Hello Marga,

I understand the inconvenience. Please repair AVG Internet security/ AVG Antivirus free http://support.avg.com/SupportArticleView?urlname=How-to-repair-AVG from the control panel and then check the status. If the issue persists, please share a screenshot of AVG Interface and let me know the version to assist further.

Marga,
I would like to appreciate your efforts to repair but I regret to hear the issue persist. I would request you to uninstall AVG completely and re install it. Click on this link http://support.avg.com/SupportArticleView?urlname=How-to-uninstall-AVG for steps on how to uninstall AVG.
Then visit this web page https://www.avg.com/en-us/download to download and install AVG.
