System error! your computer was infected by u

Bonjour,

J'ai besoin d'aide quant à l'apparition d'un message d'alerte lorsque je me connecte à internet via IE7 ou que je navigue dans mes dossiers et sous-dossiers dans le poste de travail.

Il semble que je sois infecté par un trojan.

J'ai effectué une analyse avec HIJACKTHIS dont voici le rapport :

Petites précisions :

cette fenêtre intempestive est un message d'alerte qui surgit comme du spam, avec un bruit d'alerte.
Voici le message :"SYSTEM ERROR! Your computer was infected by unknown trojan. It's dangerous for your system (critical files can be lost)!"

Puis il m'est demandé de télécharger l'antispyware pour nettoyer...

Dans l'attente de lire quiconque qui se sent l'âme d'un sauveur!...

Merci d'avance
