Virus sur pc.. se bloque au demarrage

Bonjour à tous.

voilà mon problème, j'ai effectué une analyse de mon pc avec spybot et malwarebytes. Mon pc étaient infectés de plusieurs fichiers dangereux et ils ont été supprimés par les logiciels sauf que depuis mon pc ne s'allume plus correctement. J'ai un Medion Intel pentium 4CPU 3.06 GHz 960Mo de RAM. Quand j'appuie sur le bouton de l'allumage , j'entend mon ordi tournait puis se bloque sur l'écran noir là je dois l'éteindre par la prise courant, le relancer. Celà peut marcher du premier coup comme le faire 4 à 5 fois avant que l'ordi se lance vraiment.
On m'a conseillé de faire une analyse avec hijackthis et de poster le log ici pour trouver de l'aide et résoudre mon problème.

voilà le log :
