why we can't clear the  protection history like other programs ?

I suggest to be enabled to clear it and deleting files from quranteen

Exit TM

Go to C:\Program Files\Trend Micro\UniClient\plugins and delete EventLog in plugins folder.

Go to Local C:\ Program Data\Trend Micro\AMSP and delete "quarantine'

Restart TM
