Probleme UC = rame

L'UC, c'est l'utilisation du processeur, s'il est à 100%, c'est qu'il travaille à fond, et donc ton ordinateur ira beaucoup moins vite pour d'autres applications. Pour Firefox, je ne pense pas que ce soit normal, tu as la dernière version, ça ne doit pas venir de là, le problème vient sans doute de vista.

RE : Merci de ta réponse ça a été très vite ^^!

Et oui j'ai la dernière version de firefox mais je ne sais pas d'où viens le problème si il ne vient pas de la .
Merci de bien vouloir m'aider .

RE Peut être que tu aura besoin de mon rapport hijack alors je t'en fais part :
