I agree with @SoulAsylum on this situation.
I was successful in restoring my hosts file from a few days ago. Hopefully others can also find a way to restore their file. For those who are reading this for the first time. Do not restart your computer or run a Norton scan until we hear something.
I suspect we might have a lot of users coming as today was Patch Tuesday which does result in a lot of computer restarts.
