MVT is probably running ahead of itself and giving erroneous information. It's happened before. If SecurityCenter isn't green and states it is protecting I would contact Technical Support directly. It's free by phone or online chat and linked under Useful Links at the top of this page.
You will automatically get the latest engine and DAT with auto-updates as long as your subscription is current. Note that if you get your software from your ISP, PC maker or another 3rd party, there is a chance that they themselves haven't yet adopted an upgraded version.
The reason I add that is because the latest version uses a different engine and no DAT's so updates differently.
Thanks for that, I'll bear that in mind about MVT jumping the gun. My Security Centre has the green flash showing on it.
Please check the version of the Mcafee Software that you have installed. If the version of Mcafee Security Center is 11.6.xxx then you product are already running with latest version of engine.
