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

Durchsuchen Sie Ihren Computer mit Ihrem Trend Micro Produkt, und löschen Sie Dateien, die als Trojan.HTML.PHISH.QURAAOOIUE 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.
