Dear Avast,
Having been researching this problem, I have seen that there are an alarming number of users that are extremely dissatisfied with your product as a result of the “http://aos.avast.com/upgrade/2006 pop-up-tab” issue. I suggest that you correct this problem as quickly as possible. Otherwise, you will find a large number of your customers have switched to a competitor like AVG. Non-interference is the primary reason that many of us choose and recommend Avast. If we wanted our security system to get in our face all the time, we would be using McAfee!
Thank you
