USB

USB is a freeware Windows tool designed to provide an extra layer of security to your USB removable drives by controlling the Autorun.inf file and thus blocking potential threats.
The purpose of the program is fairly simple, as it places an icon in System Tray and monitors USB ports for new plugged in devices.
Designed to run all the time, USB automatically renames the Autorun.inf file of any connected removable drive, just to make sure no infection that usually spreads with the help of USB devices manages to reach your computer.
Plus, the Autorun.inf file thus becomes visible to the system and the other security solutions that may be installed, including antivirus products, and allows them to perform a scan easier.
The System Tray icon allows you to check the local drives for Autorun.inf files, but also disable autorun for all system drives, while a different settings menu lets you enable messages the Tray icon, select command file and run it on removable device connection.
As said, USB is supposed to run all the time, but that doesn't necessarily mean that it slows down the system and hampers performance. It runs on low resources and works okay on all Windows workstations, becoming a great tool for both older and newer machines.
Overall, USB does what it says, but most today's antivirus and security products are already performing this task, while ensuring a high level of protection for each USB port. On the other hand, USB is very easy to use and provides a limited number of configuration options that makes it appropriate for all types of users, be they beginners or more experienced.
