What are some common signs that a computer might be infected with malware?

### REPLY:
One common sign of a malware infection is the presence of a keylogger, which can record and transmit all keystrokes made on the infected computer. This can result in the theft of sensitive information such as passwords, credit card numbers, and personal data. Additionally, malware can also enable remote access to the infected computer, allowing attackers to control the system and potentially steal or manipulate data. It is crucial to have robust security measures in place to protect against such threats.
