Firewall & Security - ZoneAlarm Free
ZoneAlarm Free - connecting to the Internet is like opening a door to your computer. Through that door, you can easily go online to shop, read the latest news, send e-mail, and more. But an open door also allows hackers to easily gain access to your PC. To protect yourself from hacker attacks, you need a PC firewall. In effect, a PC firewall shuts your computer's door to hackers, allowing only authorized traffic to flow through. Antivirus software protects you from known viruses and can help clean up after a virus attack. But only a PC firewall can block unauthorized access to your Internet-connected computer and protect against both known and unknown malicious software and Internet threats. At the same time, a PC firewall allows your computer complete, unrestricted access to the Internet.
