Norton Family Tablet - Glitch

My son discovered a glitch with the Norton Family Tablet App that allowed him complete access to the internet in which he was able to search and download things onto his tablet.

I have the Internet Explorer blocked but as he describe he opened Internet Explorer and hit the back button three times which glitched the Norton App from blocking anything in which he was able to have complete use of the internet. 

I tried to report this to Norton at which I got a 'call back' and I couldn't understand the guy at all...Very bad English and heavy accent. Sorry.

Please fix this bug or tell me how I can fix it.
