"why has my behavior shield been turn off may times"

Hi John,

We're glad to look into this & help you.
Sometimes, this might happen if few services are unable to initiate or due to the presence of other antivirus on your computer.
In this regard, please check & remove if there are any other antivirus installed on your computer.
If there is no other antivirus installed on your computer, please repair AVG program once to ensure that all the services are running fine.
