The downside to Sophos is that it costs an arm and a leg, especially
for mail server use. F-Prot used to charge on a per-server basis,
although I've heard some mention that they may have changed their
pricing for mail servers.
Is f-prot really that slow? Back when we were running the
command-line scanner version, it seemed blisteringly fast. I often
had difficulty even finding it in the process table with mails coming
in at a rate of 1 or 2 per second. We've since switched to the
daemonized scanner, which is quite fast, especially with amavisd-new
which knows how to interact with the scanner directly, saving at least
one fork(). Even still, SpamAssassin processing is a least an order
of magnitude slower than any virus scanning, so it isn't a huge deal
