Actually SpamAssassin can be quite effective at trapping viruses. I find 
that it traps pretty much every virus that comes my way (and that's 
quite a lot -- several hundred a month).

It doesn't do this out of the box, but as most popular viruses come as 
some form of MS executable (exe, bat, pif, scr and so on), all you have 
to do is to increase the spam rating of MS executables. I have the 
following lines in my SpamAssassin prefs


Between them, and taking into account any other spam indicators, this is 
enough to intercept viruses (which requires a score of 5.0 or more). 
Unless you are frequently sent legitimate MS executable files, of course.
