Where keylogging comes from
Keyloggers are a type of activity-monitoring software that is installed on your computer without your knowledge. The most common ways of doing this are through phishing, social engineering, bundling the keylogger with other software or downloads on file-sharing sites or installing it when you open an email attachment.
How to recognize keylogging
Detecting keyloggers is difficult since they’re designed to stay hidden. But there are some signs to look out for, such as slower than usual web browsing, mouse or keystrokes that “stick” or don’t show up on the screen as what you typed, or getting error screens when loading graphics or web pages.
