Tech problem on my puter

[Innkeeper]

Does anyone know how to get rid of SpyWareQuake. It appeared on my puter yesterday while I was on the net, and we immediately encountered all kinds of problems. My PestTrap popped up with several pages of problems which we deleted. Three new programs appeared on my desktop which we deleted on the Control Panel. My homepage was changed which we were able to change back. We found files for it on the Program Files on the C-drive and deleted them. PestTrap still kept finding one or two problems which we deleted as well as the files that were being infected. Right now we are not catching anything, but the damn thing is still on my desktop and won't go away. Any suggestions?
