[Virus] Infecté par trojan-backdoor-us15info

Bonjour,
mon ordinateur est infecté par un cheval de troye
il affiche sans arrêt :

http://www.e-christmascards.info/card232.
exe

Quand je dis sans arrêt, j'check :D http://www.e-christmascards.info/card232.execheck :D http://www.e-christmascards.info/card232.

bah, voilà, c vraiment sans arrêt...
bref, ne cliquez surtout pas sur ces liens, il m'ont pourri mon aprem

j'ai fait tourner a-squared free, clean up
j'ai téléchargé spy sweeper qui m'identifie : trojan-backdoor-us15info
mais qui ne le détruit pas, et qui me trouve des fichier BIT5, BIT6,BITBB.tmp, etc...

avast bloque ce même cheval de troye (enfin, je suppose que c le même) mais sans le supprimer...

je suis un novice et en dépit du tutorat, je n'ose pas "fixchecker" des lignes de hijack

voici ce que hijack me donne :
