Protect yourself from hackers. Secure your PC with a 100% free firewall download. Sunbelt Personal Firewall (SPF), previously known as Kerio Firewall, was called "our favorite" by PC Magazine.

The Windows Firewall (both XP and Vista) is worse than useless, it gives you a false sense of security. Why? It only filters incoming traffic. That means if malware has compromised your PC, it is able to send out all your personal info. That's right; the Windows "firewall" does not stop that! But SPF...

• Supports Windows XP and Vista
• Filters both ingoing and outgoing traffic!
• Keeps hackers out and your private info inside.
• Works great with VIPRE Antivirus + Antispyware
• Easy to use and does not slow down your PC!
