Lösche anschließend manuell folgende Dateien:

C:\WINDOWS\d3hc32.dll
C:\WINDOWS\system32\jrbce.dll

und leere auch den Papierkorb.

Folgende Dateien solltest Du mal online bei http://virusscan.jotti.org/ überprüfen:

C:\WINDOWS\system32\d3al32.exe
C:\WINDOWS\System32\nvraidservice.exe

Oder noch besser, Du machst mal einen Scan mit eScan (siehe Signatur - Anleitung genau beachten !) und postest anschließend, was gefunden wurde.
Öffne dazu die mwav.log -> Bearbeiten -> Suchen -> infected oder tagged eingeben -> Weitersuchen -> Treffer markieren/kopieren und ins Forum übertragen.

Poste auch ein aktuelles HijackThis-Log nachdem Du die Einträge gefixt hast und mindestens einmal gebootet hast...
