My name is Jeff with SecureLive, one of my personal favorites is Kaspersky (http://usa.kaspersky.com/
). Kaspersky does one major thing that others do not do nearly as well. I am a programmer plus SecureLive cleans up sites almost daily. Kaspersky has the ability to search your source code to look for root kits, base64(decode even if it is gzip inflated. It will find most of the hacks found in websites pretty quickly. This is not a 100% clean up job though as like ALL security software the back door still exists somewhere, so if you are needed to just clean up a site, then NO off the shelf security suite will do the job. If you need to clean up your computer, all most all of them are pretty equal. It is mostly the difference between a Ford and a Chevy.
