One sign that a computer may be infected with malware is the presence of a keylogger. Keyloggers record keystrokes and can capture sensitive information such as usernames, passwords, and credit card details. They can also capture screenshots or record audio and video from the victim's device. Attackers can use this information for identity theft, financial fraud, or other malicious activities.
