I recently started using clamav, mainly because it's free. Can't say anything
about effectivity and performance yet.
But I also don't expect to catch many viruses in email since we're running
mime_header_checks:
===============

================
(activated by
mime_header_checks = regexp:/etc/postfix/mime_header_checks
in main.cf, of course)
anyway, so all of the recent trojans have been caught before they came to
the virus scanner. Word/Excel macro viruses seem to have declined, but for
these you'll still need a virus scanner.
