Problème avec shdoclc.dll/dnserror

Bonjour à tous
depuis quelques temps j'ai un pb avec mon ordi portable (Win xp)
lorsque je démarre mon ordi, la page de démarrage Internet s'affiche avec une erreur du type shdoclc.dll/dnserror. Je sais vraiment pas quoi faire, en plus je n'y connais pas grand chose en informatique!! j'ai besoin de vous!
Je joins le log Hijackthis de cette machine ci-dessous :
