Customer feedback (positive + 'negative' = positive)
As to ‘negative’ feedback, there are really two types, the 2nd one of which actually turns out to be positive – 1) something akin to scribbles on a bathroom wall and tells us no more than a general “you suck” (one suspects these could be a competitor taking a rather unproductive approach to PR); or 2) constructive feedback that helps us make our product better (this we like, as it helps us all – developers, QA, Virus Lab, marketing, and especially… the entire community of avast! users).
