Zero Footprint Crypt 4.3.1 encrypts/decrypts, and displays many common file types. It provides six encryption algorithms for viewing common unencrypted image files and can even create self-decrypting encrypted files for those without the software. This freeware is superior to a number of expensive file-encryption utilities and is designed for any level of user.


Actual Keylogger 2.4 allows you to record every keystroke typed on your system and is absolutely free. It's pretty well-equipped and reasonably stealthy, especially for a freeware program. You can conceal its folder, disable its record in the Add/Remove Programs dialog, hide its shortcuts, encrypt its logs and password-protect its settings. The best free software of its kind!

From SpeedApps:
The File Guardian utility is an advanced tool to see changes to a file(s) in a particular directory. Whether it is a log file creating by some batch processing program or a report file generated by a reporting engine. All you have to do is specify the path and the type of file(s) you are looking and this program will automatically fire events on creating/renaming/deletion of files.

SnoopFree Privacy Shield is great, but can only be used in Windows XP, sorry. It will protect you from keyloggers and activity monitors.
