When it comes time to upgrade your Norton products, having to uninstall every version before installing the new version can be time consuming but isn't always necessary. Whether you need to uninstall first depends on whether you're installing an upgrade or a completely new version. Symantec, the maker of Norton, attempts to simplify the uninstall process by providing you with a removal tool that completely erases all traces of Norton on your system. www.norton.com/setup
