Virus program to disable USB port

In this post I will show how to create a simple virus that disables/blocks the USB ports on the computer (PC). Here I use my C programming language to create this virus. Anyone with a basic knowledge of C language should be able to understand the working of this virus program.
Once this virus is executed it will immediately disable all the USB ports on the computer. As a result the you’ll will not be able to use your pen drive or any other USB peripheral on the computer. The source code for this virus is available for download. You can test this virus on your own computer without any worries since I have also given a program to re-enable all the USB ports.

1. Download the USB_Block.rar file on to your computer.
2. It contains the following two files.

• block_usb.c (source code)
• unblock_usb.c (source code)

3. You need to compile them before you can run it. A step-by-step procedure to compile C programs is given in my post. Donot compile the virus file just like that, please read my article on spreading virus through c compiler for clear compilation.
4. Upon compilation of block_usb.c you get block_usb.exe which is a simple virus that will block (disable) all the USB ports on the computer upon execution (double click).
5. To test this virus, just run the block_usb.exe file and insert a USB pen drive (thumb drive). Now you can see that your pen drive will never get detected. To re-enable the USB ports just run the unblock_usb.exe (you need to compile unblock_usb.c) file. Insert the pen drive and it will get detected now.
6. You can also change the icon of this file to make it look like a legitimate program.
I hope you like this post. Please pass your comments.
