CiD - Fenêtre intempestives =s

Bonjour,
Sur l'ordinateur de ma sœur, j'ai des fenêtres intempestives qui apparaisse et elles s'appellent "CiD: unepub"
C'était en fait ma soeur qui as installé le sponsor de MSN plus! Elle a enlevée après, mais les fenêtres continuent quand même à arriver.
J'ai fait un log Hijackthis et le voilà:
