Norton Remove and Reinstall removes most Norton Products from your system, plus it downloads the latest version of you Norton product, and reinstalls the latest version of your Norton security product. If you already have the latest version of Norton AntiVirus, Norton Internet Security, or Norton 360, the Norton Remove & Reinstall tool reinstalls the same version of the Norton security product on your computer.
Norton Remove and Reinstall should be used only if you have tried to uninstall the Norton program using Windows Add/Remove Programs and that did not work.
