Norton Uninstallment Issue

I am not sure what happened, but it has been going on for a while now. Our Norton account expired and was not renewed. However, it is still timing out on my computer, kicking me off my user. I can then switch to the other user, but it kicks me off that, too, a little later. If I try to uninstall Norton using the login to get onto my account it says this device is part of a different account. So far, what it looks like is that Norton does not register that this computer has Norton downloaded, but it still seems to be blocking me from using it for over some designated amount of time. I have tried to re-download Norton, but after I tell my computer to run the program it does not complete download or something like that, as I can only find the icons for installing norton and the file for uninstalling it.
