In case anyone gets this problem and doesn't know the ropes with XP....

Norton told me Trojan.KillAV was in C:\WINDOWS\ppypon.bnd and could not be deleted by Norton. I rebooted and hit F8. Nothing happened. Could not get into dos. I was ticked off. Tried a few more times, different ways.

Then, I went looking. All programs, accessories... there it was... C:\ Command Prompt. I deleted the file. It was not gone. Same thing next attempt.

Then, I deleted it twice in a row, and when I tried to delete it again... file not found... success!
