"disconnected or disabled" alerts

Hi,

 

Could someone please explain this alert:

 

Norton Safety Minder's web browser monitoring component is either disconnected or disabled. Please restart the web browser or restart your computer. [PC02]


- What is causing this alert?

 

- What exactly does this mean? Is all site blocking turned off at this point and they can go anywhere they want, even to porn sites?

 

- What am I supposed to do to prevent this from happening?

 

- If I log into the kid's account, what evidence should I look for that Norton Online Family is being tampered with?

 

The kid's account is a standard account, and they do not know the password. Can they still disable the monitoring component?

 

Thanks.
