ciao a tutti il pc sono 2 giorni che fa il pazzo. tutto è cominciato con dei programmi scaricati che eranoo probabilmente deii virus, poi il pc andava in crash (schermata blu con scritte varie), poi oggi all'avvio mi dava solo una finestra "è stata apportata una modifica non autorizzata a windows" e quindi mi potevo solo collegare a internet. Non riuscendo a risolvere ho avviato il pc con F8 "ultima impostazione funzionante". Avast continua ha trovare (ma non ha debellare ". physicaldrive0 mbr tdl4").

grazie in anticipo!
