Hi
You could try one thing, where you can delete the scheduled task that was added in the scheduled tasks.
Restart the computer, and then try to schedule a scan
For instance, after deleting the scheduled tasks for the earlier one, create a new one from your Norton program for the next 5 mins, if it works, then change the scheduled scan as per you want it
Or else, if that does not work then you need to uninstall and reinstall the Software.
