How to clean up computer?

Question

My computer has been doing some weird things lately. I have run a scan with McAfee and it does not detect anything except onestep Adware, which cannot be removed and has nested itself in my D recovery partition.. Some of the weird things are internet browsers crashing, and overall slow performance. My 224 GB hard drive is about half full though. I ran sfc /scannow and after the scan it prompted me to insert the XP disk, which I do not have because Best Buy did not give it to me. What it the best malware detection program, if there is one? Then what do I do about removing it? If I install vista, will it delete the adware that I have and any other possibly malicious programs? Thanks for the help.

Answer 1

you could try windows defender, comes installed on vista but i'm sure you can d/l it from the microsoft site for XP then run a scan, if that dont work go to big fix.com, it's free software that detects problems with you pc and auto corrects them.. malware and spyware included. hope it helps
