About license key

A license key is a sequence of bits that you can use to activate and then use the application in accordance with the terms of the End User License Agreement.

A license certificate is not provided for a key that is added under a subscription.

You can add a license key to the application by either applying a key file or entering an activation code.

The key can be blocked by Kaspersky if the terms of the End User License Agreement are violated. If the key has been blocked, you need to add a different key to continue using the application.

There are two types of keys: active and reserve.

An active key is a key that is currently used by the application. A trial or commercial license key can be added as the active key. The application cannot have more than one active key.

A reserve key is a key that entitles the user to use the application, but is not currently in use. At the expiry of the active key, a reserve key automatically becomes active. A reserve key can be added only if the active key is available.

A key for a trial license can be added only as an active key. It cannot be added as the reserve key. A trial license key cannot replace the active key to a commercial license.

If a key is added to the list of prohibited keys, the application functionality defined by the license used to activate the application remains available for eight days. The application notifies the user that the key has been added to the list of prohibited keys. After eight days, application functionality becomes limited to the functionality level that is available after license expiry. You can use protection and control components and run a scan using the application databases that were installed before the license expired. The application also continues to encrypt files that had been modified and encrypted before license expiration, but does not encrypt new files. Use of Kaspersky Security Network is not available.
