A spam filter like Spambayes (see my .sig) will do an excellent job of
weeding these things out given a small amount of training. Since each
anti-virus tool seems to generate this stuff in a unique format, using
purely pattern-based detection is going to be less effective than using a
statistical approach. As a MacOSX/Linux user who's generally unaffected by
the virii themselves, the quarantine/defang/delete messages many anti-virus
tools send out present the greater problem for me.
Using a purpose-built spam filter simplifies your procmailrc files to boot.
I realize there is an "Everest Effect" for some folks that makes it
attractive to implement such tools directly in procmail, but I think most
people will find in the long run that supplementing procmail with a
purpose-built spam filter is both easier and more efficient.
