What are Keyloggers?

Like you said, its a virus that is installed in your system stealthily and it tracks what you type... Meaning, if you are visiting your webmail or your bank account, keying in your username and password will be tracked by the keylogger and in turn feedback to the hacker...The hacker will be able to steal your username and password, and your account eventually.. Install an antivirus software, update it and do a thorough scan on your system

Hi mishastar, A keylogger is a program that sits quietly on your PC and records the sequences of key presses that you enter on your keyboard. At some point, the keylogger program might then send what it has recorded from your keyboard activity in a file to a server on the Internet - without you even being aware that it has happened. The info that keyloggers are designed to capture is typically stuff like passwords and account numbers - credit card details, for example. The keylogger program sends this info to someone who will then try to use it to get your money, or to buy things with your money. You can install security software which will search for and remove problems like keylogger programs. You might like to try [ http://www.lavasoft.de/ ], [ http://spybot.info/ ] or [ http://www.avast.com/eng/avast-virus-cleaner.html ], which all have free versions of their respective security applications. There are a lot of other similar programs available on the web, but you have to do a bit of searching to find what will work best for you. I hope that helps a little.

I think you had got the answer from the previous responder in this discussion. But I would like to express my opinion as well As you know, the keylogger is a software that could track all the keystrokes on the key board and send the key stroke sequence to somewhere else. This impose a great risk to the security, because if you are keying sensitive information like credit card or online banking website password, the information might be leaked to third party through the key logger program residing in the PC that you used. Therefore, you should avoid using the public computer to purchase online or login to your bank account. The keylogger not necessary in the software form. It could be a physical device attached to the PC as well. Besides, it also not necessary in virus form. It could be just a subroutine service which is launched automatically when the PC operating system starts up. I just learn yesterday that, we should use the virtual keyboard to key in sensitive information instead of the conventional keyboard. In such a way, the keylogger couldn't track what password or credit number had been keyed in.
