Double problème : rdriv.sys et msdirectx.sys

Bonjour,

Comme le titre l'indique, je cherche à me débarasser des virus qui "génèrent" ces fichiers troyens. J'ai bien cherché à comprendre comment vous déterminiez quelles lignes dans HiJackThis et quels programmes effacer, mais là je déclare forfait (mais si vous pouviez m'expliquer, je serai ravi). Voici le log de HiJackThis :
