You need to distinguish between Worms and Viruses.  Worms are just
propagating themselves.  There's never any harm in dropping a worm
since they are not part of a project or a correspondance.

Viruses on the other hand attach to otherwise legitimate files and
of course they should be bounced.

I know if I was hosted and my hoster was propagating worms that
forged my name I would be looking for a new host.

Clamav distinguishes between Worms and Viruses in the name, but
not in the return code as far as I know.  For most milters it
wouldn't be a problem to grep the output for the "Worm" in the
name and drop them in /dev/null.

Another way to handle it is to have clamav on all your MX hosts
and report 4xx fatal errors to those that try to send you a worm/virus.
For worms you know you are talking directly to the SMTP engine of
the worm (since all MX hosts are running the software) and so the
error code cannot cause a bounce.
