Hi Stephen,
Thanks for posting your concern in community forum.
AVG Secure VPN is an application that enables you to connect to the internet via secure VPN servers using an encrypted tunnel. Secure VPN can be used any time you want to connect to the internet with extra security and privacy, and is especially recommended when you are connected to a public or unsecured wireless network. AVG Secure VPN has servers in several locations, which means you can bypass geolocation restrictions, as well as access your favorite content while traveling.
To scan your PC for threats and viruses, you need to install AVG Internet Security program and purchase a paid subscription to unlock the paid features.
