[Spyware] links4all.biz

Bonjour, en fait voila, ma soeur a maladroitement accepter un fichier sur msn, et depuis, a chaque demarrage j'ai une page internet avec l'adresse suivante qui s'ouvre links4all.biz
Ce n'est rien de grave mais juste un spyware assez embetant je pense... J'ai deja chercher des solutions sur internet mais je prefere qu'on s'interesse juste a mon cas :s... Voila mon rapport Hijackthis :
