Have you looked at chromes add-on's and extensions? I don't use chrome. I use Firefox myself but I assume they must have something along those lines. Clear your browser cache as well.
There's a search engine/browser add-on called Delta that snuck onto my PC a while ago. It had hidden it's self away in the the add-on's of firefox if I recall correctly. Up until I managed to remove it my webpages would always open up as Delta no matter what I did.
Just the fact that some geniuses were laughed at does not imply that all who are laughed at are geniuses. They laughed at Columbus, they laughed at Fulton, they laughed at the Wright brothers. But they also laughed at Bozo the Clown.
