I frankly don't care about false positives they mention, because the way how they apparently test them is utterly stupid. In real-world test avast only had 1 false positive in the entire year 2014 and in file detection it had 100+ in just last 2 tests. How can it be best and worst at the exact same thing. It makes zero sense. That's like saying Volvo is the safest and least safe car at the same time. Make up your mind is what i'd say to AV-C... And it doesn't matter what testing methodology they used, results can't be contradictive for the very same thing.
