Ordi tres lent, virus ou disque dur?

Bonjour,

g un gros soucis avec mon ordi. il met très longtemps à s'allumer, alors que je faisais un scan avec avast j'ai eu l'écran bleu puis l'ordi c éteind. avast avait trouvé un trojan mais malgré la mise en quarentaine il n'y a pas eu d'amélioration. j'ai alors utilisé Hijackthis, un site repère les logiciel suspects, j'ai suivi les conseils mais je n'ai toujours pas d'amélioration.
avant c problèmes une fois l'ordi c arrêté au démarage par faute de batterie, il alors affiché un défaut sur le disque dur : transfert de données + pertes.
voila mes mésaventures, mes questions sont : ai-je encore un virus, le souci vient-il du disque dur?
je vous fais passer le scan de hijackthis
