Windows 10 / Windows Defender - Virus and threat protection problem

For some time this information has appeared [photo below] and at the moment I do not know if there is any point in using AVG on Win 10, after removing AVG this disturbing black dot will disappear?
Be warned that I cannot see this information after opening AVG.


Edit
I uninstalled AVG, manually, with AVG remover and even with Revo, there is almost no trace of it, because the message on the left side of the photo is still shown, ie status unavailable [...] Open AVG applications and attention ... It starts

After uninstalling AVG, make a backup and then clean invalid registry entries and temp files with CCleaner =>

Additionally, download FRST compatible with your system version =>

perform a scan and list FRST.txt and Addition.txt as attachments.

Installing AVG again and uninstalling helped, now without any problems.

The black dot turned green
