Some HP laptops users came with a preinstalled program to capture the keystrokes of users, a security researcher recently discovered. The researcher, Michael Myng aka "ZwClose," discovered the keylogger software while trying to solve a keyboard problem for a friend. The software is turned off by default. After Myng contacted HP about the program, it quickly released a patch to get rid of it. "A keylogger is a very dangerous piece of software," said Lamar Bailey, director of security research and development at Tripwire.
