Ciao,
stamattina ho formattato il portatile.
Da quando ho reinstallato l'adsl, non riesco ad accedere ad alcuni siti

Ad esempio apro il sito messenger ( http://www.messenger.it/ ) ma se clicco su scarica messenger mi da "indirizzo non trovato"

Ho provato a scaricare clamwin ma ho dovuto cambiare mirror per eseguire il download; non riesco pero ad aggiornare le firme dei virus ("WARNING: Can't get information about database.clamav.net: No IP address")
