Bonjour
Depuis environ 1 semaine, sans raison apparente (toujours lorsque Outlook XP est ouvert), zone alarm me demande d'autoriser une application nommée "DW.EXE", a priori rien de bien méchant.
Mais très rapidement après mon navigateur ne fonctionne plus ou me lance des pages érronées (que je lui accorde l'accès ou pas. Après un reboot, tout revient en ordre (jusqu'à la fois suivante).
PLEASE HELP

Je ne vois rien de bien méchant.
J'ai passé "Hitmanpro II", CleanUp 4.0!, adaware, spybot... C'est un véritable casse-tête
