### REPLY:
When a computer system is infected with malware, there are several telltale signs that can indicate the presence of malicious software. These include sensitive personal information being stolen, such as passwords, credit card numbers, or banking details. Other signs may include unauthorized access to the system or network, data encryption and ransom demands, or the system being used for illegal activities such as launching DDoS attacks or distributing illegal content.
