• New versions may include new features and compatibility with newly released operating systems or operating system updates (service packs).

A Subscription Renewal is a service that you purchase to continue to receive virus definition files and/or content filter lists that the service provides. When you renew your subscription, you buy the service that provides the virus definition files and/or content filter lists for 12 months. For help with subscription issues please see the Subscription Troubleshooter.
