I didn't realise when I was clicking accept again and again until too late.
Also my home page is now bing...how to get rid of that?
Unfortunately you are now dealing with MicroSoft who will do all that they can to promote their own money-making schemes.
I've long railed against the advertising policy; if you're very, very quick you can hit the "Hide Ad" button and then it will continue to display the "Show Ad" button.
If you're not quick enough, the ad appears and the "Hide Ad" button disappears - forever in that session.
As for "bing" it's Microsoft's answer to Google and a poor one at that. Change your "Settings" in Google Chrome and leave IE alone.
