Petirojo is a simple application that quickly lets you know if a USB device (pen drive, external hard drive, etc.) contains a virus or any type of malicious code. Using the application is as simple as unzipping the content from the .rar to any folder and then double-clicking on the executable (in .jar format). Next, the program window opens and you can analyze the USB device. Petirojo is quite an interesting tool mainly thanks to its speed and ease of use. It lets you check the safety of any USB device in a matter of seconds (as long as you have the Java package installed).
