Yahoo has taken over my Safari
I believe this happened when I downloaded a YouTube converter - it installed something that changes my browser to Yahoo, even though I have repeatedly set Google as my default browser in my Safari preferences. When I click on the new tab button, Google does come up as my "home page", that's not the issue. It's when I attempt to do a search right from the browser window at the top of the screen, my search results come up in Yahoo.
I've seen similar topics posted in the forum, but with no concrete fixes. How do I fix this so that Google is my default browser when I do a search in the top browser window?
Many thanks for any help!
