Virus W32 Myzor FH@yf

Bonjour,
Je suis infecté par le Virus W32 Myzor FH@yf, pourriez vous m'aider.
En deux mots une nouvelle barre Security Toolbar 7.1 vient d'arriver avec celle de google, et il m'est proposé de télécharger des antvirus (trop chère pour un étudiant) alors que j'ai déjà antivir. De plus il m'est informé de la présence de W32 Myzor FH@yf, et windows m'indique qu'un compasant ne fonctionne plus (IPC ou quelque chose comme ça). J'ai suivi les procédures indiquées dans d'autre chat de ce site, mais rien a faire je rencontre encore le même problème. Voici les log de AntiVir et de de HijackThis :
