Bonjour,
Je suis désespéré ! Comme un idiot, j'ai cherché sur LimeWire, dès que j'ai ouvert un fichier, l'infection s'est produit.
J'ai réussi à effacer la plupart des malwares (SpyBot, Ccleaner, etc) mais il y a toujours des redirections quand je recherche sur Google !
De plus, des sites comme SpyBot, Avast! sont bloqué. J'ai essayé plusieurs solutions sur le web, rien n'a arrangé mon problème, je commence à désespérer.

Au cas, voici un HijackThis de mon ordinateur :
