Infecté par win32 trojan gen

bonjour a toutes et a tous.

je suis infecté par win32 trojan gen. parmi les symptomes : impossible de remplir des formulaires en ligne ( login et password de boite mail, par exemple , ou de poster sur ce forum : je suis sur une autre machine, la ) et surtout impossible de booter en mode sans echec ( ca sent le roussi, non ? ).

apres avoir largement depassé le stade de la panique, j'envisage sereinement le formatage complet, mais si quelqu'un avait mieux a me proposer, je suis preneur.

merci d'avance.
