How to Reinstall Norton 360

If Norton 360 was previously installed on your computer or has become corrupt, you may need to reinstall the software. The Norton installation software removes early traces of the software when it installs a new version, so Symantec (Norton's developers) suggest downloading the latest version of their software to begin the installation. You may need to re-enter your serial number during installation.
