Oh my God. This has been going on for more than a year. That's really frightening.
I'm a Windows 10 user, so in my case, this problem can't possibly be blamed on a legacy OS.
I'm getting these extremely intrusive popups that are wreaking havoc with my efforts to do video capture with Camtasia. When I am making a video and these little popups occur, it forces me to pause, edit the video and generally lose lots of time. This is outrageous. I DID INSTALL the goddam update it prompted me to install. Multiple times! DOESN'T help. It keeps prompting me to install it again, and again, and again. Following instructions here and in other forums where lots of people are complaining about this same problem, I do the following:
Settings -> Protection -> Updates Off / Notify Me Off, as well as
Settings -> Application -> Application Updates Off / Notify Me Off
Does ZERO good. The settings instantly relapse to their defaults, completing ignoring my attempts to configure updates and notifications. The configuration buttons in Settings are there for show only. They do NOTHING.
I love Malwarebytes, but this is extremely annoying, and I really don't appreciate the prissy moralizing sarcasm of jackasses like digmorcrusher, so please call off your brown-nosing pitbulls and toadies. Try to be good customer advocates instead. Delete her offensive comment above, make this a safe place for customers to make complaints without being insulted, i.e. please limit this forum to people's complaints and the solutions you offer.
