Antirun is a small application that makes it much easier to manage your USB storage devices. Once you have it running, the program window will always appear when you insert one of those devices into your computer. It will alert you if the device contains any kind of malicious elements, and gives you the option to open it, view the disk information, or safely remove it from your system with just a click.
If you have more than one thing connected to your computer, the window will display a series of tabs for pendrives, portable drives, and memory cards so that you can comfortably switch from one to another.
Finally, Antirun can also be used to prevent any of those drives from running automatically when they are connected to your system. In fact, that's the function that gives the program its name.
