Processeur surchargé : virus ou malware ???

Bonjour à tous,

Hé bien voilà, depuis une petite semaine, mon PC ne cesse de se ralentir (jusqu'à se bloquer) de façon inopinée, le processeur se mettant à tourner à 100%.

Spybot n'a rien déctecté, mon antivirus étendu McAfee non plus...

Si l'un d'entre vous pouvait décrypter le rapport HijackThis ci-joint, cela me serait d'une grande aide... Merci d'avance.
