Vous avez corrompu votre fichier hosts en le bricolant ou un logiciel malveillant y a inscrit des redirections de noms de domaines vers des serveurs de cybercriminels ou empêchant d'atteindre les serveurs de logiciels et solutions de sécurité (antivirus monomoteurs, antivirus multimoteurs, pare-feu...). Bien que ce fichier hosts soit un simple fichier texte qui peut être manipulé avec le bloc-notes (notepad) de Windows, la solution la plus simple pour le restaurer dans sa version d'origine (sortie d'usine) est d'utiliser un petit logiciel gratuit (il en existe plusieurs qui font cela). Nous choisissons d'utiliser RogueKiller (un logiciel développé par Tigzy).
Télécharger RogueKiller (en version 32 bits ou 64 bits selon votre version de Windows

Si votre version de Windows est antérieure à Windows 7, il ne doit contenir qu'une seule ligne qui est :
127.0.0.1 localhost
(il s'agit de la « boucle locale » explicite)
Si votre version de Windows est Windows 7 ou postérieure, cet onglet doit être vide (la « boucle locale » est devenue implicite et ne peut plus être corrompue par une attaque de type « hijacking »).
S'il contient l'unique ligne suivante, cela n'a pas d'importance
127.0.0.1 localhost
Si c'est le cas, votre fichier hosts ne contient aucune valeur suspecte.
Sauf si vous savez exactement ce que vous faites avec votre fichier hosts, cliquez sur le bouton .
Quittez RogueKiller. Vous pouvez supprimer ce logiciel dont l'évolution est très rapide et qui, demain, ne sera déjà plus à jour.
Si les autres onglets de l'analyse par RogueKiller contiennent des valeurs (ne sont pas vides), nous vous recommandons d'en parler sur un forum d'entraide et de décontamination avant de tout supprimer.
