Hi
You really need to make your computer more secure from malware. I would advise you update your Windows and IE Browser security to minimum of SP1 to start and SP2 when clean.Is there any reason why you dont have it ?.You are wide open to infection with raw XP.Once you hit the net again you could get reinfected and that would all be a waste of time after carrying out the cleaning..
