I would assume it is different some as partners delay patches and version updates till they QA them themselves. What affid no does yours say in the about area?
I remember this. It was a promo. Smth like: create acc on facebook & get MIS free for 6 months. Probably build with facebook logo not ready or they will never add this on release server.
To force the update you can try reinstalling the McAfee from AU server CLICK HERE and check you are getting the latest version (a try)
Before reinstalling the McAfee, you have to use the below McAfee Removal tool to remove the McAfee program followed by removing the McAfee from Control Panel if listed
