I am just tired of all the problems with Avast lately.
I did clean installation several days ago because of different problem and that was fixed.
I was able to import settings without any problem.
Let me guess,solution is repair,clean installation…
Maybe solution is to dump Avast.
I am actually doing something on my PC and I just don’t have time or nerves to fix problems with Avast.
Looking at Beta section it looks like next version is only going to be worse.
To be honest I don’t even need “whole” Avast,only Web Shield.
