Trojaner-Board - Logfile + cshelper.exe

Hallo zusammen,

hab heut etwas gefunden, dass mich stutzig machte - cshelper.exe.

- Googeln hat mich nicht viel weitergebracht - könnte laut McAfee-Seite* evtl von einem Programm namens CopySafe PDF kommen, von dem ich noch nie was gehört hab und das auch nicht bei mir installiert ist.

- Laut Virustotal stuft sie nur Fortinet als 'suspicious' ein:

Hab auch mal malwarebytes über den PC laufen lassen, der hat keine infizierten Objekte gefunden.

Wie lautet die Diagnose?

Vielen lieben Dank im voraus!
