Once you have confirmed (or strongly suspect) something has accessed your webcam or microphone without permission, work through these steps in order.
Step 1: Revoke permissions immediately
- Settings → Privacy & security → Camera — turn off Camera access entirely as a quick kill switch
- Settings → Privacy & security → Microphone — do the same
- Re-enable each only for the specific apps you actually trust (e.g. Zoom, Teams)
Step 2: Remove suspicious apps
If a specific app showed up in your privacy logs that you did not install or do not trust:
- Settings → Apps → Installed apps
- Find the app, click the three dots, choose Uninstall
- Reboot
If the app refuses to uninstall, treat it as malware and follow the How to Detect Viruses on a Windows PC with Malwarebytes guide.
Step 3: Rule out remote access tools
Webcam and mic spying is a classic symptom of remote access tools (RATs). Run through the How to Find Remote-Access Tools on Your Windows PC checks before you call this resolved.
Step 4: Add a physical layer
- Stick a webcam cover (or a small piece of opaque tape) over the lens when you are not on calls
- For external USB webcams: simply unplug them when you are not using them
- For laptop microphones: there is no easy physical mute, so rely on Windows-level revocation and a clean OS
Physical webcam covers cost less than $5 and remove the problem entirely. Highly recommended on any laptop.
Step 5: Verify it's stopped
After 24 hours, return to Settings → Privacy & security → Camera and Microphone. The Recent activity list should show only apps you actually used. If anything new appears that you cannot explain, repeat the steps and run a full malware scan.
