This needs to set registry, and keys that need be set are;

Software\Microsoft\Windows\CurrentVersion\Internet Settings and the value that need to set is "WarnOnZoneCrossing" to '0' in current user registry.

Software\Microsoft\Windows\CurrentVersion\Internet Settings\Zones\3 and the value that need to set is "1601"to '0' and "1609" to '0' in local machine registry.

The code will look like

using (RegistryKey key = Registry.CurrentUser.OpenSubKey (@"\Software\Microsoft\Windows\CurrentVersion\Internet Settings", true))
            {
                if (key == null)
                {                    Registry.CurrentUser.CreateSubKey(@"\Software\Microsoft\Windows\CurrentVersion\Internet Settings");
                    using (RegistryKey newKey = Registry.CurrentUser.OpenSubKey(@"\Software\Microsoft\Windows\CurrentVersion\Internet Settings", true))
                    {
                        newKey.SetValue("WarnOnZoneCrossing", 0);
                    }
                }
                else
                    key.SetValue("WarnOnZoneCrossing", 0);
            }
            //enable submission of non-encrypted form data
            using (RegistryKey key = Registry.LocalMachine.OpenSubKey(@"\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Zones\3", true))
            {
                if (key == null)
                {
                    Registry.LocalMachine.CreateSubKey(@"\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Zones\3");
                    using (RegistryKey newKey = Registry.LocalMachine.OpenSubKey(@"\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Zones\3", true))
                    {
                        newKey.SetValue("1601", 0);
                    }
                }
                else
                    key.SetValue("1601", 0);
            }
            //enable the display of mixed content
            using (RegistryKey key = Registry.LocalMachine.OpenSubKey(@"\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Zones\3", true))
            {
                if (key == null)
                {
                    Registry.LocalMachine.CreateSubKey(@"\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Zones\3");
                    using (RegistryKey newKey = Registry.LocalMachine.OpenSubKey(@"\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Zones\3", true))
                    {
                        newKey.SetValue("1609", 0);
                    }
                }
                else
                    key.SetValue("1609", 0);
            }
