Ciao luciano, dal log non si vede molto, tieni presente che HJT con Seven non è molto affidabile, comunque facciamo un pò di pulizie ed eventualmente usiamo Combofix.

Chiudi tutti i programmi e disconnesso lanci HJT e clicca sul secondo pulsante: Do a system scan only poi metti la spunta alle voci che ti indico e alla fine clic su Fix checked.

Chiedi al tuo amico se ha messo lui questi indirizzi IP: 94.126.8.1,94.126.8.2, se non li conosce allora bisogna eliminare anche le 4 voci 017.

Vedo che c'è Malwarebytes, aggiornalo e fai una scansione COMPLETA non rapida, elimina quello che trova.

Poi avvia win in modalità provvisoria: Vai su Start/Esegui e digita MRT e dai ok, nella finestra successiva scegliere analisi completa, avvia, se chiede di eliminare dei file acconsenti, alla fine verrà rilasciato un file coi risultati.
