AVG is saying that internet security expires in 19 days but I renewed AVG ultimate recently
Margaret,
I understand the situation. Don’t worry I'll help you with your issue.
I suggest you to re-login into your AVG Dashboard with your AVG My Account Credentials.
Please follows the steps below to re-login:
1. Please click on your Email Address in your AVG Dashboard and then select Leave this Network
2. Click Connect at the top-right of the screen, then click Log into the account again.
3. Type your email address and the password, then click Log In.

These steps should fix the issue.
