Probleme avec hclean32.exe

Bonjour tout le monde,
Je rencontre un problème actuellement, j'ai des messages qui n'arretent pas de sortir me signalant que ma machine est en danger, je sais que c a cause d'un troyen, je crois que c'est hclean32.exe (puisque norton le met en quaranatine a chaque fois), j'ai fais un scan avec hijackthis, je vous remercie pour toute aide :
