.....Seriously - DON'T ASK......! This is a 'rogue' thing which either installs itself, or (if you don't watch out) gets installed with other programmes you download, many of them via the Yahoo links. If you don't UNCLICK the option to include it, you're lost! It CAN be uninstalled , but it is long and tiresome to do.....I've just spent all morning trying, and I'm still not sure if it's completely gone! It changes your search engine, installs itself and otherwise bores you! The instructions are complicated and difficult to uninstall it, and never garanteed to work. You can try this, or one of the other ones on Google (videos).... https://www.youtube.com/watch?v=wehJK8Ntd5k Good luck!
