Le voci 04 sono programmi in avvio automatico che non servono.
Alla fine fai una pulizia con Ccleaner compreso il Registro, per il registro lascia spuntate tutte le voci, acconsenti al bachup quando richiesto. Quando hai finito rifai una scansione con HJT e posta il nuovo log.
Penso che il pc dovrebbe velocizzarsi. Dimmi anche come ti connetti a internet.
Io sono in montagan e non sempre riesco a collegarmi.
Ciao

Va bene tutto a posto. Non mi hai detto se il pc è migliorato.
