Multiple Virus! (HJT inclus)

Bonjour,

J'ai plusieurs Virus qui me cause plusieurs problèmes: Internet explorer ne fonctionne plus, le système est très lent et plusieurs autres problèmes, l'ordinateur est complètement paralysé.

J'utilise McAfee qui a détecté plusieurs virus, mais le dernier est W32/autorun.worm.bl.Je suis actuellement en train de faire une recherche avec spybot - Search & Destroy et j'ai fait une autre avec CCleaner avant.

Merci énormément pour votre aide !

Voici mon rapport HJT:
