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.

Step 5

Führen Sie den Neustart im normalen Modus durch, und durchsuchen Sie Ihren Computer mit Ihrem Trend Micro Produkt nach Dateien, die als WORM_VOBFUS.SMAE entdeckt werden. Falls die entdeckten Dateien bereits von Ihrem Trend Micro Produkt gesäubert, gelöscht oder in Quarantäne verschoben wurden, sind keine weiteren Schritte erforderlich. Dateien in Quarantäne können einfach gelöscht werden. Auf dieser Knowledge-Base-Seite finden Sie weitere Informationen.
