What are some common signs of a malware infection?

### REPLY:
A common sign of a malware infection is unauthorized access to personal or sensitive information. Malware can collect data such as login credentials, credit card information, or even keystrokes, without the user's knowledge. This information can then be used for malicious purposes such as identity theft or financial fraud. Other signs of a malware infection include ransom notes demanding payment in exchange for restoring access to encrypted files, or the appearance of new and unfamiliar icons or software on the desktop.
