There is nothing with the AVG application. I've been using it for a very long time and there were no threats or notifications from other security applications saying there is a risk.
The software ByteFence might be providing false information about an antivirus that is used by millions.
I've double checked and scanned the AVG Free Antivirus and it was marked as being more than safe.
Note: Also download AVG from its official website or other trusted sites.
