J'ai tout essayé: le "Fix checked" de HijackThis ne marche que jusqu'au prochain reboot, idem pour les différents scans de Spybot Search & Destroy, Adaware et MalwareBytes anti-Malware passés en mode Safe de Windows. J'ai aussi essayé le SmitFraudFix mais cela ne marche pas non plus. Quelqu'un saurait comment s'en débarasser? Par avance merci
