Antivirus misses 1 in 3 new viruses and does not block other kinds of hacking. That's why you also need a strong firewall.
ZoneAlarm Free Firewall blocks intruders and makes you invisible to hackers; stops attacks that antivirus and your default Windows security misses; blocks new viruses from sending your data (like passwords or social security numbers) to hackers; detects spoofed programs; stops hacking disguised as harmless network transmissions; works seamlessly with antivirus programs; works automatically--no expertise required; includes security for safer Web browsing.
What's new in this version:
In version 9.2 alerts are reduced by 97%; community-powered threat detection blocks the latest malware; Identity Protection Checkup verifies if your identity is at risk (U.S. only); site check and phishing detection blocks dangerous Web sites; Secure Online Backup (2GB Free) helps you restore any lost data.
