ho capito tutto.
adesso ho un piccolo dubbio.
come mai il mio computer, pur avendo una linea adsl era infettato con dei dialer?
forse perchè in precedenza ho adoperato un 56K?
Se io apro un sito e mi appaiono delle ragazze nude, significa che ho qualche virus o dialer oppure può succedere senza che io abbia infezioni nel cpu?
