Hallo Ihr Lieben,

da unser Computer seit gestern nicht mehr funktioniert und beim Öffnen nur noch der Hinweis auf das Vorhandenseins eines Trojanischen Pferds erscheint, habe ich einen Quickscan mit Malwarebyte durchgeführt und sage und schreibe 33 infizierte Objekte gefunden.

Das Logfile von Malware lautete:

Also der Trojaner ist trotz dieses Scans immer noch vorhanden. Zumindest erscheint beim Starten des Computers immer wieder das gleiche Fenster von Avira das auf ein trojanisches Pferd hinweist.

Ich hoffe, Ihr könnt mir weiterhelfen.

Wäre über eine baldige Antwort echt sehr dankbar.

Schonmal vielen Dank im Voraus !

Art des Suchlaufs: Quick-Scan

Hallo und

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

Danach OTL:

Systemscan mit OTL

Lade Dir bitte OTL von Oldtimer herunter und speichere es auf Deinem Desktop

• Doppelklick auf die OTL.exe
• Vista User: Rechtsklick auf die OTL.exe und "als Administrator ausführen" wählen
• Oben findest Du ein Kästchen mit Output. Wähle bitte Minimal Output
• Unter Extra Registry, wähle bitte Use SafeList
• Klicke nun auf Run Scan links oben
• Wenn der Scan beendet wurde werden 2 Logfiles erstellt
• Poste die Logfiles hier in den Thread.
