Reading this entire post I need to ask, What version of Avast (paid) is considered a stable version?
hi ProTruckDriver,
As your question is not really about the updates themselves, but tending to go in a different area regarding system stability, it would be perfectly ok to start your own topic just specifically about that issue.
Having said that, bugs in a version of Avast!, paid or otherwise, often do not show up until the final version is released to the general public.
User systems vary widely on how/what they are configured, what operating systems are installed, on what programs was/were previously installed/removed, and/or the use of "registry cleaners", so the range of configurations is almost infinite.
Avast! has been very good in fixing any issues that come up, and here we provide any support you may need for free, so...
