What a keylogger do?

It traces all your keystrokes, and sometimes screenshots of your display and sends the information to the email id of the desired person frequently. It is very harmful since it can capture our username, password and other personal information.

There are software and hardware keyloggers. It is pretty easy to find hardware keyloggers : check the keyboard cable connected to the PC, and observer is there any extra connectors between your PS2 or USB connector and port, and remove it.
Software keyloggers are very harmful and very difficult to find out.

A keylogger is a harmful program that runs almost invisibly as a low level system process. Usually started up when your computer is booted - so there is no way of you detecting it - this program logs all the keys that you type and then sends that information out to the person who infected you with the keylogger.

Keyloggers are extremely dangerous and can be used to steal personal information such as your social security number, credit card number, and passwords to just about everything. This may lead to identity theft or theft in general. Keyloggers are especially dangerous to anyone who uses online cash sites such as PayPal for a large amount of money.

When you suspect that you are infected with a keylogger, do NOT type any personal information. Even if you are typing in a normal word document, the keylogger still keeps track of everything you type.

Alternatively, if you suspect that keylogger is installed and you want to type your username and password with an immediate requirement, use on screen key board instead. This is a very good tool to overcome keylogger, since keylogger trace only the key strokes of hardware keyboard.

Go to run à type osk à hit enter; now you will get on screen keboard.

These days some of the websites, especially banking websites, started adding onscreen keyboards on their website, to prevent possible threat of key logging.
But email web portals and similar websites not yet started providing this option.

Doing this opens up a keyboard on your screen so that you can click whatever letter you would like to type. Since a keylogger does not track where and what you click, this helps you to get around it in times of urgency. Typing with the on-screen keylogger is a great hassle. The only alternative is the remove the keylogger completely.

Before you can destroy the keylogger and make your compute safe, you will need to detect it. Detecting a keylogger is not easy. It can be installed in over a 100 places on your computer, usually located in one of the system files. However, there is a much easier way to detect if a keylogger is running or not. Right click on your menu bar and click Task Manager. Alternatively you can press Ctrl + Alt + Del. You should be looking at all the applications you are running at the moment. Click the tab that says Processes. This gives you information about all the programs, hidden and visible that your computer is currently running.

Unless you know a lot about which processes the computer runs and does not run you will have trouble figuring out what you are looking at. The name of each process is under Image Name. The keylogger will show up on the list of processes as well as many other programs and background processes. However, you may not be able to distinguish between the different processes.

You will need to know which process to end before you can stop the keylogger. There are many sites available on the Internet that provides a vast amount of information on each and every process that you may encounter. One of these sites is Liutilities. This site provides some background information on each process as well as telling you the author and which program it is part of. One of the best features of this site includes a recommendation about what to do with that process. Most of the time, the process you look up will be harmful and simply part of the operating system or another program you are running.

Another fantastic site for information on processes is Neuber. As with Liutilities, Neuber gives you background information on that process. A special feature they have is user created comments. Anyone can rate a process in terms of its security a leave a comment about how to deal with the process. Generally, these comments are very accurate. Neuber also provides a 'security rating' for each process based on the average rating by users.
However, some find it hard and long drawn out to research each process individually. Thankfully, there is a program called Security Task Manager that is free to download. It will display information about each of the processes that are currently running, as well as telling you if they are dangerous or not. You will immediately be notified should anything harmful come up. Produced by Neuber, the program also shows the security rating and a random comment made by a user for each process. This program does have its disadvantages though. Processes that the program has never encountered before are not given a security rating or a comment. It is therefore advised that you research these processes individually.

Once you have found the harmful process, click the process and then click the 'End Process' button towards the bottom right. The process you have selected should be terminated immediately.

Once this is complete, you should be safe until you reboot your computer. If you do not delete the keylogger, upon rebooting your computer, the keylogger will start up again.
Once you have stopped the keylogger, run anti-virus and spyware checks on your entire computer. Some free virus scan utilities that are recommended are A2, Dr. Web and AVG. However, highly advanced keyloggers such as TypeAgent, KGB, and SpyOutside can often slip through these scans and remain undetected.

If the anti virus scans fail to show any result, you will need to manually detect and delete the keylogger. Keyloggers are usually located in the system files, so do not delete anything that you aren't 100% sure is the keylogger. Doing so may lead to errors in other areas of the computer. Go to 411-spyware and search for the type of keylogger that has infected your system. If it is listed, there should be instructions about how to manually remove the keylogger.
A great way to check if the keylogger has been completely removed from the system is to reboot. Remember the name of the keylogger's process and reboot the computer. If the process is not there when the computer has rebooted, you are safe.
