Rapport hijackthis

Bonjour,
n'arrivant plus à me connecter à msn pour cause d'erreur lors de la synchronisation de l'horloge avec un serveur internet, et après avoir tout essayé, il semblerait que ce soit du a un virus, que MSNfix m'a detecté, mais est incapable de nettoyer car il ne retrouve pas les fichiers.
Mon antivirus (avast! 4.8) et mon anti malware (malwarebytes) ne trouvent rien d'anormal lors du scan.
Voici un rapport hijackthis, quelqu'un pourrait il m'aider ?
