Detalhes técnicos
Installation
Schleust die folgenden Eigenkopien in das betroffene System ein:
- %System%\winmsfws.exe
(Hinweis: %System% ist der Windows Systemordner. Er lautet in der Regel C:\Windows\System unter Windows 98 und ME, C:\WINNT\System32 unter Windows NT und 2000 sowie C:\Windows\System32 unter Windows XP und Server 2003.)
Autostart-Technik

Einschleusungsroutine
Schleust die folgenden Dateien ein:
- %System Root%\a.bat
- %User Temp%\1.reg
(Hinweis: %System Root% ist der Stammordner, normalerweise C:\. Dort befindet sich auch das Betriebssystem.. %User Temp% ist der Ordner 'Temp' des aktuellen Benutzers, normalerweise C:\Dokumente und Einstellungen\{Benutzername}\Lokale Einstellungen\Temp unter Windows 2000, XP und Server 2003.)

Solução
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
Im abgesicherten Modus neu starten
Step 3
Diesen Registrierungsschlüssel löschen
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 6
Diese Dateien suchen und löschen
- %System Root%\a.bat
- %User Temp%\1.reg
Step 7
Führen Sie den Neustart im normalen Modus durch, und durchsuchen Sie Ihren Computer mit Ihrem Trend Micro Produkt nach Dateien, die als BKDR_RBOT.BRU 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.
