NOD32 is the only software to date that can erase the worm that causes the infected user to send something like "Check our pics on myspace: ____________________". It links to an .exe file, which when clicked will cause your PC to send those annoying messages too.

I've already seen 2 of my buddies have this symptom, and no thanks to WLM's unfinished status manager, I can't sucessfully block them. But since they'll be on MSN when they're spreading the worm, they'll take notice of an e-mail. Use that opportunity to link to anyone's whos infected about NOD32 and tell them to stay the **** off MSN until this gets solved, or use Meebo.

(BTW this ain't spam, I use Mcafee for the least annoyance when it detects a virus or a PUP.)
