I updated a program that I use called Any Video Converter, but I accidentally missed unchecking one of the PUPS during installation that makes Yahoo my primary search for all my installed browsers. I used Revo Uninstaller to remove the Yahoo instillation and it fixed all my browsers except Firefox. I have went into about:config and changed everything that I saw from Yahoo back to Google, but it still uses Yahoo when I highlight something on a page or use the address bar to search for something.
