Keylogger Pro 1.7
This is a low-level stealth keystroke monitoring application that secretly records and backs up all keystrokes typed on your PC.
It offers a wide variety of features, including the ability to view keystrokes remotely by having the program send keystrokes to a specified e-mail address at specified times. You can limit logging to selected users and set monitoring schedules. Additional features include an intrusion detection option that attempts to bypass spyware scanners.
The unregistered version of this program stops recording keystrokes after 30 minutes.
