the report in Registry Cleaner shows "chinese signs". You find them at "Benutzer-Detailverlauf" (German version, I assume in the English version it is something like "user file process")
You will find them as "chinese" users. The report shows that these users are especially checking on which files had been opened and worked on in the last sessions. The number of "chinese users" popping up grow over time.
I am worried the system has been infected by malware, like trojans.
Are these "chinese users" unauthorized users ?
