Virus - Trojan Dropper récalcitrant. Help!!!

Bonjour,

Voilà je sollicite votre aide car j'ai un trojan qui a infecté mon pc hier alors que j'installais un logiciel. Il s'agit du virus "Trojan-Dropper.Win32.Peace.cw ". Mon antivirus F-Secure Firewall n'en est pas venu à bout. J'ai presque tout essayé mais je n'arrive pas à l'éradiquer.

Depuis mon ordi ne cesse de planter, il rame en permanence, firefox bloque toutes les 2 secondes, des dossiers ont été modifiés ou supprimés, et pire, ma livebox m'indique que j'utilise Internet même quand ma machine est en veille!!!

Si vous pouviez juste m'aider à lire mon rapport HiJackThis, je vous en serais très reconnaissant! (j'avoue que ça me bouffe mon week-end :S). Merci beaucoup! ;-)
