App lock dilemna

I have the Norton security on my android phone, and the other day, the Norton app lock will not allow me into my settings or provide web protection.  I have tried and tried to uninstall, but it will not respond to that command.  Norton has been absolutely no help.  I have chatted with several agents who tell me they cannot help.  Please advise as to how to remove this app lock from my phone!  Thank you!!!
