Password Protection Turns OFF Automatically

Hello,
AVG is telling me the Password Protection is OFF and I should switch it ON.
I switch it ON, but then after a while, not sure when, it switches again to OFF automatically.
What is controlling this AVG setting? I'm not switching it OFF, it does it on its own. 
Regards
