sig, thank you for responding. I do not know what was installed - I did nothing to agree to it that I am aware of. One day I was surfing and my screen went crazy. Next thing I knew everything was google, too many ads. their tool bar I think was also installed. Went to their website and can't find info on how to stop them.
They also took over my iPad and I thought that was taken care of by holding down the home key and turning off iPad. Ads are less but still being redirected.
Firefox is my primary search engine. However, I do have Gmail and they own that . Is that part of the problem?
I appreciate your help.
