trends daily pop up regarding pua threat cannot quarantine

Hello, I have been having Trend popping up with the 'threat' below for "PUA.MacOS.JAILBREAK.MANP" several times a day. I know what is a PUA and have searched through my applications in my Macbook for PUAs and cannot find any relevant ones. I've checked my browser (Chrome) for add-ons and there are none.

I have tried to manually delete that file associated with the PUA - it is the "MobileDeviceUpdater" (unix executable) in the MacOS sub-sub-sub folder. I have tried to delete this sub-sub-sub folder but cannot be deleted. 

I have tried running command "rm (dropfile in here)" - also to no avail. 

I read that this MobileDeviceUpdater is somehow related to iPhone OS update or something?

Any thoughts or help to remove this PUA threat that keeps popping up in Trend scan?
