Je suis infecté: Win32/Adware.Virtumonde.O

Bonjour a tous,
Je suis tout nouveau et j'ai lu beaucoup sur ce forum. Il semble y avoir beaucoup de bonnes personnes.
Comme mon message le dit, mon ordi est infecté depuis près d'une semaine et j'ai essayé plein de chose mais l'infection perdure.
Mon antivirus est NOD32. J'ai passé spyboot, adaware, SpyCatcher, RegCleaner.
Mon antivirus me laisse cet avertissement:

Virus détecté en mémoire: probablement une variante de Win32/Adware.Virtumonde.O application. Ce fichier peut être supprimé. Assurez-vous d'avoir sauvegardé vos données avant le nettoyage. Aucune action ne peut être appliquée à une infiltration en mémoire. Infection de la mémoire système originaire du fichierC:\WINDOWS\system32\vtstr.dll.
Je n'arrive pas a enrayer le virus. Les programmes mentionnés ci-haut détectent des intrus, les enlèvent mais ils reviennent toujours.

J'espère que quelques uns d'entre vous pourront me venir en aide.
