Je ne sais quel virus...

Bonjour a vous.

Depuis plus de deux jour, mon ordi agit de façon disons... pas normal. À chaque fois que je suis sur le Poste de Travail, la page prend 30 a 60 secondes a arriver, mon ordi reconnait plus toute mes cd, il a déjà rebooté 1 fois et quand je tappe une URL sous explorer, ça prend plus d'une minute pour que la page apparaisse mais ça ne me le fais pas avec FireFox. J'ai essayé Norton antivirus, Doctor Spyware, Spybot, Panda, Spy sweeper, AVG Free, Symantec ActiveScan, le logiciel de F-Secure et la détection de virus windows.

Je poste mon log HijackThis
