Some common signs of a malware infection on a computer include the presence of keyloggers, which record keystrokes and can capture sensitive information such as passwords and credit card details. Another sign is the appearance of fake antivirus alerts, where a pop-up window claims that the computer is infected and prompts the user to download a fake antivirus software. Additionally, ransomware infections often display a ransom note demanding payment to regain access to encrypted files. It is crucial to protect your computer and regularly update your antivirus software to prevent and detect such infections.
