Buon giorno a tutti, da tre o quattro giorni, tute le volte che clicco sulla pagina principale si apre la finestra "impossibile visualizzare la paagina web". Ricliccando si apre normalmente. Potreste dirmi se per caso c'è qulache "intruso"??? Anche se dopo varie scansioni a me non risulta nulla. Grazie buona giornata
