Hijackthis - pc chauffe : virus?

Bonjour,
J'ai récemment remarqué que mon pc chauffe plus que auparavant. Il chauffe tellement qu'il se met en veille au bout d'un moment.
J'avais déjà connu ce genre de problèmes mais c'est de plus en plus fréquent maintenant. J'ai remarqué que lorsque j'utilise la batterie (pas branché à l'alimentation), le pc fait moins de bruit. Je me demande si il ne s'agit pas d'un virus.


Mon PC est un HP pavillon DV6 acheté en Septembre 2009. (il a donc un an - donc encore neuf non?).

J'ai trouvé plusieurs personnes ayant un problème similaire mais les solutions données ne sont pas toujours applicables.

J'ai entendu parler de Hijackthis qui permet de voir si sa machine comporte des bugs mais je suis totalement incapable de corriger les problèmes si il y en a (parce que je ne sais pas interpréter les résultats).

Je poste le résultat de Hijackthis si quelqu'un peut m'aider.
MERCI
