SecProxy.exe from BaseShield App Store.(C:\Windows\system32\BaseShield\BaseShield\SecProxy.exe) performed operations on the following processes belonging to Symantec Endpoint Protection:

C:\Program Files\Symantec\Symantec Endpoint Protection\SmcGui.exe

C:\Program Files\Symantec\Symantec Endpoint Protection\Rtvscan.exe

C:\Program Files\Symantec\Symantec Endpoint Protection\Smc.exe

C:\Program Files\Common Files\Symantec Shared\ccApp.exe

C:\Program Files\Common Files\Symantec Shared\ccSvcHst.exe

The operations it performed include "Memory Free", "Thread Resume", "Memory Write", "Memory Allocation".

I don't know why any app, let alone BaseShield would have to access and modify the memory of a program totally unrelated to it.
