[Virus] Souris se "téléporte" et clic...

Bonjour.
Depuis quelques jours ma souris se met à ce téléporter d'un bout à l'autre de mon écran...
Elle peut même cliquer sans que je la touche.
J'ai essayer de changer la souris/le tapis/débrancher/rebrancher/reboot l'ordinateur... rien,toujours le même soucis.
J'ai même formater mon ordinateur ! En m'assurant d'avoir bien effacer les fichiers "old".
Même quand je ne suis pas connecter à internet ma souris bouge.


J'ai fais un scan de Avast minutieux il n'as rien détecter,j'ai essayer CCleaner,Spybot toujours le même soucis.

J'attends votre aide,merci bien.


EDIT:J'oubliais !
Firefox m'ouvres des pages internet,au hasard ...


EDIT:Rapport HiJack.
