How Keyloggers Work and Why They Are Harmful

By their name alone, you would not detect that keyloggers are programs that do harm

. You would just think that they just help you log into a network or site. But, no. They have malicious and destructive intents. Though, you can easily protect yourself from keyloggers by installing the best antivirus firewall software for your computer.

Yet, even if your computer is armed with the best antivirus firewall software, you still need to understand what keyloggers are and how they work. It is important to know your potential enemy, and a very sly and intrusive enemy at that.

The general mode of operation of keyloggers is that of tricking computer users into downloading the keylogging software. A user is made to believe that her or his system has been attacked by a virus. These scam pop-ups then purport to offer assistance. They pretend to present options which the user could take. One option is going to a website and downloading an antivirus scanner. Once the user gets hold of it, the keylogging software is installed in the computer unit. After this, it then does its magic and work its way through the system.

These nasty computer programs are called keyloggers because they detect and take note of the keystrokes that the user makes on the computer keyboard. Keystrokes could include the key sequences for your passwords, banking accounts, email addresses, or other important accounts you use for communication.

Some keyloggers employ another destructive method: by taking control of your keystrokes, or even mouse strokes. They disable you from controlling your mouse and your keyboard. Involuntary clicking and typing of letters are accomplished by these loggers. At the least, you may enter websites that are not safe. This may cause further damage to your computer.

Some serious cases caused by keyloggers include online robbery. Keyloggers can take note of your online banking accounts and passwords. With this knowledge, they intently infiltrate your account and do whatever they wish with your money. Without your knowing, cash transfers to other accounts may happen within a matter of minutes--long enough before you could find out that you've lost all your cash.

To stay clear of keyloggers and other forms of information-stealing software that can infiltrate your computer, you must secure your system with the best antivirus firewall software, especially one that is capable of detecting keyloggers.
