Keyloggers are trojans, a form of backdoor entry into your computer. What happens is every keystroke you press, any form you fill out will be logged, such as passwords credit cards etc. Then the keystrokes get saved into a file that is either sent back to the hacker through various ways or saved in your computer for later delivery to the one who implemented it. You can recieve a keylogger from an infected website, or by opening up a file that is infected with it. Also, you may be exposed to one if your computer is easily exploited and you have security holes in it. Other means of becoming infected with a keylogger is if somone physically inserts a cd or floppy disk into your computer and downloads it when you are unaware. The best protection from keyloggers are to have your computer updated and antivirus software installed. Protecting your computer from keyloggers is an essential step in maintianing security for yourself and anyone using your computer.

thank you for the information. can antivirus eliminate keyloggers? or do i need special programs for it? and i once read in an article that keyloggers are the size of the thumbs. what does that mean? can i physically remove it? does it means that somebody can actually put it in my hardware? thanks.

Actually keyloggers, once installed, can be hard to remove as experienced coders write new ones to suite their needs, and the one you have been infected with may be undetectable by an Antivirus. They may be bigger or smaller depending on the functions of a keylogger, but detection is sometimes impossible. Getting a powerful firewall to prevent unauthorized acces to you computer is essential in this case, and you should have one on your computer installed along with an Antivirus software. That way, even though you get a keylogger on your computer, the intruder would not be able to access the valuable information he set for, and your computer would be safer from more attacks. The only other way someone could obtain that information is by physiclly accessing your computer, and you can prevent that by password protecting your files and encrypting files as well as putting passwords on startup in your BIOS, the thing that loads just as you turn on your computer.
