I explored that Intel link prior to posting my first question. I couldn't find anything related to my system's chipset (never mind that the identification utility doesn't work on Windows 7 x64).
There are no 3rd party firewalls, anti-spyware apps, etc on this system. It is a clean W7 x64 install. I do have McAfee Enterprise 8.7.0i and it is current on its DATs.
