bonjours!
voila jai viré norton antivirus de mon pc et jai installé avast!4 sur mon pc et lors de son lancement il me dit que "c:\windows\system32\userinit.exe" est infecté par le virus "Win32:Trojan-gen".
avast ne peux pas reparer et je ne pense pas pouvoir effacer ce fichier car dapres la base de donnée de microsoft c'est un des fichier clé du OS...
qq peux il me dire que faire svp?
