la voce sopra la puoi sicuramente eliminare, nella scansione non mi sembra di vedere problemi pero' ASPETTA qualche amico esperto che sicuramente ti dara' consigli sicuri.

A dire la verità sembra funzionare tutto, tranne l'audio.
Al posto di avast ho installato Avira, il quale mi ha ripulito il pc da ben 7 virus che avast non vedeva.
In ordine ho usato: Beagled.exe, Elibagla.exe, Malwarebytes e Combofix disattivando il ripristino della configurazione di sistema e tassativamente offline.
Ho fatto bene?
Grazie
