Ciao e grazie

Dunque infezioni non se ne vedono, però hai troppe voci in avvio che non vanno bene e non servono possono creare solo impicci, quindi disattivale e lascia solo Avast, puoi farlo anche con Ccleaner, vai in Strumenti>Avvio e fai doppio clic si ogni voce e così si disattiva, vedrai apparire NO alla sinistra invece di SI, i programmi non vengono toccati si disattiva solo l'avvio automatico.
Per il problema del file host leggi qui: https://support.microsoft.com/it-it/kb/972034
Ma potrebbe dipendere anche da win 10 che io non uso.
Vedo che hai 2 indirizzi ip, uno di google e un altro della H3G, io ti consiglio di lasciare solo quello di Google e eliminare l'altro, per toglierlo basta fixare la seguente riga dal log HJT:
O17 - HKLM\System\CCS\Services\Tcpip\..\{A0DD4083-2FB3-4562-828A-B6105EC770BD}: NameServer = 62.13.173.94 62.13.173.95

Fai una pulizia del Registro. Ciao

Ciao e grazie per l'aiuto che mi state dando, volevo dirvi che per quanto riguarda HJT spunto la casella riguardante la riga O17 - HKLM\System\CCS\Services\Tcpip\..\{A0DD4083-2FB3-4562-828A-B6105EC770BD}: NameServer = 62.13.173.94 62.13.173.95 poi clicco su Fix checked sparisce tutto quello che era apparso Quando avevo premuto Scan ma quando lo ripremo quella riga riappare. Cosa sbaglio? Ciao

Se hai disattivato anche le voci in avvio sei a posto.
Ciao
