AVG Free Reboots and Internet Security pop-ups are irritating

Sorry for the trouble, Anita.

Have you uninstalled AVG using its clear tool? If not, refer this article: http://support.avg.com/SupportArticleView?urlname=How-to-troubleshoot-issues-after-upgrade-to-the-latest-AVG-antivirus-product  to run AVG Clear and Remover tool which removes the traces of AVG completely. Note: Run AVG Clear tool first.

Use this link: https://www.avg.com/en-us/download.prd-gsr-free to download offline installation file of AVG Antivirus Free and check its status.

Share the screenshot https://support.avg.com/SupportArticleView?l=en&urlName=How-to-create-a-screenshot&supportType=home of the popup you received to check and assist you further.

After cancelling my AVG Internet Security subscription, the program is supposed to "revert to free". It wasn't performing and kept asking me to renew or upgrade, so i uninstalled the program.  Now, I'm faced with TWO VERY IRRITATING PROBLEMS

After uninstalling the AVG Internet Security, I downloaded the AVG Antivirus Free (I've been utilizing this since it first was available almost 10 years ago!).  But now, it keeps requiring a reboot and it's beginning to get irritating.  As I am typing this, the darn "Internet Security" pop-up popped up again!

HELP!! What to do!? What to do!?

Thank you for providing screenshot Anita,
The issue might be because of old/previous AVG Internet Security traces. In this case, I request you to remove AVG completely along with any previous traces using the AVG clear tool/AVG Remover tool and then do a fresh installation of AVG Free Antivirus. This will ensure that none of the previous traces of AVG are left on your computer and you have an updated version.
Please follow the instruction (http://support.avg.com/SupportArticleView?urlname=How-to-troubleshoot-issues-after-upgrade-to-the-latest-AVG-antivirus-product) to run AVG Remover tool and AVG Clear tool.
After the computer reboots, you can follow the instruction to download/install AVG Free Antivirus.
Best regards,
Alok.
