It could be something completely different but I'm getting desperate: I might have a problem with my iMini combination Norton Security 7.4.0. Recently I noticed that every time I did a search online I would get a Norton result page starting with a lot of adverts above the real results (instead of the normal google look & feel). At the same time I noticed that my mouse started freezing. This could be fixed with replugging it into the keyboard. Just now I got online again.. to my surprise the mouse freeze is at nearly 0% AND I don't get the Norton results anymore after a search request. Any connection between the two?
My iMini runs on MacSierra 10.12.6
