Use the suggestion above as it's pretty much all that you need to do. This warning occurs from the presence of self-signed security certificates, or a certificate your browser is unable to verify as being valid for whatever reason. The Certificate on Stoli is valid, however some browsers continue to complain about it. Additionally, if it isn't a browser issue, and if it isn't a certificate issue, it sometimes means the network you are on would be forging SSL Certificates, which is usually not a good sign. This is rare, so if you are at home this more than likely isn't the case. It is more likely at places offering Free Wireless Internet.
