Keyloggers are programs or devices that record every keystroke you make. It can be used on anyone to watch and record everything they type on their PC.
It is arguably the most dangerous tool in any cybercriminals arsenal. Used to obtain logins, passwords, emails, credit card numbers, banking information, and other sensitive data.

Keyloggers have been promoted to parents and guardians to help in an effort to monitor their children’s whereabouts on the internet. However, keyloggers are considered a form of spyware. They can pull saved passwords, track websites you visit, and also pull information from your autocomplete lists.

Avoiding Keyloggers

In addition, there are various ways your PC can become infected. Cybercriminals often use trojan viruses to install keyloggers onto your systems. You can also inadvertently get them by click on links, through email attachments, or by downloading them from infected websites.
