As you can probably tell from the title, keyloggers are very dangerous programs. But they are programs that you do not hear about every day. They do not get the same press as a computer virus does. If you are involved in computer security then you should be very familiar with them. To the public at large, they really are still a mystery. The one thing that the public should know about them is that if they are ever able to get into your computer, then your privacy on your computer could be severely compromised. There is nothing that you would be able to do on your computer without the bad guys knowing about it. So let’s talk about keyloggers and how they are able to be this destructive.

What keylogger do?

A keylogger is a program that sits on your computer in the background and registers the keystrokes that you make. It then reports the information back to the main server that controls it. There are hardware versions of this type of program as well but these days you will mostly see the software variety. Whenever you type a letter on your keyboard, you are sending a signal that gets registered to your operating system. The operating system, after it translates it, then sends the signal back to the hardware so that the letter that you typed shows up on the screen.  So when the keylogger is sitting in the background during this time, it is taking notes of everything that is being pushed. Once the notes are taken, after a certain amount of time, it then sends it back for the person controlling the server to shift through. Once they see this information, they can use it for their own personal gains. This means that they can either sell it to scammers, or try to scam you themselves.

If you want to make sure that your system steers clear of keylogger, then there are a couple of things that you must do. The first thing that you must do is to make sure that you have an updated antivirus on your system the whole time. A keylogger is usually introduced onto your computer by a Trojan. A Trojan is a piece of malware that carries another piece of malware and delivers it to the target system. Luckily for you, an updated antivirus program will be able to catch a Trojan as well. So as long as you have that on your system then it will help keep you secured. You also want to make sure that you stay off of dangerous web sites. Questionable web sites might be able to have you catch something like this as well. Also, make sure that the links that you click are trusted and will not lead you to any bad places.

As you see there is a lot of dangers that can be picked up on the internet, even some that you have never heard of before. If you want to make sure that your system stays safe, then you need to keep aware of danger such as a keylogger. You do not want anything like this being able to sneak through onto your system.
