NIS 2014 V21.0.1.3: NIS.exe high CPU usage during first 60-90 seconds on startup

This applies to Windows 8 x64 Professional and Windows 7 x86 Professional, NIS 2014 V21.0.1.3.

 

On system startup, NIS.exe run 45-55% utilization for 60-80 seconds after the desktop appears.  This is a constant high CPU usage for the 60-80 second period.  It is the SYSTEM component NIS.exe.  It is 100% repeatable and occurs on all my computers.  NIS 2013 did NOT have this problem. 

 

Turning off Enable Boot Time Protection and Early Launch Anti-Malware Protection and SONAR does not change this situation.
