What are some common signs that a computer may be infected with malware?

### REPLY:
One possible sign of a malware infection on a computer is the sudden appearance of a new user account with administrative privileges. This could indicate that an attacker has gained unauthorized access to the system and is attempting to maintain control. Additionally, if the computer's webcam or microphone starts activating without user input, it could be a sign of malware that is remotely accessing these devices for surveillance purposes.
