Support for both Windows Vista and IPv6 are in release candidate phase as of January 2009.


As with most other desktop firewall software for Windows, Version 2.0 is installed as a kernel-level filter in Windows 2000 and later, giving the application greater access to the Windows networking stack and greatly improving overall performance. The new design caused the application to consume significantly less processing power and memory while running. In order to resolve speed and resource issues, Version 2.0 was re-engineered and re-developed in C++. The installation procedure was also simplified, no longer requiring a system restart and driver installation. Version 2 enabled support for more protocols (TCP, UDP, ICMP, etc.), multiple block lists, and automatic updates. The development of version 2.0 was lead by Cory Nelson, and aimed to resolve many of the shortcomings of Version 1.
PEERGUARDIAN 2019 FOR FREE
The original version was released for free and the source code was made available under an open source license.Īfter 7 months of development, in February 2005 Version 2 of PeerGuardian was released as a beta. By December 2003, it had been downloaded 1 million times. The original PeerGuardian (1.0) was programmed in Visual Basic and quickly became popular among P2P users despite blocking only the common TCP protocol and being known for high RAM and CPU usage when connected to P2P networks. The first public version was released in 2003, at a time when the music industry started to sue individual file sharing users (a change from its previous stance that it would not target consumers with copyright infringement lawsuits). Development on PeerGuardian started in late 2002, led by programmer Tim Leonard.
