PC infecté

Bonjour,

J'ai un PC qui tourne avec Avast antivirus et Windows Defender comme antispyware et sont à jour.
J'ai fait une analyse intelli-san avec spyware doctor qui me trouve un certain nombre d'entrées hosts infectées (trojan fake alert,adwares..)
Lorsque je veux supprimer ces infections spyware doctor me dit que toutes les infections n'ont pas été effacées et elles restent toujours présentes.

A quoi sert Window Defender s'il laisse passer tous ces spywares ?
Pourriez-vous m'aider pur éradiquer toutes ces menaces ?Merci.

Je joins le rapport hijackthis de Trend Micro:
