I think I have spyware on my computer please help! I have tried everything.?

I have Windows 7. Microsoft XP. 1 Mth old computer. I downloaded what I thought was Active X. I started having problems with popups and I didnt think nothing of it. I turned popup blocker back off. It started getting worse. Also, when I open more than one internet explorer browser then IE will close and tell me it was an error and it will reopen my pages for me. I ran my spyware tool (Ccleaner) and my antivirus program and found nothing. I went to the Control Panel for anything suspicious and found a RaveGame Toolbar that I deleted. I downloaded a free trial of Spyware Dr and deleted the registry keys that it found. And restarted the computer. I thought everything was ok until I tried to get on two websites together again. I think the popup problem is gone but not for sure. Please help. I also done a backup of my computer before deleting the registry. If i use the backup, if needed, will the spyware be back on my computer. Any help is appreciated. If you need any extra information email me at ajackson3036@yahoo.com.
