What are some indicators of a malware-infected system?

### REPLY:
One indicator of a malware-infected system is the presence of keyloggers, which can capture and record all keystrokes made on the infected device. This can include sensitive information such as passwords, credit card numbers, and personal identification details. It is important to regularly check for any suspicious processes running in the background and monitor network traffic to detect the presence of keyloggers or other advanced malware.
