your survey needs an answer to cover the situations where avast simply cripples machine performance such as in the case with winXP, where avast literally causes the machine to take 10 minutes to boot and interferes with USB IO (avast causes all sorts of problems with my scanner).
but really guys, harden the heck up and add an option for “I’M NOT HAPPY WITH THE PRODUCT AND OR PERFORMANCE”
I mean if you really care why people are uninstalling don’t create a survey that glosses over customer dissatisfaction
