KeyScrambler – KEYSCRAMBLER.EXE
Keyscrambler.exe and keyscramblerie.dll install with the QFX Software KeyScrambler Personal and KeyScrambler Professional. KeyScrambler was designed to defeat keyloggers by encrypting your keystrokes at the keyboard driver level. When the encrypted keystrokes reach your browser, KeyScrambler then decrypts them so you see exactly the keys you've typed. Keyloggers can only record the encrypted keys, which are completely indecipherable.
If you want this type of protection, you'll need to leave these files in place. More information can be found at http://www.qfxsoftware.com/products.htm.
