whiz,
Do let Stinger try to remove the pests. If that does not help resolve the situation, it is time to use Liam's "Hijack This!" so we can see where the problem is located in your system.
If we do not find it there, it is time to do a fresh install of WinXP on top of itself to sever the ties of the Malware with WinXP. (Then we can run all the programs, i.e. HouseCall, Ad-Aware, Spybot, Stinger, etc. and remove every pest in your system.)
Take Care,
Richard
