On my desktop with XP with FireFox (Yahoo edition) ... I see an unwanted tool bar and an accompanying search screen . The toolbar has elements “Web Images Videos News More and Results by bing”. The search screen shows an icon of a magnifying glass and the word “entrusted.” When I click View/Toolbars I see one listed as “entrusted Community toolbar” but it is unchecked.

Are the toolbar and search screen related? How can I delete and remove them?

Thanks.
