Grazie Alfonso per il tuo aiuto !
Nonostante le tue istruzioni non sono riuscito a risolvere i miei problemi con Internet.
Innanzitutto non so come eliminare le righe tipo :
C:\WINDOWS\System32\wvsvc.exe
-
C:\WINDOWS\System32\ptmedsrv.exe
dal momento che non appaiono nella schermata di hijackthis con le caselle di spunta.
Il problema che riscontro nel mio portatile riguarda fondamentalmente la connessione ad internet. Infatti, non appena avvio la connessione , questa incomincia a mandare una serie infinita di byte in uscita ( senza alcun apparente motivo ) riducendo così quasi totalmente la possibilità di aprire anche banalissime pagine web.
Ti rimando quindi il file log che ho nuovamente effettuato.
