What are some common signs of a malware infection on a computer?

### REPLY:
One sign of a malware infection is the presence of a keylogger, which can record all keystrokes made on the infected computer, including passwords and sensitive personal information. Another indicator is the sudden appearance of ransom notes or demands for payment. Additionally, if you notice your webcam light turning on unexpectedly, it could be a sign that your computer is infected with malware that is spying on you.
