block access to unauthorized USB drives USB Block enables you to prevent unauthorized storage devices from being used on your computer. This includes USB Flash drives, external drives, non-system drives, CDs/DVDs as well as other portable storage devices. Each time a new device is connected and accessed, the user is prompted for the authorization password, otherwise access to the drive is denied. You can add your frequently used drives to a list of authorized devices, which eliminates the need to enter the password for the same device in the future. Other features include logging of hack attempts, support for Safe Mode, stealth mode and device usage reports. Copyright Snapfiles.com
