SpyBot has a brilliant little tool called the TeaTimer which monitors writes to the registry and prompts for permission to allow the write to succeed. You would be amazed at how many web ads try to write to the registry. It also builds white and black lists to minimize the number of prompts for permission.

Stopping unwanted writes to the registry will significantly reduce the chance of a virus infecting your computer.

I don't think the above review was with AVG 8.0 based on lower scores against Avast.

Here is a counter review for AVG 8.0. http://www.pcmag.com/article2/0,2817,2291466,00.asp

So another +1 for AVG and Spyware Doctor running in tandem with it.
