confirms my idea.

  Or is my understanding wrong here? Any help would be greatly appreciated

  Good,

  After a strain of thought freak I came up with the solution, this announcement just in case someone else had the same problem: it must set a schedule. This result is easily obtained by adding the DQmx Schedule VI to the task of output and setting the source as di/SampleClock with the same rate of acquisition and the number of samples.

  I mislead me by my reading and measurement, because I had forgotten to wait until the task of output was made up by stopping and clearing it.

• the 1900 myRIO FPGA multi channel data acquisition

  Hello world

  I would ask you for help in my program acquisition and generation of data. The main task of this program is to measure 4-channel adjustable sampling rate (2 kHz and less) and to generate an analogue signal in up to 50 kHz sampling frequency.

  I created two loops and everyone is dedicated to different operation. The first loop is to measure data, or in writing to the DMA FIFO and the second loop is dedicated to the generation of signals. I adjust the main parametrs of the two loops in a host of vi.

  But what is my problem. I compile the program in the FPGA of myRIO without any problems and I can run too but the problem is that sometimes, especially when I adjust the lower sampling frequency of the loop to measure to the rank of channel changes measured and I see that the signal that is connected to osciloskop AI0 channel on channel AI3. When I stop the program, set the higger sampling frequency and run it again, it works well and the signal is on the right channel. Could someone help me with this problem? I tried to check all the forums that I know, but I did find an article or a discussion of a similar problem.

  Thanks a lot... :-)

  Andrew,

  I just solved the problem. I thought about it again and I got the idea to change the size of the DMA buffer on the side of myRIO. I expanded the buffer of 1023 elements in 2047 and it works well and I can change the sampling without problems.

• Why doesn't Firefox 33 arrested properly?

  I have just had an update to V33 because I did not see this problem before today. I myself was not playing with the configuration in the last two weeks. (Not sure when the last time that I actually closed Firefox successfully, but it was certainly in the last 3 days.) In looking at submitted Crash Reports, I see just one on 10/3 and then 53 of them covering the interval between 19:00 and 20:00 tonight, during which I had to kill it from Task Manager 3 times because it was just hung when it was supposed to be stop. Here's a small sample:

  Firefox seems to operate normally when I restart it.

  I really don't want to have to do a reset to solve this problem. However, if I had to, Sync would push things?

  Back to V32 option? If so, how?

  I'd appreciate any help.

  UH. Never mind. After Windows restarts, it began to close normally again.

  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.

  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.
