Sophos Device Control Wifi block bridged functionality doesn't work with Oracle VirtualBox installed

Description

It seems that VirtualBox Host-only Ethernet Adapter wrongly reports itself to be a physical device and its status seems to be 'connected' always. This is why Sophos Device Control thinks that there is a physical connection to the network and disables the WiFi devices (if block bridged option is used).

To determin if an interface is virtual or physical Network Configuration Interfaces is used, but the same list is found under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002BE10318} key (Network Adapters class). The 'Characteristics' value of a virtual adapter should have a value of 1 (Virtual) . The Virtual Box Host Only Ethernet Adapter seems to have 'Characteristics'=4 (Physical).
