user196: 
I got this error connecting to blockchain.info, does anyone know what that means?

user1420: Basically, I think you have a Google Chrome extension (possibly FastSave 1.1) that is overlaying their ads with superfish's ad-serving network.
See here for reference:

Check the chrome extensions you have; disable one by one. This is a particularly unobtrusive and semi-non-harmful (to you) virus that allows a malicious developer to replace ads you view with ads they serve.
