Ciao, ho un Asus k501, ormai da 20 giorni con navigazione quasi impossibile (3-5 k...), mentre tutte le operazioni che non utilizzano internet vanno veloci come sempre. Ho provato con: IE, Firefox e Chrome.
Window 7 professional aggiornato e 4 giga di RAM, tutto sembra ok.
Ho fatto scnsioni antivirus e altro am non ho trovato niente. Potete controllarmi il log?
Grazie!!!

Vedo che sei nuovo, un saluto e benvenuto nel forum.
Hai troppe toolbar installate e questo potrebbe essere il motivo di una navigazione lenta.
Fixa ed elimina queste voci:

Poi installa QUESTO programma, lo aggiorni e fai una
scansione COMPLETA non veloce, elimina quello che trova.
Poi fai una pulizia con Ccleaner compreso il registro, fai anche una deframmentazione.
Vediamo se la navigazione migliora. Ciao

Contento che tu abbia risolto. Ciao
