Virus : win32:adware-gen

Bonjour,

Cela fait 2 semaine que j'essai par tout les moyens de supprimer le virus win32:adware-gen mais sans succès.
J'ai suivi les différentes étapes que j'ai pu trouver sur les forums. A savoir, j'ai fait des scans avec Avast, Spybot, Ad-Aware, CClaener et suivi les instructions mais rien y n'y fait.
Ci-dessous le résumé de HijackThis pour quelqu'un puisse m'aider.
