Yeah, this is f***ed-up. I just upgraded from Win98 to XP (finally). I am positive that I did NOT have this virus two days ago, because the last thing I did was check my running processes with msconfig. Then after installation completed, I went to Windows Update and installed 28(!) updates. I also downloaded drivers for my sound card (from Gateway and Creative's websites) and for my scanner (from Driverguide.com). Then things started getting sluggish, and my comp kept rebooting without warning. I ran msconfig again and sure enough, there was msblast.exe! Luckily I caught it and removed it before it did any damage. Now I just wish I knew exactly where I got it from. :(
