How does the PCguard Firewall protect me?
The PCguard Firewall scans all your Internet traffic and either allows or blocks the connection. This protects you from outside attacks. A Firewall is necessary to keep unauthorised data from entering or exiting your computer. Any computer connected to the Internet is vulnerable, but the best targets are those with high-speed, always-on Broadband connections, such as cable modems. Its fairly simple for someone to find out if they can connect to your computer and then look for files to read or damage. High-speed connections are targeted because, being always on, they are the simplest to track down and, being high-speed, can be used to do most damage.
