The high-speed Internet connection you enjoy puts you at risk of being a target for a hacker attack. The broad band advantage of being "always on" also means your computer is "always exposed"! The only time your computer is truly safe from an attack is when the pathway to the Internet is not open. The PathLock e100 NETimer secures your computer by keeping the high-speed connection physically blocked from the Internet when you don't want or need to be connected. http://www.pathlock.com/
