Schritt 1

• Schließe alle offenen Programme und Internet Browser, damit keine Daten verloren gehen.
• Kopiere den gesamten Inhalt der folgenden Code-Box:
  

  Start::
  Unlock: C:\vms
  VirusTotal: C:\vms\VBoxVmService64.exe
  Unlock: C:\Program Files\qemu
  VirusTotal: C:\Program Files\qemu\Host Services x64.exe
  End::
           

• Starte nun FRST und klicke direkt den Reparieren Button.
  Wichtig: Du brauchst den Inhalt der Code-Box nirgends einfügen, da sich FRST den Code aus der Zwischenablage holt!
• Das Tool führt die gewünschten Schritte aus und erstellt eine fixlog.txt im selben Verzeichnis, in dem sich FRST befindet.
• Gegebenenfalls muss dein Rechner neu gestartet werden.
• Poste mir den Inhalt der fixlog.txt mit deiner nächsten Antwort.
