Found this article on Security Week. I suggest reading it if you aren't current on your nVidia drivers.

"Graphics card maker NVIDIA on Saturday quietly released a driver update (version 310.90) that fixes a recently-uncovered security vulnerability in the NVIDIA Display Driver service (nvvsvc.exe)."

Just downloaded the latest 314.07 drivers.

Not installed yet, but i don't expect problems, i never had any with driverupdates.

 

Just inspect carefully your FSX-NvidiaInspector settings afterwards: there are usually one or two things changed!
