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

### REPLY:
When a computer is infected with malware, the attacker gains control over the system and can monitor the user's activities, steal sensitive information such as passwords and credit card details, or even use the computer as part of a botnet. It is crucial to regularly update antivirus software, use strong and unique passwords, and avoid clicking on suspicious links or downloading files from untrusted sources to prevent malware infections.
