your malwarebytes log say "NO ACTION TAKEN"  "Nessuna azione intrapresa" 
did you not click the "remove selected" button after scan ?

Thanks a lot for reply. I'm sure he gave the command to remove after the scan. I do not know why the software did not delete the selected items. Here there is the log OTL.
Thanks again, I do not know aswMBR.
Forgive me for my poor english...
