Note: To complete the unenrollment fully, the Symantec Protection Engine service will need to be restarted. If you plan to re-enroll the scanner, you can skip restarting and go straight to the last step.
If you do not plan to re-enroll the scanner, restart the Symantec Protection Engine service.
To enroll the scanner again, run the enroll.bat from SPE's installation directory.
