This crack patches Kaspersky Internet Security 7 to allow it to be activated with any KIS6 key file. 
I have included the extremekey.key file for you to use 
but you may use any other kis6 key if u have one.   

1)Reboot computer in safe mode.
2)Add the kis7key.reg file to the registry by double clicking it.
3)Run the patch; KIS-7Crack.exe
4)Restart windows and when asked to activate kis7 choose "apply existing license key"
 and use the extremekey provided.
