Rootkik + look2me

voila:
j'utilise avast qui me détecte un fichier infecté "rdriv.sys" dans windows, system32
fichier inexistant en mode sans échec et insupprimable en mode normal car "utiliser par un autre programmme..."
ewido le repère comme fichier infecté trojan rootkik.k mais je n'arrive pas à le supprimer
de plus ewido me trouve pleins de fichiers infectés par look2me que je lui demande de supprimer en mode sans échec mais ils sont toujours là à chaque scan....
je post au cas où un post avec hijackthis
merci par avance à ceux qui me répondront
