Symptoms

Likely causes
- CommonAn app running in the background is using the cameraChat apps, browser tabs, or background utilities can access the camera without a visible window open.
- CommonApp didn't fully close and still holds the cameraSome apps keep the camera reserved even after the main window is closed, especially browsers with an open call tab.
- PossibleOperating system indicator behaving normally during startup or driver checksSome systems briefly flash the camera light during boot or driver initialization as a hardware check.
- Less commonMalware or unauthorized remote accessIn rare cases, malicious software can access the camera without your knowledge.
What to do
- Check your taskbar/dock and Task Manager (or Activity Monitor) for any app that might be using the camera, especially browsers and chat apps.
- Close all browser tabs and apps that could use video calling, then see if the light turns off.
- Check system camera privacy settings to see which apps have been granted camera access, and revoke ones you don't recognize or use.
- Restart the computer, which forces all apps to release hardware access.
- Run a reputable antivirus/anti-malware scan if the light continues turning on with no identifiable app cause.
- Consider a physical webcam cover as a low-effort precaution regardless of the cause.
- If concerned about a specific compromise, change your important account passwords from another trusted device as a precaution.
