Virus Protection - Unix Specific Instructions.

For unix we recommend CLAMAV as the primary scanner, it's easy to install on most unix systems and gives a good broad protection.

CLAMAV Settings.

These will be set in surgemail.ini by the auto config button: (path to clamdscan may vary)
    g_virus_cmd "/usr/local/bin/clamdscan --stdout --no-summary --remove $FILE$"
    g_virus_cmd_codes "1"
    g_virus_strangers "true"

CLAMAV Installation

On most modern systems you can install clamav by typing:
sudo apt-get -install clamav

That should be all you need to do, then use the auto configure inside surgemail's virus page to set surgemails settings and test it.

If that doesn't work check this page for Operating System Specific packages for most versions of linux, or if all else fails you can follow the build from source instructions:
