Also enabling a firewall, like even one such as the Internet Connection Firewall built into Windows, will help to prevent getting it in the first place.
This worm hit my campus between yesterday and today, and proceeded to infect every computer-based testing workstation we have... and it's finals week. I've really never seen something spread so quickly. We imaged a lab this morning and they were all infected easily within an hour, if not less time.
Needless to say, I got a nice 8-5 day as a part-time working student... heh, so this is what real life is like?
