### Comment
> **Title:**
> AdGuard Parental Controls Stop Blocking After Browser Extension Removal (Arc Browser on Windows)
>
> **Describe the bug**
> AdGuard Parental Controls have stopped blocking websites on my blocklist. This issue began shortly after I installed and then removed the AdGuard browser extension on the Arc Browser (which is Chromium-based). The app’s settings appear correct, but the blocklist is not being enforced.
>
> **Steps to reproduce**
> 1. Install AdGuard app on Windows PC
> 2. Enable Parental Controls and add websites to the blocklist
> 3. Install AdGuard browser extension on Arc Browser
> 4. Remove the AdGuard browser extension
> 5. Attempt to access a website that should be blocked
>
> **Expected behavior**
> Websites added to the Parental Controls blocklist should remain inaccessible, regardless of the browser extension status.
>
> **Actual behavior**
> Websites on the blocklist are accessible without restriction.
>
> - **Reinstallation:** Reinstalling the AdGuard app did not fix the issue
> - **Not account-related:** Parental Controls work correctly on my laptop with the same account and settings
>
> **Additional context**
> - The issue seems isolated to my PC.
> - I suspect the browser extension may have altered settings that interfere with DNS filtering or parental control enforcement.
> - Other AdGuard protections (e.g., DNS filtering) still appear to function normally—only the Parental Controls blocklist is affected.
