Pour préciser un peu, il s'agit d'un ordinateur que j'ai récupéré a mon grand père (déjà ça part mal...) qui avait été formaté et sur lequel était installé kaspersky mais il fallait entrer un numéro de licence.
Du coup j'ai voulu installer un antivirus gratuit mais je me demande si l'installation ne s'est pas lancée avant que j'ai fini de désinstaller kaspersky.
Il s'agit d'un portable acer Extensa 5220 qui tourne sou windows vista.

Quelqu'un aurait-il une solution car maintenant l'ordinateur se retrouve sans antivirus avec l'impossibilité d'installer avast.
Merci d'avance
