I have got a NEC.EXE program running into my Win XP as soon as it finishis to boot. It truns my antivirus off and don't let me to open the Task Manager to kill it's process. My Proxi (Zone Alarm) has avoided it to contact external remote servers. So I think that I am still safe if I can remove the executable file. I would like to avoid reinstal de OS and all my stuff back. I format a disket with a DOS boot but I can only see A:/ drive after it.
