Ciao a tutti.
Ho da qualche giorno un problema molto fastidioso che non riesco a risolvere.
Mi sono beccato un virus e nonostante abbia fatto una pulizia completa, rimane il problema che molte pagine web non si aprono più. Non è un problema di linea perchè con un altro pc e lo stsso router riesco ad accedere a quei siti.
Potrei postare quì logfile di hijackthis così magari qualcuno mi ci da un'occhiata e mi consiglia quali processi killare?
Grazie
