I would not have installed this version, but the damn software did the damn update automatically.
THIS VERSION SUCKS!
Every new version of Avast is bugged, it's always beta and never tested.
So it's not a big surprise that the AVAST UI is now eating half of the CPU, almost 50%, ALL THE TIME. It's impossible to play a game or do something usefull, as my computer is slowed down by this bugged software.
Why? Are Avast trying to trick me into buying a new computer or something.
I have reported the bug/error, but I don't expect that this bug would be corrected any time soon.
