McAfee total protection is the best I think.
Try the free virus scanners at http://blog.360.yahoo.com/blog-sAFtLsc8e... and see which one will help you .
I am not impressed with Windows Defender at all! Try some of these. This is a list I have compiled of what I feel are the best free-anti-spyware/anti-malware websites. When I use them together on my system it does an excellent job in keeping it clean.
