Proceseur a 100%

salut tout le monde
hé bien oui je reviens ici avec un petit problème pour vous:
mon pc sous vista(médion core2duo 1.8 ghz 3go ram 9600GT) a le proc a 100% depuis hier
et pourtant dans la liste des processus aucun ne bouffe plus de 1% ou alors une quantité de ram dérisoire
je pense peut etre a un virus
voici mon rapport hijackthis:

Bonjour.

Même si c’est un virus il y’ a forcément un (des) processus en cause ,

Télécharger Process Explorer :

technet.microsoft.com…

waow super merci
je ne connaissais pas ce soft
en fait cette soudaine utilisation du processeur correspondait a l’installation de folding@home que j’avais sans doute paramétré pour utiliser tout le processeur disponible
merci pour l’info :slight_smile:
