Bonjour,

je suis débutante en informatique. j ai reçu un message suite à une analyse de mon antivirus, disant que ma base était corrompue. je ne sais pas ce que cela eut dire. j ai tenté de télécharger des logiciels un peu au hasard mais on j ai peur d' avoir fait une bêtise en téléchargeant un virus.
