Trojan.cachecache.warm

Salut à tous,

je travaille sur le windows XP et NortonAntivirus a detecté un virus Trojan.cahecache dans c:\windows\system32\rdriv mais il n'arrive pas à le desinfecter ni à le supprimer. j'ai executé "Hijackthis" mais il recommande d'etre prudent sur les actions à entreprendre et je voudrais avoir l'avis d'un expert voici ce que j'ai eu dans le logfile:
