From the doc: 'This is the best and most advanced keylogger you will ever use. Not only does it log normal keys, it logs the keys that most keyloggers miss, such as the keys on the num pad and enter,backspace,alt,ctrl,shift,mouse buttons, EVERYTHING (I mean every key!!!!!!), all of the F#s.NOt only does it do that, it will detect all of the open window names and save that and the text that was typed into that window all in a hidden DLL!!!!(open the dll with Notepad) This is awesome, it uses not even 1percent of resources, and it will automatically add itself into the startup part of the registry. It will also give you the time and date that it was entered, the window, and the size of the file(dll). You can never see the window, it justs runs hidden until your comp is shut down, then it will start as soon as Windows starts. All you have to do is open the dll to see whatever you want. It's also hidden from the CTRL ALT DELETE screen(2000,XP only) All of this and it's only 40k. It also has the classic dos style icon so you can put it in the windows directory to disguise it.'
