xxx: there is such a beast, "coach", which in English translation means "reboot". he steals quietly and throws on unsecured documents and eats them. Especially he likes to steal before lunch and at the end of the working day, when work in unsaved documents has been done a lot and their loss is irreparable. You can only fight the scam by frequently saving documents, then it is offended and goes to other computers.
He is your beast.
