Spyware concernant le démarrage d' IE

Bonjour,

je suis plutôt débutant, mais en parcourant votre forum, je devrai être capable de décrire mon pb:

Je suis probablement infesté par spyware qui a le malin plaisir de forcer la page de démarrage d'IE vers un site qui me propose des tas de services d'achats, et en particulier des spywares..!!.

Je vous envoie mon hijackthis, en espérant que vous me proposerez une marche à suivre.

merci d'avance;

Ci-joint mon fichier log.
