Understanding Avast SecureLine Virtual Adapter Behavior
The Avast SecureLine Tap Adapter v3 acts as a virtual network interface that routes your traffic through the VPN. When Windows disables this adapter, the secure tunnel cannot form, and your apps may switch back to the regular internet connection.
Monitoring the status of this adapter helps you identify VPN issues early. Windows Device Manager, Network Connections, and Avast user interface all provide visibility into whether the adapter is enabled, and they guide you toward corrective actions when it is disabled.
