The name of this software, 'MyUSBonly', is the best to describe what this program does. It is a software meant to prevent others from stealing you files through your computer's USB ports. The program is very easy to use because after it's been installed you can't use any USB memory stick until you add it to the white list. The program resides in your system tray and nobody can access it because it is password protected. In the trial version I wasn't able to change the password as it was written on the 'USB Setup Window'. While testing the program I've tried to force the program to close but even if it disappeared from the Task Manager it was still running in the system tray and the effects were the same. I was impressed by this program because it is very useful if you want to protect your data from being steal. You can even configure the program to send you an email each time a device is connected, disconnected, or both. An USB device can connect to your computer in two ways: if you allow the connection each time it is plugged in or any time, if you added it to the white list.
