Enable Real-Time Antivirus Protection in Windows Security

Since Microsoft Defender's iOS VPN and Windows antivirus are separate features, you need to verify that standard real-time protection is active on your Windows PC.

Open Windows Security

Click the Start menu on your Windows desktop, type 'Windows Security', and click the app icon to open it.

Navigate to Virus & Threat Protection

On the left-hand sidebar or the main dashboard of the app, click on 'Virus & threat protection'.

Access Protection Settings

Scroll down to the 'Virus & threat protection settings' section and click on the 'Manage settings' link.

4
Turn on Real-Time Protection

Locate the toggle switch for 'Real-time protection' and click it to turn it 'On'. This ensures your PC is actively scanning for malware.
