the Defence+ put "MsMpEng" in sand box...

The defence+ isolates “MsMpEng” (Microsoft security essential )every time the system starts. later i have run a “Online ook up” on the sandbox control panel for “MsMpEng”, the result is"Safe",and it says “the safe files have been moved to your local COMODO certified files database”,but at the next reboot, MsMpEng is isolated again. Am i experiencing a BUG ???

Try the suggestions described in App. is not working correctly, but does not seem to be s/boxed. What to do? [v5].
