Cheval de troie trojan

Bonjour tout le monde,

malheureux réflexe oblige, un copain sur msn m'envoie un lien, je clique dessus, et me voila infestée
le virus. ce cheval de troie qui envoie ce même liens à tous mes contacts msn toutes les 5mn s'appelle trojan-downloader.win32.purityscan.fk

évidemment, kaspersky met la main dessus mais n'arrive ni a l'éradiquer ni a le mettre en quarantaine

voilà ce que donne le rapport de hijackthis:
