I've never heard of XP Anti-Virus. Where did you get it? (Edit: Do you mean Windows Defender?)
Try downloading Lavasoft or McAfee Free from a different computer (onto a flash stick) and put them on the XP. Lavasoft should be able to get rid of the problem one for you.
If you have some pretty bad nasties, you might have to fix them in safe mode. Hit the F8 button when you turn your PC on.
