I try it on my computer and it works and successful activate the Avast free antivirus until 2038.

Still not believing? See the following picture. The Avast anti-virus in my computer active until January 19, 2038, 10:14:07 AM (active for 27 years).

Here the Avast License Key: W6754380R9978A0910-4TZ59467

Note: When I tested this key, Avast does not block these licenses. The Avast license key can be used on Avast free antivirus only and you can use the Avast free for non commercial uses only. Use the license as your own risk because there is no guarantee Avast would not block the license in the future.
