Depends on your resources. From best to worse:
1.Make a BartPE live Windows boot CD. Requires a working computer with XP or 2003. Load AdAware and Avast! on there. Boot up with that CD and use it to clear it of its ills. Works fine on W2k machines.
2.Download HijackThis! and run it on that computer, checking the results on a working computer.
3.If you have WinXP updates, do a run>msrt to run the Microsoft Malicious Spyware Removal Tool. Or download it from
http://www.microsoft.com/downloads/details.aspx?FamilyId=AD724AE0-E72D-4F54-9AB3-75B8EB148356&displaylang=en. Then do Add/Remove programs first in safe mode, to get rid of the bad and obvious stuff, and remove other stuff slowly in AdAware.
4.Restore point.
5.Reformat.
