Have license till oct 2019 and march 2019. why AVG puts me on trail version suddenly?
Why do I need buy or renew when my license is for 2 years.

Hello Sridhar,

I apologize for the inconvenience.

I see that you have AVG Internet Security valid until 9/30/2019. Please open AVG Internet Security > My AVG > My Subscription > click Logout (if you have that option) > Enter the license and click ok

If you face any difficulties, please let me know to assist further.
