I recently made the mistake of installing Avast, and it does the same annoying garbage. The actual settings are buried under a metric shit ton of "Did you know that...?" pop-ups that appear every single time no matter how often you select "do not show me this again", and it constantly urges you to buy the "premium" version for extra features that are literally useless to me.

And it was a pain to uninstall as well. Some files survived the official Avast uninstall AND separate uninstall from the Task Manager, and messed with the Windows Defender, which was unable to recieve updates for a while until I found and nuked the hidden residue of Avast.
