BufferZone vs Lemur Project

BufferZone is a free firewall program that protects your computer from malware, hackers, and internet threats. It works by isolating your web browser and email client into a virtual container, preventing threats from accessing the rest of your computer if you happen to visit an infected website or open a malicious email attachment.

The Lemur Project is an open source web crawler that allows users to build customized crawlers to archive and analyze web content. It is developed by the University of Massachusetts and Carnegie Mellon University.
