One PC on our network just got hit by the Swen.32 worm and could not be fixed. I downloaded the Symantec removal tool to the server and a floppy (from another PC), but I could not access it because the worm completely disabled any disk access. I went through various attempts to reinstall WinXP by booting from the CD. First I tried Repair, and that didn't work. After several failures in the middle of reinstalling WinXP I was successful, with XP ending up in a new Windows folder. The original Windows folder, WINNT (NT was the original OS before the upgrade to XP) was still there and, I now have a dual boot option when I reboot. Fortunately, the default is the new, working XP. My question is (finally!) how do I safely blow away the WINNT folder and the dual boot option?
