Google is sort ample to inform you that it might't scan the file for security, but must you ignore that warning, you'd proceed to down load the XNXubd VPN Browser .copyright file and put in it with your device. I have contacted XNXubd for remark, but haven't acquired a response. https://github.com/XenoxArefia/www-xnxubd-vpn-browser-com-download/
