Many companies make anti-virus software that runs on a Linux server, but
they're all designed to find Windows viruses with the assumption your
box is a mail or file server.
Linux doesn't really have a virus problem, and even if it did, as long
as you're not doing day-to-day work as "root" your box would still be
pretty safe - only the file accessible as the user you're operating as
would be vulnerable.
Worms are a different story, but as long as you're not running
unecessary services and keeping up with security updates, you should be
safe there also.
I've seen a few mail virus scanning tools, and a couple of open-source
virus scanners as well, by scanning through Freshmeat.
