SSKC

From the documentation:
"SSKC is a stealth key logger, that can log keys typed in all windows except in DOS boxes including keys special 1s too like function keys, tabs etc..
'Stealth' here means that a normal user will not be aware of the key logger, and its presence will not be revealed to the user even if he press CTRL-ALT-DEL!
You cannot close the key logger in any NORMAL method that is available in Windows. SSKC, is still in the development stage, the keylogger can be detected by a 'well designed' KeyLogger Tracer!
This is the first public release of SSKC, the first prototype of SSKC needed an external DLL file, which i have seemingly got rid in the latest public release. SSKC, shall log all key strokes to the file C:KEY.VxD without any encryption or compression!
There is no SMTP support for e-mail logged key strokes though its under development at the time of writing this file."
