Mary, I am sorry for any inconvenience caused.
I'd request you to download and run AVG Clear tool as per the instructions in this article to detect and remove the latest version of AVG completely. Then click on this link on how to reinstall AVG Anti Virus free.
After running my last virus scan a couple of days ago my AVG Free is unaccesable. I get a screen with in red that my Internet security has expired. I tried several times to delete and reinstall AVG free and everytime it seems to work fine until I have to restart my computer and than the screen with the message is back. I've used AVG removal tool to remove AVG, but it says it can't find any active opponents of AVG. What can I do to get AVG free back running well?
The small AVG icon on my taskbar states that my system is protected, but whenever I click on it I get to the screen with the "Internet security has expired".
Computer runs on Windows 8.1
