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

### REPLY:
When a computer is infected with malware, you may notice unusual behavior such as files being encrypted and held for ransom, keyloggers capturing sensitive information, or unauthorized access to personal data. Additionally, some advanced malware can disable antivirus software or hide its presence, making it difficult to detect. It is important to take immediate action to remove the malware and protect your sensitive information.
