[homepage pirate] probleme avec sexplorer.it

bonjour a tous
bon je ne serais pas tres originale en disant que j'ai un probleme et encore moins en vous disant lequel : le fameux sexplorer.it qui s'affiche dès que je me connecte a internet.
ajouter a cela une page d'accueil qui s'affiche a chaque fois que j'ouvre internet explorer (et qui n'a pas de nom, l'adresse est neuf.fr ma homepage mais c est une page de recherche qui s affiche)
apres avoir parcouru les forum a la recherche de solutions pour resoudre ça tout seul, je m'avoue vaincu et m'adresse donc à votre sagesse et vous adresse mon log hijackthis :
