Hello, Roger.
Thank you for choosing AVG solution for your devices. Please be informed that AVG Secure VPN is available for both Android and Windows platforms but you have to purchase them separately. AVG Secure VPN for android platform can be bought from Google play store.
I have paid for the AVG PRO Internet Security and wondering if I should add the VPN. Will it work on Android tablet as well as my Windows PC/Laptops?
Roger, Also have a look @ this Google webpage (https://play.google.com/store/apps/details?id=com.avg.android.vpn&hl=en_GB).
