[post=235794]Creating Bruteforce Program[/post]
You mean start up on every reboot. And runs in the background...
That would fit.
Ok, here's an example. To shutdown a computer using windows you can press ctrl+alt, u, u. If I wanted my computer to shutdown everytime I pressed u,u,u, how would I go about making a program that runs automatically at the start and waits for key inputs or some other command. A decent keylogger would be another example of the type of application I would like to make.
Why do I get the feeling you are up to no good?
