As you might imagine, I have a PC with rather a lot of viruses on it, 
for testing stuff, and all sorts of virus-laden email. A lot of the 
time, I don't use any anti-virus software at all, as it just gets in the 
way. But when I do, I use different software (F-Prot) than the one we 
have a site licence for (Sophos).

I think running different AV on the gateway from what you run on the 
desktop (if you are limited by financial constraints, and cannot run 3 
on the gateway) is a very good idea. If Sophos is a bit late in getting 
the detector update for the latest new worm, then you don't want all 
your layers of protection failing together. If you run the same software 
everywhere, it will all fail at the same time, demolishing your 
defences. You want multiple, different, layers of defence.
