I tried to see the google toolbar, but says that I cannot do this. See an adminstrator… I own this computer so. not sure on that.
I opened up Avast internet browser cleanup, and reset to default values. I now have bing with a lot of cows on the screen. That is fine, but no google chrome toolbar.
Regardless the rectangle is not there again today, so I think so far so good, probably solved. Thank you.
