It seems to be related either to the Vuze torrent client or to some Conduit.com toolbar you might have installed.
Was it the Vuze client:
Open a new Finder window.
Click on Applications.
Open the Toolbars folder.
Open the Vuze folder.
Double click on Uninstall.
Regarding a Conduit toolbar, go to /Library/Input Managers, move the CTLoader bundle to the Trash, restart the Mac afterwards.
Also, go to your Library folder/Internet Plugins and look for anything CT Loader related there and delete it.
