Supprimer lo.st et eorezo

Bonjour,

depuis quelques temps, la page d'accueil lo.st apparaît sur mon ordi de même que de nombreuses publicités ; par moment, les pages de pub s'ouvrent infiniment m'obligeant à redémarrer l'ordinateur...
j'ai téléchargé AD-Remover, scanné et voici le rapport qui apparaît
