I was trying to find a solution for this also. I've been using TP for a number of years, and just changed my Laptop, now this Icon appears where I don't want it, and I don't even use that feature!
A solution seems to be to run the following in a CMD window under Administrator. I suspect you'd have to run this every time they update their software. I guess you could stop this for now until they Fix it properly. On refreshing your 'Devices and Drivers' Folder the vault does vanish.
Run CMD as Admin:
"C:\Program Files (x86)\Common Files\McAfee\Installer\mcinst.exe" /uninstall /longpath "C:\Program Files\McAfee\MAT\matmain.inf"
Its sad that they didn't fixed this yet and that they don't listen to their customers. I thought someone from McAfee would still give us some feedback in this thread, but I guess right now are too busy splitting company into two separate entities.
To solve the problem of icon
First of all go to control panel then uninstall/change a program then as an administrator click yes .
Then mcafee wizard will open then choose file lock check box among the three options then click ok , as given .
At last restart your PC and the problem is solved . Trust me it really worked with uninstalling mcafee.
I was facing same problem too
