Just to be pedantic, that's more of a worm thing than a virus thing. My
stats were only examining email-born viruses, which have tailed off a lot.
Worms (like blaster) do scour the internet for unpatched boxes with public
IPs, and I expect you're right that with the roll-out of XP SP2 (with
default "on" firewall) and other things, the number of worms has gone down
too.

So we get all the virus writers jumping on other ways to get into systems.
This is where the onion layer approach to security really comes into its
own. You can never guarantee an internet-connected box isn't going to get
taken over - the trick is to minimise the impact. Even if it's a standalone
box, not on a network, you can still take regular backups and store them
either on WORM media, or on a hard disk you don't leaved plugged in all the
time.

Yeah, there's a good load kicking about on IM as well - mostly which will
take over your IM programme and start sending itself out to all your
contacts.
