Ciao, mi chiamo Erika.
All'avvio di windows avast mi trova il virus vbs:malware-gen. Mi raccomanda di metterlo nel cestino. Cosa che puntualmente faccio ma puntualmente al successivo riavvio mi riappare l'avviso. In più mi appare sempre una schermata blu in cui mi si dice di mettere un antivirus o uno spyware nel pc. Essendo alquanto impedita in fatti informatici, non so proprio dove mettere mano.
