Salut,
Essaie de passer t scan en mode sans echec:

COMMENT UTILISER DE LE MODE SANS ECHEC-A IMPRIMER:

-redemarre ton pc
-dès que le chargement du bios"c' est dire toute les ecritures blanches dans le fond noir" appuis simultanement sur la touche F8.
-a l' aide des fleches selectionne "mode sans echec"
-Ensuite passe t scan en enregistrant les log pour pouvoir les envoyé sur se forum.

Salut,

pour suivre merci

bonsoir à tous,

je vais déjà essayer de lancer les programmes en mmode sans echec puis je ferais un scan bitdefender cette nuit. je vous posterais le rapport demain matin je pense.

antivir marche maintenant, c'était juste un problème de configuration avec mon pare-feu online armor, maintenant ça marche et j'ai fais un scan.
antivir m'a détecté un "warning", je ne sais pas si c'est un virus ou si c'est juste un truc qu'il n'arrive pas à lire mais voici le rapport :
