Key loggers are used to capture personal information.

Key logger viruses are computer software applications used to track various pieces of information on specific computers.

Someone looking to harvest passwords or account information can install key loggers onto any number of computers to gather needed information for identity theft. Understanding their function and how to locate them on a computer will help keep this virus from causing serious damage to personal information.

Key logger viruses can easily be identified by the file extension within a file such as .exe or .app.
