[unisog] Your opinion on your AntiVirus product?

We run Sophos and ClamAV on the SMTP gateway, along with a number of
heuristics (no double extentions, multipart archives, .cmd .com, etc.).
A message must pass all three before being accepted.  These are all done
with MIMEDefang, a sendmail milter.

On the desktop we supply Norton Antivirus.

ClamAV and Sophos are close in the viruses they block, but there are
some differences with ClamAV, usually, catching a few more than Sophos.
But, there are times Sophos is quicker with a new virus.  ClamAV also
blocks many phishing attempts.

Norton is usually the slowest to provide patterns, but then it has a
much harder task (virus clenaup) than Sophos or ClamAV, which just need
to detect.  On the Exchange server we also run Norton.  The Exchange
server is behind the SMTP machines, which catch most viruses from
outside the WIN domain.

We also block outgoing port 25 connections from most on-campus hosts.

Despite all this, viruses do slip by.  And, there are many other virus
vectors not covered.
