AVG have released a version of its free AV product for Linux.

See: http://free.grisoft.com/doc/21/lng/us/tpl/v5

I had a look through the user manual, seems fairly easy to use for the basic functionality (even has the GUI) but if you want to set up on-access scanning it gets a lot more difficult.

Infact the manual is not that clear on this stuff because it mentions setting up on access scanning for Linux email server machines which confused me a bit because that is a different AVG version altogether.

I have attached the user manual for those interested, I think I might have a bit of a play with it but might leave out implementing the on-access scanning for now as I am not confident enough in my Linux skills.
