What's the best spyware detection software? How about Registry Cleaners?

My wife's laptop computer is very slow. We've tried Spyware Doctor to get rid of spyware and we have McAfee Virus protection and AOL firewall protection. It is just so slow and locks up continually when she's on the internet. Her computer has been used by temps and family so I'm afraid there's a good chance there is an infection.

First off, you're using two programs that are known to use up alot of resources (slow your computer down), Mcafee and AOL. Also, anything related to AOL "is" spyware, get rid of it completely. Uninstall Mcafee, and replace it with "AVG" anti-virus, it's light on resources and it's FREE!! You want a good free firewall, get "SunBelt Kerio", it's TOP-RATED!! To clean out your registry after uninstalling these programs, use "CCLeaner". DO NOT, and I mean, DO NOT ever use "Internet Explorer" as your browser, it's a spyware magnet.....use "FireFox" instead.
