- %System Root%\AUTORUN.INF
- %User Temp%\ieA236.tmp
- %System%\aktwkss.dll
(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.. %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.)
Solutions
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
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 4
Diesen geänderten Registrierungswert wiederherstellen
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.
- In HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Folder\Hidden\SHOWALL
- From: CheckedValue = "2"
To: CheckedValue = ""1""
- From: CheckedValue = "2"
Step 5
Diese Dateien suchen und löschen
- %System Root%\AUTORUN.INF
- %User Temp%\ieA236.tmp
- %System%\aktwkss.dll
Step 6
Durchsuchen Sie Ihren Computer mit Ihrem Trend Micro Produkt, und löschen Sie Dateien, die als TROJ_AUTORUN.BCA 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.
Step 7
Diese Datei über eine Sicherungskopie wiederherstellen Nur Microsoft basierte Dateien werden wiederhergestellt. Falls diese Malware/Grayware/Spyware auch Dateien aus Programmen gelöscht hat, die nicht von Microsoft stammen, installieren Sie diese Programme auf Ihrem Computer bitte neu.
