I had a similar pop up. It popped up just by itself.
Happened today for the first time , so I checked where it came from as I removed Avast Security long time ago.
I found I still had the Avast Secure Browser installed.
When I executed the browser (left mouse click withour admin rights) , THE SAME POP UP asked if I wanted to have this app (browser app) to make modifications in my computer.
I clicked no, it still popped up.
Could this be a false positive , this is when security software from app X is in conflict with Security App Y ?
