Fenêtre intempestive

Bonjour,

Même si je ne suis pas sur Internet, j'ai une fenêtre de pub qui s'ouvre tout le temps (be2 public site de rencontre !). J'ai beau nettoyer avec Ccleaner, Spybot et kaspersky, rien d'anormal est signalé.
Ci-dessous mon rapport Hijacktis. Il n'est pas parfait, à partir du moment je ne peux pas aller sur le mode sans échec. Chaque fois que j'y suis, au moment d'aller sur mon icône utilisateur, le PC s'éteint et redémarre tout seul.
J'espère que malgré tout, quelqu'un pourra m'aider.
Merci d'avance
