Since the latest version of Avast, the one with the gray left side, users are getting advertising spammy alerts.
They can be annoying.
How to disable them or at least make them less visible?
Open Avast, go to settings, select “appearance”.
At “Popups”, select 1 second for info and update popups.
Leave the rest of them as they are by default.
Scroll down for “community features”.
Uncheck both options from there.
You won’t see those popup/alerts anymore.
