  Lösungen

Mindestversion der Scan Engine: 9.850

Step 1

Für Windows ME und XP Benutzer: Stellen Sie vor einer Suche sicher, dass die Systemwiederherstellung deaktiviert ist, damit der gesamte Computer durchsucht werden kann.

Step 2

Dateien erkennen und deaktivieren, die als Trojan.Win32.DELF.WLDC entdeckt wurden

[ learnMore ]
  1. Für Windows 98 und ME Benutzer: Der Windows Task-Manager zeigt möglicherweise nicht alle aktiven Prozesse an. Verwenden Sie in diesem Fall einen Prozess-Viewer eines Drittanbieters, vorzugsweise Process Explorer, um die Malware-/Grayware-/Spyware-Datei zu beenden. Dieses Tool können Sie hier.
    2. herunterladen.
  2. Wenn die entdeckte Datei im Windows Task-Manager oder Process Explorer angezeigt wird, aber nicht gelöscht werden kann, starten Sie Ihren Computer im abgesicherten Modus neu. Klicken Sie auf diesen Link, um alle erforderlichen Schritte anzuzeigen.
  3. Wenn die entdeckte Datei nicht im Windows Task-Manager oder im Process Explorer angezeigt wird, fahren Sie mit den nächsten Schritten fort.

Step 3

Diesen Registrierungswert löschen

[ learnMore ]

Wichtig: Eine nicht ordnungsgemäße Bearbeitung der Windows Registrierung kann zu einer dauerhaften Fehlfunktion des Systems führen. Führen Sie diesen Schritt nur durch, wenn Sie mit der Vorgehensweise vertraut sind oder wenn Sie Ihren Systemadministrator um Unterstützung bitten können. Lesen Sie ansonsten zuerst diesen Microsoft Artikel, bevor Sie die Registrierung Ihres Computers ändern.
