If you want to remove the Vuze toolbar for Safari, just go to Finder and click on Applications, then Toolbars, then Vuze.  In that folder, double click on "uninstall".  If you don't see the Toolbars folder in Applications, check under the main Applications folder instead of the user folder: Click on your hard drive under Devices in Finder, then Applications, then Toolbars.

You might need to provide the administrator password to complete the process.

Also, if that process doesn't work then the following might help as well:

Go into library, then into applications support and then into the Conduit folder.
Remove toolbar and toolbarbundle from the conduit folder

Or

Go to /Library/InputManagers and delete the folder "CTLoader". Note that this isn't in your user folder.
