Looks like my Windows XP Pro box at work got infected with win32blaster last night. I thought the Windows admins pushed out all the patches on a regular basis, so I'm surprised by this one - it's actually the first time since I've worked here that my box has picked up a virus. Anyway, at least one of our main internal web sites is down, probably being DOS'ed by our own machines. Lovely.
Good thing I always install and run ZoneAlarm on my home machines. I'm pretty sure they're patched but I'll make doubly sure tonight. It's also a good thing I have a Sun box sitting on my desk as well. :)
Update: all patched up.
