I have to politely disagree…there really aren’t that many bugs with this version.
What you see posted are the extremely minute number of users with issues.
The vast majority who don’t have issues rarely post.
Please keep in mind avast has over 200,000,000 users worldwide.
If you choose not to do as Eddy advised are you willing to attempt a repair?
Control Panel>Uninstall a Program>double click "avast"click “repair”>reboot
If you are unwilling to accept our advice/suggestions there is very little we can do to assist you.
