There are two types of keyloggers.

The first is one you would personally install on a spouse's or child's computer to see what they are up to. The software runs in stealth mode (although most antiviruses pick them up) and emails you the results or stores them in a hidden folder that only you have access to.

The second (and most vicious) is received by downloading a file or visiting an infected website. These malicious keyloggers record everything you type including passwords and account numbers. They then zip up on a pre-scheduled basis and send the recording back to the source where some jerk tries to filter your banking, investment, and other online funds for him (or her) self. This is why having a good antivirus, spyware sweeper, and malware sweeper are so important.
