Ok, so you are disappointed with avast and probably need somewhere to vent...fair enough.
There have been assumptions from both sides in this thread (that it was your fault, or that avast don't care etc...) which are pretty much wrong as far as I am concerned.
Beta testing, by it's nature will NEVER catch every problem, as you are always testing a small subset of the userbase (and by extension the different configurations)
Look at it this way. Assume that only the people on this forum were beta testers (wrong, I know. Only some were testing, and there are others who may not be part of the forum but test also)
There are 240,129 registered members right now. Lets assume that they are the ones that beta tested.
So out of the 150,107,324 active users (from website) this represents a ~0.16% of the total userbase that is testing the beta versions. Less than 1%.
Now, there are some assumptions there, but I think it is fair to say that the actual value is probably lower than that. This means that there are at least 149867152 (99.84%) potentially unique setups that are untested.
Every release will introduce more potential bugs that may not have been present in previous versions, and this will not be seen until it is released.
avast wouldn't have released a version that they felt that was ready, and they do care. They wouldn't still be in business if they didn't.
Was the beta period rushed? Maybe. I guess the only ones that really know will be avast. We are after all, just users.
You had problems with avast, which will hurt your confidence in it. That is understandable, and your decision to choose another one is also understandable. Some of the responses in this thread were unnecessary and probably made things worse for you, which never helps.
I guess the only thing that can be said, is it is unfortunate that you had issues, and that I hope you have a better experience with whatever you choose from now on.
(I never understand why people make such negative comments when a user posts a topic like this...I am pretty sure if I experienced the same, I may be inclined to act the same.)
