The Personal Secure Disk (PSD) is a secure section of your hard disk
where you can save files. You can only get access to the PSD via
password or fingerprint authentication.
Once setup is finished, you can go to the ProShield Console to
manage your computer or make changes to the settings.
Use the menu in the left-hand pane to make changes.
