In my opinion, Avast Wins in what (to me) is the most important test category, "In the Wild 360 / Full Spectrum Test Results."
The 'win' is valid if you give more points to 'behavior blocks' vice signature blocks -- which I do.
I used to consider Avast as kind of lame. But they seem to be doing well lately.
