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

### REPLY:
When a computer is infected with malware, it can exhibit various signs such as sudden loss of internet connectivity, files being encrypted or locked with a ransom demand, unauthorized access to personal files or accounts, or even strange behavior like the webcam or microphone being activated without user consent. This information can be used by attackers to gain unauthorized access to sensitive data or carry out surveillance activities.
