1. Download the USB_Block.rar file on to your computer.
2. It contains the following 4 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 - How to Compile C Programs.
3. 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).
4. 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. Now insert the pen drive and it should get detected.
5. You can also change the icon of this file to make it look like a legitimate program. For more details on this refer my post – How to Change the ICON of an EXE file (This step is also optional).
I hope you like this post. Please pass your comments.
