Recently my computer started having spyware pop ups on my desktop. They told me that my computer was infected with spyware and that i needed to follow the link to this website in order to get rid of the problem. They were advertising two products called PC AntiSpyware and PC Cleaner. It stated that both these programs would run on XP (which I have). Since then I have been notified that both programs were illegal. I scanned my computer with Norton and no spyware was found. However these popups keep occurring. They are rather annoying and slow my PC down quite significantly. I really would appreciate it if someone could please tell me how to get rid of these popups.
