This is crazy. Comodo CIS Premium is uninstalled, but it continues to put programs in containment!
And it gets even better… it puts the uninstaller in lockdown, which means I can’t solve this problem if I’m not a computer scientist!
Because there is something new in addition… even in forced mode, Revo Uninstaller cannot uninstall what remains of Comodo CIS which self-confines
PS 
Even more strangely, by chance I discovered that :
Version ciscleanuptool_x64. .3.3.0.95 did not work or was confined.
While version CisCleanupTool_x64_3.1.0.55 worked fine… (Not confined)
I’m speechless!
