Windows 7 has a presentation mode that can be leveraged by other applications to delay activity.

This request is for SEP antivirus scans to monitor for presentation mode being active and delaying start for example by 2 hours if it is. This could be implemented in such a way that SEP customers can chose whether or not they want presentation mode awareness active or not.
Symantec case is opened with our TAM: "04926934 - Win 7 Presentation mode and SEP scans"
