Moved to VSE for faster support.
If you validate the version of the binaries, you'll establish whether it's a reporting bug or if the engine didn't upgrade -
The x64 engine exists in a subfolder from the x86 engine.
C:\Program Files (x86)\Common Files\McAfee\Engine\x64
The binary is called Mscan64a.dll, check it's properties to verify the version.
And if it's a reporting bug, we typically treat those as low severity issues - that tend to fall to the bottom of the list when identifying things to fix. Especially so if there's a workaround for causing the values to report accurately (like rebooting).
