Make sure your Virus and adware program's are up to date to start off.
I disabled XP auto-restore and restarted in safe mode, then ran the ad-aware and anti-virus proram's. Follow the instructions when it finds them, if it doesn't then follow the manual removal instructions in the link in the previous post.
As long as you follow the instructions properly you should be able to remove the adware, most removals require removal of registry keys which can be daunting. Do a search on the net for your particular adware and there's bound to be some forums which can help, that's what I did. Them adware and virus writers need shooting, no trial just blammm!. Good luck Bob.
