What Are Keyloggers?

Keylogger is a hacking program or tool designed to record keystrokes typed during data input and record them in a log file. The same keylogger program is also designed to secretly send these log files to the hacker, where he/she can use the recorded data for illegal activities or sell your private data on illegal sites.

The program also monitors your movement on the web to record data related to login bank details through which the hacker can easily access our private and social accounts.

  • Frequent system crashes, and lagging of system applications may also indicate keylogger infection.
  • Additionally, you may also notice slow reaction speed from the keyboard, which indicates the keylogger infection in the system.

Next, in the tutorial ‘what are keyloggers’, you will know about the ways the keylogger program may enter the system.

How Does Keylogger Infect the System?

Keylogger program may enter your system through various channels, either online or offline means, some of which are:

  • The malware program may get installed when accessing email from an unknown source or an attachment in the email.

Next, in the tutorial on ‘what are keyloggers’, you will look into preventing keylogger programs from entering your system.

Preventing Keylogger Infection

Like other malware programs, the keylogger program can be prevented from entering if correct precautions are taken. This might protect your data from getting logged by the keylogger program for malicious purposes.

To prevent the system from getting installed/infected with the keylogger program, you can refer to some of the below-mentioned points as reference:

  • Regular antivirus scans to check any unusual activity from software or an application and prevent it from affecting our system.
