Besoin d'aide pour log hijackthis

Bonjour,
mon pc a été infecté suite à la désactivation accidentelle de l'antivirus.J'ai donc procédé à une désinfection: ccleaner, tune up utilities, scan avec spyware doctor et ad-aware, puis scan avec avast et enfin pour plus de sécurité un scan antivirus en ligne.J'ai ensuite lancé une recherche d'erreurs sur le disque c dans le poste de travail et enfin j'ai fait un rapport hijackthis que voici:Logfile of HijackThis v1.99.1
