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

### REPLY:
When a computer is infected with malware, you may notice a significant decrease in performance, frequent system crashes, and sudden loss of data. Additionally, you may experience a high network traffic as the malware communicates with its command-and-control servers. In some cases, the malware may disable antivirus software and firewall, making it difficult to detect or remove. Furthermore, sensitive information such as login credentials, credit card details, or personal files may be stolen and used for malicious purposes.
