How can i restrict use of my webcam from malware?

## What this usually means
This is most likely a malware, browser abuse, spyware, or persistence issue rather than a normal driver fault.

## Fastest way to identify your situation
- Check whether the behavior happens only in the browser or across the whole PC.
- See whether it returns after reboot.
- Review startup apps, extensions, and recently installed software.

## Technical causes
- Browser hijack or extension abuse
- Potentially unwanted software restoring the behavior
- Startup or scheduled task persistence
- Spyware or malware tied to a recent install or download

## Exact checks to run now
- Run a full system scan, not just a quick scan.
- Check browser extensions and site permissions.
- Review startup apps and scheduled tasks.
- Remove suspicious downloads or newly installed software.

## When this is a serious threat
- The behavior returns immediately after cleanup
- Security settings change on their own
- Unknown remote-control behavior appears

## How to fix and lock it down
- Remove suspicious software and extensions.
- Clean startup persistence.
- Revoke risky browser permissions.
- Re-scan the system after reboot.

## Recommended fix order
1. Stop interacting with suspicious prompts
2. Run a full threat scan
3. Review browser extensions and permissions
4. Review startup and persistence
5. Reboot and verify

## Bottom line
This looks like a threat or persistence issue. The safest next step is to use the ASR threat cleanup flow and verify both the threat and the persistence layer.
