usually these stupid ie add on's can be deleted using your Add/Remove Programs option. If it's not there, try your ie preferences. If you still can't find a way to turn it off...
It my be spyware if its not an IE add-on. If that is the case download Ad AwareSE or some other spyware scan utility. Ad Aware is at lavasoft website or download.com. Choose full scan for the first session. | :| |
Don't use the right-click menu. Use the main menu: View->Toolbars
The right-click menus for 3rd-party applications are not controlled entirely by Windows. The makers of that toolbar had to have programmed those items into the list. If they failed to include an option you wanted, tough luck.
