Warning from AV software about kill.exe

I'm running git under Win7 64. As I selected "Repository|Visualize all 
branch history" in the git gui, my AV software (Trustport) trapped the 
bin\kill.exe program for "trying to modify system global settings (time, 
timezone, registry quota, etc.)"

Does anyone know the details of this process and what it's function is? 
First time I've seen it, though I'm a relatively new user.

Cheers,
