| Description: | Connecting to the Internet without a firewall is like leaving the keys in your car with the engine running and the doors unlocked while you run into the store. Although you may be able to get in and out before anyone notices, someone may take advantage of the opportunity. On the Internet, hackers use malicious code—such as viruses, worms, and Trojan horses—to try to find unprotected computers. A firewall can help protect your computer against these and other security attacks. |
