Do you have Internet Explorer's popup blocker turned on? Click on Tools then popup blocker. Then get Google's toolbar with the best popup blocker around.

It isn't a so much a matter of spyware, it means stopping the ads that popup.

I recommend you download spywareblaster. It is free.
If you have an older copy of XP perhaps windows messenger is still turned on. It used to come turned on as default. Right click on My comuter , scroll to manage An interface will open click on "services" then 'services" again to the right a list will appear find "messenger" If its enabled, right click on it and scroll to properties. Another interface comes up Click stop under service status Then under startup type open the dropdown menu and scroll to disabled . Click ok. That will stop most popups without a spyware program.
It may be a virus/spyware etc, certainly sounds like some type of Malware unfortunately.
