Bonjour,

Depuis quelques jours j'ai remarqué que mon PC était très lent. J'ai donc regardé dans le gestionnaire des tâches/processus et j'ai remarqué que plusieurs programmes (iexplorer, msnmsgr, utorrent...) étaient lancé plusieurs fois.

Voici mon log de Hijackhis, quelqu'un aurait-il l'amabilité de l'interpréter et de m'aider a réparer ce problèle assez gênant?
