Can't connect to internet / Can't uninstall Norton Online Family

A few weeks ago on the first evening back from an overseas trip, my son was trying to do late homework. He needed me to bypass theNorton Online Family to let him continue his work. I ignored the need to upgrade, as this was my first night back and it was late, but only briefly got connected to the internet. Since then, I can see the internet signal through wifi or cable but cannot connect. I have tried to uninstall Norton Online Family but it just stalls after attempting to log-in. Norton On-line family was a great tool but this is frustrating. Thanks
