Problème à l'arrêt de Vista

Bonjour,

Pour mieux comprendre : http://www.commentcamarche.net/forum/affich 11904038 arret et demarrage vista plutot lent?#13

Voilà, mon ordinateur (de temps en temps) met du temps à s'éteindre (je ne suis pas du genre à faire "arrêter" deux secondes après avoir fermer une applications)

Et donc voici mon log hijackthis, car, la personne qui m'a aidé m'a dit qu'il serait possible que je sois infecté :
