    What do the anti-virus definitions mean?


    Hey Guys!

    I've been thinking about this for quite a long time. Whenever I used an Anti-Virus Software such as, McAfee, AVG Internet Security, etc. When it found a malicious program is used Malicious-File Definitions such as: Win32/Sality, Win32/Virut, Worm/AutoRun, Win32/Zbot.G, VBS/Heur. But I don't know what any of these mean. Can you guys tell me more about malicious files?

    The name is one given to what the AV people consider an 'infection', and seems to be based on the enviroment (Win32 being somethign that needs Windows 32 bit (but will work in 64 bit too), and VBS probably being a form of Visual Basic), followed by a name based on either something inside the file or based on the overall mechanism used to infect - hence getting numbered occurences of things.
    What they actually are is best looked at on the AV software site to see what they have to say about them.

    Antivirus programs must keep an updated database of virus types. Database includes a list of "virus definitions" that the antivirus software references when scanning files. Since new viruses are frequently distributed, it is important to keep software's virus database up-to-date.

    This is very much important to fight against latest adwares and malwares that easily get your computer.
