I need a clarification after the renewing of my internet security

In the menu "about" I saw a note which was saying that I have to clarify the expiration date 16 Jan 2018. What does it mean

Hello George,

I understand your concern. On checking your account, you had an active subscription to AVG Internet Security which was valid until 1/16/2018. Then you have migrated the program to AVG Internet Security Unlimited and it is valid until 1/16/2019. You need to reactivate the program to get the correct expiry date. Please open AVG Internet Security, click on the Home icon at the top left corner of the interface to open AVG management console (formerly known as AVG Zen). 
Follow the article http://support.avg.com/SupportArticleView?urlname=Activate-AVG-Zen-Protection-Performance-or-Ultimate to activate AVG Internet Security Unlimited and check the expiry date in AVG Internet Security > Menu > About > Subscription.
