Iexplorer 100% de l'uc

Bonjour

Voilà, j'ai un souci : l'UC est bloqué à 100% du à IEXPLORER.EXE qui utilise la majorité des ressources.
J'ai effectué un scan antivirus mais rien de détecté (Avast + Scan online Symantec).
Y aurait-il quelqu'un qui pourrait me rendre le service d'interpréter le log Hijackthis ?
Merci d'avance j'espere que vous pourrais m'aider sa fait 1 mois que sa dure...
