Well, clamav works with all UNIX like operating systems.  I have it set 
up on my office mail server as a sendmail milter.   In the last few 
months it has stopped 760 messages containing 79 different viruses from 
reaching my 20 users.

Spamassassin also works well on any system really, since it is written 
in perl.  However, since it is written in perl it is a tremendous 
resource hog.

The more proper solution would be to make sure that spam and viruses 
never reach your computer in the first place, so a solution like 
greylisting is ideal see http://projects.puremagic.com/greylisting/ for 
more info.  I don't know how things are set up for you, but these tools 
generally work best at the mail server level, but I imagine that clamav 
could be run to look at files you download.
