We can't take Bing off your computer.

If you put Bing on your computer as the homepage, and you use Internet Explorer 8, click this link: http://www.fettesps.com/how-to-uninstall-bing/

If you put Bing on your browser as a Toolbar, do the following:
Click your start button (It will vary, depending on your OS).
Go to Control Panel.
Click on Add/Remove Programs (On IE8, it will say Programs, and underneath it 'Uninstall a program'.)
You should see a list of things installed on your computer. Look for the Bing Toolbar.
Click on it, then click uninstall, and follow the instructions.
