TorChat is a basic and portable freeware instant messaging application which allows you to chat securely with other people. The TorChat network is peer-to-peer with a decentralized design, similar to Gnutella. This decentralized network gives you high anonymity and being portal, does not leave any traces on your system.
This is actually the Windows version, but the developer also provides a version for Linux.
TorChat is licensed as Freeware for Windows (32-bit and 64-bit) operating system / platform from instant messaging software without restrictions. TorChat 0.9.9.553 is available to all software users as a free download (Freeware). Though this program tested positive for virus tests, some people don't view it as a virus or malware. This could mean toolbars or system modifications.
Compatibility with this software may vary, but will generally run fine under Microsoft Windows 8, 8.1, 7, Vista and XP on either a 32-bit or 64-bit setup. A separate x64 version may be available from Bernd Kreuss.
