[Explorer.exe] 99 du processeur UC à 100%

Bonjour,
Voila ca fait plusieurs semaines maintenant que mon ordi rame a mort l'exporer utilise 99 du processeur et mon uc est a 100%.
J'avais lancé scan avec norton, bitdefender, hijackthis, spybot
J'avais trouvé plein de trojan (dialer.trojan,trojan.Zlob,Trojan.downloader,trojan.agent,trojan.klone, Trojan.java,behavesLike:win32.ExplorerHijack, Trojan.PornDialer...AdwareHotbar)
Maintenant ca fait 2 semaines les scans revelent plus rien et pourtant ca rame toujours.
J'ai meme essayé de résoudre mon pb en enlevant InProcServer32 de la base de registre mais ca na rien fait.
Je sais plus quoi essayer besoin d'aide svp !!

Voici le rapport de Hijack this si ca peux vous aider :
