Bonjour,
Et bien moi aussi, ce satané "www.wwwamnc1.com/fallback.php", m'infeste mon ordi et j'ai beaucoup de mal à ouvrir ma messagerie.
Auriez-vous la gentillesse de m'aider afin que je puisse me débarrasser de ce "poison".
merci d'avance.
Réginette

Configuration: Windows XP
Internet Explorer 7.0

J'ai donc suivi les conseils suivants :
- Télécharge HiJackThis.zip de Merijn sur ton bureau.
- Dézippe le dans un dossier prévu à cet effet.
** exemple C:\hijackthis < Enregistre le bien dans c : !

- Double-clique dessus
- Génère un rapport en suivant ces indications :
- Exécute le et clique sur "Do a scan and save log file".
- Le rapport s'ouvre sur le Bloc-Note.
- Colle le rapport ici, pour cela :
- Menu Edition / Selectionner Tout
- Menu Edition / copier
- Ici dans un nouveau message : clic droit / coller

et voici donc le rapport généré :
