Norton Utilities Boot Time Scan Disk

I'm running Norton Utilities 16 on Windows 10. I selected disk doctor to run at boot time. When of boots I get a jobmanagerlast error Cjobmanager:: checkout error xml file corrupted press any key etc. When I press any key get a blue screen while it bad_system config info. Reboots and does same again.

how do I fix this.

i can get to the command prompt. In days of old I'd fix this by editing autoexec.bat
