I tried flushing dns. Nothing. Everyone else who tried that said it didn't work, either.
People with Firefox have experienced this same thing, so even if I could get to mozilla.com to download it, which I can't

, I doubt it would help. This problem is happening with both my browsers: Google Chrome and Internet Explorer.
It's happened to so many people of different circumstances: they have different operating systems, use mac and windows, use various browsers, have different kinds of routers, live in different countries, and on and on. And it seems everyone's tried everything they can think of. They say that they touched nothing - one minute everything's fine, the next, this. It seems no one is immune and everyone is susceptible. I've been through so many help forums (but this is only one I've posted to), and no one has been able to say that they recognize this problem and know how to fix it.
