Bon alors depuis un certain temps mon pc rame beaucoup, mon processeur devien fou (passe de 2-20% a 90-100% de facon aléatoire). de plus, je n'ai plu d'onglet dans mon gestionnaire de tache, et ayant cliquer par erreur sur afficher le service et bien impossible de revenir a la liste de processus puisque je n'ai plus les onglets :S

Toujours pas de réponse... Je sais pas si c'est permis mais je fait un petit UP car mon problème est rendu loin dans le forum, je n'ai donc pas grand chance de recevoir de l'aide...

Aussi, si j'ai un autre problème, est-ce que je crée un nouveau topic séparé pour l'autre problème, ou je l'ajoute ici pendant qu'on est sur mon cas?

Bonjour,

Apparemment ok.

Désinstalle correctement Avast! pour le remplacer par AntiVir.
Pourquoi changer ? Avast! vs AntiVir

Fais un scan complet puis poste le rapport en fin d'analyse.
AIDE : Tutorial sur l'antivirus AntiVir Personal Edition Classic

En fait j'avait Antivir, mais j'ai changer pour avast pour voir si celui-ci trouverait quelque chose... aucun des 2 antivirus n'a rien détecter. je précise, j'avait déja tout ces problèmes AVANT de changer antivir pour avast. Est-il tout de meme necessaire de changer encore pour faire un scan étant donné qu'il n'avait rien trouver?

Fais quand même un scan rapide

Info supplémentaire, peut-être lié au problème: j'ai assez souvent des "bip" machine (son de bip machine mais ils proviennent des haut-parleur, pas de l'ordinateur), irrégulier, il en a quelque un, des fois pendant 1 min, et puis ça disparait. Keylogger ? De plus, quand je lance Windows Live Messenger, j'ai un message d'erreur valeur nul quelque chose, voulez vous continuer a exécuter le script sur cette page? et tant que je n'ai pas fait oui ou non la touche "enter" ne fonctionne pas dans messenger. Seulment dans messenger.

Peut-être aucun lien mais je crois utile de fournir tout les détails, au cas-où.

image :

Le bip c'est matériel et ton erreur n'est pas lié à une infection

Que dois-je faire alors? Je ne crois pas avoir de problème matériel, j'ai tout le matériel par défaut, c'est un portable :s

Pour les bips > section Hardware
Pour le script > Logiciels

et pour mon gestionnaire de tache corrompu et UC instable, hardware aussi?

Pour l'UC instable c'est possible.

Est-ce que tu pourrait transférer mon topic dans la section Hardware s'il-te-plait?
