Ciao poker, c'è qualcosa da eliminare:

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.

Poi fai una pulizia con Ccleaner compreso il Registro.
Fai anche una scansione COMPLETA con Malwarebytes, dopo averlo aggiornato, elimina quello che trova.
