Free AVG Antivirus is causing my PC running windows 10 to lockup

 

Original question:
While using my computer I randomly have  this error message:

The connection is not private
NET:ERR_CERT_AUTHORITY_INVALID

While using any browsers and safe programs the above error will pop up and lock up my computer. In order to  clear this error message. I have to restart my computer then, my computer works fine for usually a extended amount of time before the error causes another computer lockup. I contacted Microsoft support about this error/problem and a support post stated that Microsoft Engineering found that AVG Antivirus is causing this error/problem and the cure is to uninstall AVG and not use it. Please let me know if AVG has a fix for this error so I am not forced to stop using AVG Antivirus
