There was a download of WinDefender 2.2 on the developer's website when we last checked. We cannot confirm if there is a free download of this software available. The program lies within Security Tools, more precisely Privacy. This software is an intellectual property of RTSECURITY. We recommend checking the downloaded files with any free antivirus.
From the developer:
WinDefender provides you with a service to keep your
valuable files encrypted on your hard drive. When you
want to use them you enter the password and then
WinDefender will automatically (on-the-fly) decrypt them
when reading from the hard drive (floppies, cd-rom, etc.)
and encrypt them when writing to.
You may want to check out more software, such as Keylogger Hunter, #1 Anonymous Proxy List Verifier or WildBlue Security Center, which might be similar to WinDefender.
