I have done a Restore on my PC and find I now have this toolbar from my service provider, and I can't get an answer from Orange. This sort of thing really angers me, and if I didn't have a contract, would be enough to make me switch. Richard Heckstall-Smith
Orange has an article in its knowledge base called: How to uninstall the Orange search toolbar. You can find it by searching Google for "Article ID: kb3247" or clicking here. Do the removal with only one browser window open, and reboot your PC afterwards.
