PC infecté mais par quoi?

Bonjour,

Je viens demander de l'aide ici car je ne sais plus quoi faire pour résoudre mon problème. Mon PC est infecté mais je ne sais pas par quoi. Le symptôme le plus probant est la curseur de la souris qui se déplace tout seul, curseur qui résiste lorsque j'utilise ma souris (trojan, spyware?).

Après avoir fait un scan avec Avira Antivir, Ad-awre, Spybot et Malware byte: Absolument rien!!!! Étrange... Quelqu'un à une idée?
Je vous met ci-dessous un log de Hikackthis.

Merci d'avance de votre aide
