Attaque de pop up, drivecleaner 2006 : sos !

Bjr, je suis attaquée de toute part par des pop up de drivecleaner 2006 et autre pages qui se téléchargent tout le temps et bloquent le travail normal de l'ordi.
Je poste ici le rapport de highjackthis et si quelqu'un pouvait m'aider à l'analyser ça serait super !
D'avance merci !
