Safari Browser (I don't know why using it) is registered as the search app. to run.
You will have to find it in registry and remove it, most likely Hkey_Current_User or Hkey_Current_Config. Always backup registry first. Make sure you only delete it where it references Search App.
Personally I would uninstall and remove Safari altogether, no browser is faster than Seamonkey (new Netscape, still Mozilla) or offers better security.
