    I'm looking for a good to excellent free AV for Linux. I know that Bitdefender has one for Linux but that's a On Demand scanner and not Real Time. I would prefer a good quality RT scanner.

    Any suggestions would be appreciated.

    ClamAV. It's open source. It's the mainstay on thousands of servers that are using a UNIX-family OS -- see partial list of users HERE.

    I tried this out recently and wasn't impressed. It failed to detect any of my Linux/UNIX samples and detection rates against Windows samples wasn't great either.

    I only played with the on demand scanner (didn't install the RT scanning kernel modules), and I couldn't see any way to delete infected files so, to me at least, it appeared to be a detection only program.

    I'd recommend BitDefender set to run as a cron job as (noted above) it has no real time protection.

    I know you said free, but vexira has a real-time scanner for 150 bucks. Their Linux stuff rocks. Can't say anything about the Win stuff though.

    hi, Albinoni. which distro are you using? if you have Ubuntu i can help you setup something, there's too many to name :cool: but, i use clam mainly, i've setup a front-end (GUI) for it and i can give you a script which you just place in a 'folder' which lets you right-click files and scan them :cool: :cool: it also scans email and automatically updates :thumb:

    you can also do a search for anti-virus (maybe just the word 'virus' by it self would be best for the search) in your Package Manager.

    I'm not sure what you mean by "only at home"? Regardless, I wouldn't say it's an absolute must, but it's nice to have ... Personally I seldom ever use it.

    I'd suggested clam for the OP.

    if it's on your Desktop do this. just cut and paste everything.

    cd Desktop
    tar -xvzf clamav-0.88.tar.gz
    cd clamav-0.88
    ./configure
    make
    sudo make install
    killall gnome-panel

    killall gnome-panel

    you should then find it in Applications>System Tools>Clam Frontend

    Hello,

    While not free, you should be able to request a copy of NOD32 for Linux from your local ESET reseller to evaluate. It is a command-line based on-demand scanner and comes in packages for Red Hat and Debian as well as a tarball for anything using a different package manager.

    Regards,

    Aryeh Goretsky

    I don't think it is necessary to install an AV software on Linux for home users right now.

    Up to now, most viruses aim on Windows.

    One of my friends uses Linux for 2 years. He never install an AV software on it and there

    is no problem happened.

    I have installed F-Prot for Linux on my Linux installations. I scan all of my downloads and do a complete scan from / once or twice a month. This is more to protect my Windows friends by being a good internet citizen than anything else.

    Some QUESTIONS for the experts:
    (1) Are Java viruses and trojans OS independent?
    (2) Are Javascript viruses OS independent?
    (3) Are HTML viruses OS independent?

    Is F-Prot AV for Linux good? I don't know. I have never found anything. This probably has a lot to do with practicing "safe hex".

    Here's a link to a short, but interesting article, "Viruses in Linux":

    www.linux-magazine.com/issue/62/Viruses_in_Linux.pdf

    ""Safe Hex" in Linux - The rules for protecting Linux against viruses in are similar to the rules for other systems:
    1. Never use the root account for regular work.
    2. Avoid running binary files of unknown origin. Check them with rootkit and virus scanners first.
    3. Carefully check every file before running it from the root account.
    4. Keep your operating system up to date. Regularly install official security updates.
    5. Secure your environment by using hard-to-guess passwords and other protections.
    6. Track changes in the system using file system integrity tools.

    Just like Windows!

    ********************
    * Here's some data *
    ********************

    First I captured F-Prot's virus list (as of late June '06) in a text file and then did some searches from the command line:

    > ./f-prot -virlist > ~/Security/fprot_virus_list.txt
    > cd ~/Security
    > wc -l fprot_virus_list.txt (A line count for the file. Not all lines are viruses.)
    176739 fprot_virus_list.txt
    > grep Linux fprot_virus_list.txt | wc -l
    7 (A line count for the file. Lines containing the string 'Linux'.)
    > grep Unix fprot_virus_list.txt | wc -l
    1128 (A line count for the file. Lines containing the string 'Unix'.)
    > grep W32 fprot_virus_list.txt | wc -l
    116978 (A line count for the file. Lines containing the string 'W32'.)
    > grep JS fprot_virus_list.txt | wc -l
    12049 (A line count for the file. Lines containing the string 'JS' or Javascript.)
    > grep HTML fprot_virus_list.txt | wc -l
    1119 (A line count for the file. Lines containing the string 'HTML'.)

    Then I explored the text file in the gedit text editor with Search->Find:

    DOS/Windows: 176179 viruses and 64857 Trojans
    Word/Excel: 8609 viruses and Trojans (a sub-category)
    Script: 19576 viruses and Trojans (a sub-category)
    Java: 10 viruses and 459 Trojans
    Unix: 576 viruses and Trojans
    Unix shell: 539 viruses and Trojans (a sub-category)

    [In addition, approximately 16000 viruses are identified using generic identification.]

    P.S. Results may vary among AV vendors/products.
