Recording information about keystrokes (interception) is tracking the pressing of each key on the user’s computer keyboard without his knowledge.
A keylogger can be hardware or software and used as a legitimate individual or professional tool for IT monitoring.
However, the interception of keystrokes can also be used for criminal purposes.
Most often, a keylogger is malicious spyware that is used to collect confidential information, such as passwords or financial data, which is then sent to third parties for use for criminal purposes.
But the best protection is the installation of a good antispyware product that protects against keyloggers, or a full-fledged security solution with functions to prevent the use of keyloggers on the computer.
