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

### REPLY:
When a computer is infected with malware, you may notice unusual network activity, unauthorized access to sensitive files, or the creation of new user accounts. The malware may also disable antivirus software, modify system files, or encrypt files and demand a ransom for their release. Additionally, some malware strains are designed to capture sensitive information such as passwords, credit card details, or personal data, which can be used for identity theft or financial fraud.
