Bonjour,

ça ressemble a un soucis d’accès aux serveurs avast durant l’installation du programme en mode “Online”.
Sauf à être avec un vieil OS XP ou Vista (ça ne semble pas être ton cas vu les répertoires utilisés) , je te conseille d’installer la version “Offline” de l’antivirus:
files.avast.com/iavs9x/avast_free_antivirus_setup_offline.exe
nb:on en a pas encore parlé sur le forum français , mais depuis la version 17.4 les utilisateurs XP et Vista doivent impérativement passer par la version “Online”

Merci pour la réponse, je vais essayer, et effectivement, non je ne suis pas sous XP ou vista… depuis au moins 10 ans! Non , là c’est windows 10
