Spywares/Malwares dans mon ordinateur

Bonjour, mon ordi est infecté par des malwares dont Adssite ( fenêtres apparaissent et indiquent « Ads served by Adssite » et Rightonadz (fenêtres apparaissent et indiquent « Ads served by rightonadz).Mes recherches sur google sont toujours redirigées vers des sites bidons. Étant donné que le freeware Ad-Aware, c'est de la grosse marde en vrac (repère 40 dossiers infectés, les supprime mais ils finissent toujours par revenir, alors à quoi sert AD-Aware?) et bien j'aurais besoin de votre aide. Voici le log de Hijackthis:
