What does “W11332244H9900A0420-8MRTR8W5” mean?

The universal key, “W11332244H9900A0420-8MRTR8W5” has a secret meaning to me. Looks like a mystery to me. Do I need to use it before my expiration date for my subscription for Avast! Free Antivirus expires on March 8th this year? Can you tell the universal key, “W11332244H9900A0420-8MRTR8W5” is used for, please?
