USB drives have seen a surge in use, mainly due to their combination of great storage capacity, increased transfer speed, and portability. While this proliferation has been beneficial in most cases, sometimes sticks can become vectors for severe digital infections. To prevent such cases, one can employ programs such as USB Protection Tool, a utility that allows one to protect USB units against writing.

This prevents users from tampering with the files on the device and other protective measures include the disablement of autorun functions - thus effectively cutting off potential hazards, but also the ability to prevent the registry editor from launching. As one can see, some of these features target the USB drive while others target the system.

As such, it can be said the program has a two-step protection scheme, one oriented at the USB device and one at the system. Corresponding buttons are in place, and one can lock USB devices with a simple press of a button. Alternatively, the “One-Click Protection” option ensures sticks and other devices cannot connect to the computer.

If required, users can customize their security measures by opting for individual tools, such as the ones mentioned in the second paragraph. It should be noted that any drives already connected to the computer must be reloaded or ejected and reconnected, for any changes to take effect.

A master password can also be created, to ensure unauthorized users do not remove protective measures already set in place. Whenever attempting to alter security settings, a passkey prompt is displayed and failure to provide correct credentials will result in no changes being saved.

To conclude, USB Protection Tool is a viable tool for anyone who regularly relies on USB drives to transfer information around. It can be used as a good warding off utility and one can even institute complete USB locks.
