Pc infecté

j'ai cliqué sur un lien sur MSN il y a deux jours et depuis j'ai un virus comme beaucoup l'ont eu apparemment. C'est un cheval de troie qui revient sans cesse malgré avast qui le détecte. (smal JMH ) un nom de ce genre là... A chaque fois que je rallume mon pc il revient et mon MSN beugue... Merci d'avance

ok je le fais tout de suite et vous tiens au courant

voilà le rapport de mon scan antivir
