First try successful
I don’t give up easily on a problem - I believe that a little research and a lot of determination can fix most Mac problems. But I had to give up and buy an Adware Doctor to solve my problem. So reluctantly I spent the money on this app. Fortunately, my first use of it seems to be entirely successful. It has also optimized my browser, either intentionally or unintentionally. So I recommend this app to solve your big problems.
