Keyloggers are applications that run on your background and record all your keystroke and behavior on your PC and sends a report to a hacker that planted it there. Some keyloggers are made FUD(Fully UnDetectable) so that the anti virus and anti malware softwares are not able to detect them. And although your PC seem secure, it can be sending critical information to people you don’t want.
Thats were anti keyloggers comes in. Anti Keyloggers encrypt the keystrokes you press and the application you are using. The key loggers then will only get random characters encrypted by the anti keylogger that cannot be made to mean anything. Keeping your confidential data like passwords, credit card info and other info safe from being stolen.
