RUN DLL wkdhed8s7.dll ???????

Salut,
quand je boot mon pc, juste avant l'ouverture de mon bureau j'ai un fenetre qui s'ouvre avec ce message:

" Run DLL

Erreur de chargement de c:\windows\ystem 32\wkdhed8s7.dll

Accès reffusé "

Quelqu'un pourrait m'aider à ce que mon ordi démarre normalement.
Si ça peut etre utile voilà le Highjack:
