Then I would just uninstall it. Do you have 'spanner' icon? If you do, one of the options on that will be 'uninstall'.
Otherwsie you can go to control panel/programmes and uninstall it from there. I'm assuming you're running an MS OS, if not perhaps you could specify nad one of the computer boffins will probably be able to help you. Good luck - I know how irritating those things can be.
