It's a Triple Defense Firewall™  NEW 

• Layer 1: Protects your computer from Internet threats. Blocks hackers from gaining access to your computer by making it invisible to others online; prevents spyware from sending your personal information across the Internet.
•  NEW!  Layer 2: Protects your computer’s programs. Monitors and stops spyware and malicious programs from attacking legitimate programs; automatically disables harmful programs when they attempt dangerous activities.
•  NEW!  Layer 3: Protects the operating system. Guards the core registry and file systems; prevents spyware and malicious programs that may already be on your computer from causing damage or slow-downs.

It's an invisible shield.

Your computer "disappears" from hacking attempts, probes, and "pings"—if they can't see you, they can't harm you. Yet it doesn't interfere with normal PC use—or degrade your system's performance.

It's essential email security

• Inbound MailSafe automatically quarantines suspicious email attachments, preventing them from auto-launching or being opened by accident.
• Outbound MailSafe automatically monitors outgoing email and halts messages with potential viruses before they're transmitted. Prevents worms and viruses from sending infected emails to everyone in your address book.

It's an ad blocker.

ZoneAlarm Pro blocks annoying popup ads when you're surfing, so you avoid download delays they cause. And it's of course designed to work with all popular browsers.

It's a hacker stopper.

Every day, hackers design programs to crack hundreds of thousands of computers. Yours could be one of them today. ZoneAlarm Pro stops both these random and targeted hacker attacks, by blocking all your PC ports against attacks, and by rejecting attempts to take control of your PC.

It's a criminal reporter.

ZoneAlarm Pro gives you clear, easy-to-understand hacker reports so you can see the nature and severity of Internet threats specifically targeted to your computer. And should you choose to do so, you can use these reports to alert authorities, so serious hackers can be tracked.

It's a program controller.

The last thing you want is someone else taking charge of your computer for nefarious purposes when you’re not even using it. Good news. ZoneAlarm Pro prevents these viruses and rogue programs from sending your data to hackers by giving you complete control over which programs have access to the Internet—and under what circumstances.
