This policy setting allows you to configure security intelligence updates according to the scheduler for VDI-configured computers. It is used together with the shared security intelligence location (SharedSignaturesLocation).

If you either disable or do not configure this policy setting, updates occur whenever a new security intelligence update is detected at the location that is specified by SharedSignaturesLocation.
