Erreur de chargement au lancement de Vista

bonsoir à tous, j'ai un problème au lancement de Vista, 2 messages d'erreur de chargement s'affiche pour les fichiers: afpiaoop.dll et yayuvUMCt.dll. Je suppose que cela vient d'un problème d'infection mais je suis incapable de trouver une solution (mes connaissances dans ce domaine sont assez pauvres).

Merci d'avance pour votre aide précieuse.

J'ai deux croix rouges sur le site de vérification d'hijackthis, les voici, je pense que ca pourrait aider:

O4 - HKCU\..\Run: [MSServer] rundll32.exe C:\Users\Julien\AppData\Local\Temp\yayvUMCt.dll,#1
Nasty (2.62 / 5.00)
O4 - HKCU\..\Run: [LSA Shellu] C:\Users\Julien\lsass.exe

et deux avec points d'interrogation:

O4 - HKCU\..\Run: [080d5ca6] rundll32.exe "C:\Users\Julien\AppData\Local\Temp\wihsqcgj.dll",b
Neutral (3.06 / 5.00)
O4 - HKCU\..\Run: [BM0b3e6f3a] Rundll32.exe "C:\Users\Julien\AppData\Local\Temp\afpiaoop.dll",s

Bonjour

Télécharger sur le bureau

OTMoveIt2.exe

---------------
relancer hijack
"Do A System Scan Only"

cocher ces lignes et clic ensuite sur FIX CHECKED


O4 - HKCU\..\Run: [MSServer] rundll32.exe C:\Users\Julien\AppData\Local\Temp\yayvUMCt.dll,#1
O4 - HKCU\..\Run: [LSA Shellu] C:\Users\Julien\lsass.exe
O4 - HKCU\..\Run: [080d5ca6] rundll32.exe "C:\Users\Julien\AppData\Local\Temp\wihsqcgj.dll",b
O4 - HKCU\..\Run: [BM0b3e6f3a] Rundll32.exe "C:\Users\Julien\AppData\Local\Temp\afpiaoop.dll",s

Ensuite vides ton dossier TEMP dans C:\Users\Julien\AppData\Local\Temp ( Vides le mais ne le supprimes pas )

Puis suprimes C:\Users\Julien\lsass.exe
