Trail expired notices won't go away

Hello Dan,
I'm sorry to hear about this. I have sent you an email, please follow the email instruction to connect with us remotely. We will check with your installed AVG program and we will help you to activate/install AVG PC Tuneup.
Best regards,
Alok.

Hello Dan,

I am sorry to hear that. Please let me know what type of AVG licenses you have running in your PC? Please share a screenshot http://support.avg.com/SupportArticleView?urlname=How-to-create-a-screenshot 
of the popup notifications to check and assist you better.

I have a paid subscription but the free trial notices are still coming up with a number of things that 'need fixing' trying to sell me a subscription. Why don't the notices stop, how to get rid of them and if there are 'fixes' required, why is the paid version not fixing them already?

Dan, Have a look @ this AVG article (http://avgclick.me/getscreenshot). For your info, just in case that you are unaware, you can post the screenshot here in your topic. Click on 'Answer' & then click on the 'Image' [mountain symbol] & follow the instructions.

Dan,

Thank you for getting back to us with the screenshot.  I can see that you are having paid AVG PC Tuneup. Since you are still getting the pop ups to buy more products, it might be because the AVG program is not activated yet. Please follow the instructions in this article http://support.avg.com/SupportArticleView?urlname=How-to-download-and-install-AVG-PC-TuneUp to activate AVG PC Tuneup and check the status.

If you face any difficulties, please contact us back.
