Each McAfee product subscription is associated to the TWC email address that was initially used to download the McAfee product. To download a new McAfee product, you must use a unique TWC email address (a TWC email address different than the TWC email address that was used to download your original McAfee product).
When you have a unique TWC email, you can visit our Internet security support page to register your new software.
Once installed, the software will routinely look for new virus definitions and updates that may be available. If either are ready to be downloaded, the software will automatically implement those updates.
