Bonsoir,
j'ai regardé un peu quelques sujets du forum qui sont semblables au mien et j'ai téléchargé spybot, cleanup40 et a2 mais je en les ai pas lancé pour le moment.
Le problème c'est que je ne sais pas quoi retirer de hijackthis.
Après le rapport hijackthis j'ai oublié de te dire mais j'ai lancé adaware en mode sans échec et il m'a trouvé des cookies que j'ai supprimés.
Je te renvoie le nouveau rapport hijackthis (désolée ça m'était complètement sorti de la tête)
