### REPLY:
When a computer is infected with malware, it can exhibit various signs such as the sudden appearance of explicit or inappropriate content on the screen, unauthorized access to personal files, and even ransom demands. In some cases, malware can also record keystrokes and steal sensitive information such as login credentials and credit card details. It is important to regularly update antivirus software and perform scans to prevent and detect such infections.
