I was wondering if it was possible or even acceptable in adding a secondary Anti-Virus program. I know in the Scrollout F1 installation info he has an option to ad on another program such as Bittorrent or Kaspersky or AVG. Not sure if you can but I thought I would ask. Also if yes than HOW? Thanks.
Amavis supports several additional antivirus programs, it should be enough to install them and amavis should pick them up automatically. You can see the supported antivirus programs listed in the amavisd configuration files.
