Un virus m'empeche d'installer un antivirus..

Lut'

1) HJT n'est plus très fiable
2) symptome de Bagle...

Bagle est une infection qu'on attrape en téléchargeant des cracks sur peer to peer.
Il supprime les antivirus, firewall, empèche le redémarrage en mode sans échec... et ralentit considérablement l'ordinateur.

Est ce que tu as ce message "....win32 application non valide" quand tu essaye d'executer un programme, ou d'installer un AV ?

bonjour,
tu peux aller sur secuser.com et aller dans antivirus en ligne et lancer un scan.
s'il trouve le virus il le supprime directement ce qui te permet de télécharger un antivirus gratuit ( avira-antivir est pas mal dans sa version gratuite) après et de le mettre à jour.
si secuser ne trouve rien ,fais un scan ici : http://www.kaspersky.com/kos/eng/partner/71365/pages/default/check.html?n=1253684570253
kaspersky online scanner 7.
je pense que tu devrais te débarrasser vite de ce virus.
ensuite tu peux télécharger et installer cet antivirus gratuit très bon.
