Ciao,mia figlia ha un mini pc con Win7,si è sempre connesso bene sia con Netgear sia con la chiavetta 3,da una settimana a questa parte non si connette e se lo fa regge pochissimo.
Io non conosco questo SO,mi potete consigliare qualche programma per controllare se c'è qualcosa che non va ?

Windows7 è un SO che funziona benissimo. Ho letto in giro che la chiavetta della 3 da qualche tempo è un pò capricciosa.
Altri che usano lo stesso prodotto potranno dirti ancora di più al riguardo.

Sarebbe d'aiuto anche a noi sapere cosa ha fatto Hijackthis !!

Eccomi,questo è il log di ieri :
