The Pest Patrol component is a great addition to an already solid firewall. Same price at most firewalls with no anti-spyware component. Pest Patrol works well...updates can be downloaded within the program and 'pests' can be quarantined or deleted. Firewall performance is comparable to ZA, Mcafee, and others.

I've been using Privatefirewall since v2. Combined with PestPatrol offers excellent combined solution for protection from hackers and spyware. Super easy to use, very effective and great price.
