Hallo zusammen, auf dem Laptop meiner Freundin ist seit einiger Zeit ein starker Leistungsverlust festzustellen. Mein Verdacht waren gleich irgendwelche Backdoor-Aktivitaeten, deshalb gleich die Logs gefahren.

Hallo und :hallo:

Bitte routinemäßig einen Vollscan mit malwarebytes machen und Log posten.
Denk daran, dass Malwarebytes vor jedem Scan manuell aktualisiert werden muss!

Falls Logs aus älteren Scans mit Malwarebytes vorhanden sind, bitte auch davon alle posten!
