Generally we see in social sites people post Hack Facebook, orkut, gmail, passwords and all these things with key-loggers.
Now What exactly a keylogger ???
A keylogger is a type of surveillance software that has the capability to record every keystroke you make to a log file. A keylogger also know as keystroke logger is software or hardware device which monitors each and every key typed by you on your keyboard. You can not identify the presence of keylogger on your computer since it runs in background and also it is not listed in task manager or control panel. A keylogger recorder can record Chat history, instant messages, e-mail, and any information you type using your keyboard. The log file created by the keylogger can then be sent to a specified receiver. Some keylogger record desktop screen. Unfortunately, keyloggers can also be embedded in spyware allowing your information to be transmitted to an unknown third party.

A keylogger program does not require physical access to the user’s computer. It can be downloaded on purpose by someone who wants to monitor activity on a particular computer or it can be downloaded unwittingly as spyware and executed as part of a rootkit or remote administration (RAT) Trojan horse. A keylogger program typically consists of two files that get installed in the same directory: a dynamic link library (DLL) file (which does all the recording) and an executable file (.EXE) that installs the DLL file and triggers it to work. The keylogger program records each keystroke the user types and uploads the information over the Internet periodically to whoever installed the program.
An anti keylogger is a piece of software specifically designed to detect keyloggers on a computer, typically comparing all files in the computer against a database of keyloggers looking for similarities which might signal the presence of a hidden keylogger. As anti keyloggers have been designed specifically to detect keyloggers, they have the potential to be more effective than conventional anti virus software; some anti virus software do not consider certain keyloggers a virus, as under some circumstances a keylogger can be considered a legitimate piece of software.
Rebooting the computer using a Live CD or write-protected Live USB is a possible countermeasure against software keyloggers if the CD is clean of malware and the operating system contained on it is secured and fully patched so that it cannot be infected as soon as it is started. Booting a different operating system does not impact the use of a hardware or BIOS based keylogger.
Anti-spyware / Anti-virus programs
Many anti-spyware applications are able to detect some software keyloggers and quarantine, disable or cleanse them.No software-based anti-spyware application can be 100% effective against all keyloggers.
Why should use keylogger ?
Although keylogger programs are promoted for benign purposes like allowing parents to monitor their children’s whereabouts on the Internet, most privacy advocates agree that the potential for abuse is so great that legislation should be enacted to clearly make the unauthorized use of keyloggers a criminal offense.
