Defense Center entfernen


Was ist Defense Center?
Defense Center ist ähnlich zu Protection Center und Your Protection. Defense Center ist eine weitere Rogue-Malware in Form einer gefälschten Scan-Software, die mittels eines sog. Trojaners in den PC eindringt und dem Benutzer weissmacht, den PC nach Malware abzusuchen. Diese Software (Defense Center) ist ein Fake und selbst eine Schadsoftware und sollte nicht gekauft werden.

Da solche Software wie Defense Center sich gegen jede Entfernung wehren wird und Defense Center oftmals noch Rootkits mitinstalliert, sollte eine Neuinstallation des Systems in Erwägung gezogen werden.

Verbreitet wird Defense Center nicht mehr ausschliesslich über 'dubiose Seiten' für Cracks, KeyGens und Warez, sondern auch seriöse Seiten werden zunehmend für die Verbreitung dieser mißbraucht (Drive-by-Installation).

Defense Center entfernen


Abgesicherter Modus zur Bereinigung

• Windows mit F8-Taste beim Start in den abgesicherten Modus bringen.
• Starte den Rechner in den abgesicherten Modus mit Netzwerktreibern:
  
  

• Starte einen vollständigen Scan mit Malwarebytes Anti-Malware

Achtung: Diese Fake Software wird versuchen, den Einsatz von Malwarebytes zu verhindern. Benenne das Setup vor dem speichern in etwas anderes um (z.B. Herbert.exe).

Falls es vorher nicht funktioniert hat, sollte das Setup jetzt starten.

Wenn das Programm nach der Installation nicht starten sollte, dann benenne die "mbam.exe" in "herbert.exe" um und versuche es erneut.

Sollte MBAM trotzdem nicht starten: Malwarebytes Anti-Malware startet nicht

Defense Center immer noch nicht entfernt?

OTH - OTHelper - Kill All Processes


Mit aktualisiertem (!!) Malwarebytes Anti-Malware nach Ausführen von OTH nochmal QUICKSCAN ausführen.

Weitergehende Prüfung

Das System könnte noch nicht vollständig sauber sein.

Daher unbedingt ein Thema erstellen: Für alle Hilfesuchenden! Was muss ich vor der Eröffnung eines Themas beachten?

Nicht vergessen mit OTL Logfiles....
