Windows protected you when it saw you remove Norton, it could not then restore your system to a previous good point. So it cancelled all.
You should be able to get it back to life providing all is well in the registry.
Go to control panel/system/performance/file system/troubleshooting and click to disable restore system. reboot computor.
Reinstate restore - reboot and leave to see if it begins to create new points.
Sometimes you have to do the process more than once to get it to work
