    I want to add that most Linux users do not run Clamav or any other AV software (apart from the fact that Linux is allready a good AV tool in itself). Only eception is when they have to deal with files coming and going from/to Windows systems and thus want to suppress Windows viruses as a service to the poor Windows users.

    So before you install Anti Vurus, please be sure you need it.

    Hi Henk
    I was of the same opinion up to recently when I tested google chromium....just for one day then I got rid of it. Chromium imported a trojan !!! which I found via clamav (which I installed for test purposes).
    Then I looked at the clamav virus database. ... the number of linux viruses made me write this howto.
    Thanks for the comment.
    cheers Otto

    Nice that people say they exist. But I haven't seen one case here on the forums. And look around on the Internet and try to gather a list of Linux viruses that did harm to the system (and please report here, I and many others here would be interested.

    But of course, everybody is free to install one or more of those packages.

    FWIW, I run Avast A-V as a weekly cron that scanning user data folders.
    Much easier to configure than ClamAV, comes with a GUI interface, virus database updates daily if desired.

    Its called Avast for Linux or Avast for Workstations.

    I like daily updates !!!
    Does Avast integrate into Kmail and Firefox ? By the way Clamav has GUI interface too.

    No I don't think so for Kmail or Firefox but I've never tried it.
    Check the Avast web site to see it they've integrated direct email support.
    Firefox has been so slow lately that I'm not sticking anything in there to slow it down.

    I just run the weekly cron to update the virus defs and scan the folders.
    Sometimes I run an individual file scans if I want to move a Windows file just downloaded.

    As others wrote its mostly for the Windows files I download in Linux that I run the scan.
    The danger isn't from Linux viruses, the danger is from infected Windows files and OS independent files like .pdf, .jpg, mpg, etc.
    While a virus could be hidden in a .pdf or .jpg file it wouldn't run on Linux but that same file might infect your Windows box.

    Now that you mention it, I don't. I have boxes for Mass Effect2 and other games but not Windows.

    no! chromium didn't import a trojan, instead ClamAV looked at chromium
    and incorrectly decided that chromium itself was a trojan!

    see the answer to your original sky-is-falling posting by techwiz03 here:

    please provide here a link to the list of _Linux_ viruses which ClamAV
    looks for..

    i'd be VERY interested in seeing that list...because i've been using
    Linux since 1998 or so and so far i've never seen the name of ONE,
    much less a _list_ of viruses which attack Linux systems

    please stop acting like a proprietary-pusher trying to FUD up the
    Linuxscape..

    there are no known Linux viruses....sure there are root kits readily
    available--but as far as i know ClamAV has no idea how to look for
    those!! for the non-windows user ClamAV is nothing more than a cpu
    cycle waster.
