Hello, Robert.
Thank you for reaching us with your concerns. I see that you have an active AVG Internet Security (1 computer) license valid till 5th Dec 2018 which was renewed on 26th Nov 2017. The expiry date is correct as per your records.
Ah the date is in American… Thank you! I can stop worrying now 
After spending a few hours trying to get the new update to the gui to run properly, I have noticed that the "Next billing date" in the Subscriptions says 12/05/2018.
Is there any reason it is wrong?
I did have to manually renew my licence as I was informed via automated email that there was an issue extending the then current licence.
