had this problem after accidentally downloaded the yahoo toolbar along with an adobe product. Firstly, tried to remove it control panel in add/remove programmes but it refused to uninstal. Since then was told by technicians of my ip to use Revo uninstaller the free ed. Next step was go to tools then options. On the general tab, at the bottom you will find manage-add-ons. under search provider do not want. f yahoo is still there disable it. Also go to internet options in control panel and set up there too. Be sure to find and tick the option that other search engines cannot change yours. Be sure to set the appropriate home page.

Thanks so much, cor-el! This solved the issue. And your instructions were clear and to the point. I checked my installed programs and don't have any that I do not use, or that would cause this issue, as I am VERY careful with what I install and VERY picky about what I let linger on my computer.

Thanks so much! Worked! (For some reason, an error occurs when I click 'Solved It'. I apologize.)

P.S. Sometimes, it will use 'I'm Feeling Lucky' instead, i.e. it'll take me straight to a related web site. And I entered the link for regular search.

You're welcome
