Page d'accueil redirigé vers des images

Bonsoir tout le monde,

Je vous écris au sujet d'un problème très agaçant à la longue : chaque fois que je clique sur l'icone pour la page d'accueil (http://google.fr) on me redirige vers des images aléatoires : aladin, homme à poil...or, l'adresse est bien http://www.google.fr, de même dans les paramètres.
De plus, je dois réactualiser environ 50 fois pour qu'une page se charge, ou alors, quand je clique sur un lien quelconque, on me dit que le site n'existe pas, et en fait, en réactualisant plusieurs fois, le site existe bel et bien. Je vous poste mon log Hijack This :
