What are the independent, credible web sites that rate anti-virus and malware software?

Hi Experts,

I want to find the best anti-virus and malware protection software. I search the web for sites that rate anti-virus and malware software.  Once found, I don't always know who is behind them. Sometimes I wonder if  some of the sites have an alternative motive, such as selling more of their software.

What are 2 or 3 excellent, independent, credible web sites that rate anti-virus and malware software?

Thanks!!!
