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

### REPLY:
One of the major indicators of a malware infection is the presence of keyloggers. These malicious programs record every keystroke the user makes, thereby capturing sensitive information such as passwords, credit card details, and personal messages. Additionally, malware can also capture screenshots, record audio or video, and even activate the webcam without the user's knowledge or consent. These activities can be used for various malicious purposes, including identity theft, financial fraud, and blackmail.
