From Syed Ghulam Akbar:
USB Disk Manager is small and easy to configure Windows utility which helps you use your USB disks more securely. Make your USB removable disk secure by write protecting them. Make your system secure by denying execution access from the removable disks. Disable all your USB removable disks to disallow read and write on the USB removable disks. This way user will not be able to transfer files to and from the USB disks to your machine.
Now a days one of the common way of the software virus infection and spread is through the use of USB disks. That is, the virus tries to automatically copy itself to and from the USB disks to the host machine. USB Disk Manager helps you avoid these situations by making the write projecting the USB Disks so that virus can't copy itself to new USB Flash disks, and also disables execution of the virus files directly from the USB disks thus avoiding the automatically copying and spreading of the viruses from the USB disks to your machine.
