Before I started using Firefox, my default browser was Internet Explorer. That was the start of my problems with "404 Not Found nginx". I can no longer access Google. That was when I converted to using Firefox, in hopes that this problem would go away. It didn't. Again if I typed in "www.google.com" in the URL box, the nearly blank page with "404 Not Found nginx" would show up. I decided to just stick with Firefox but just use "Bing" as my default search engine. Only about a week later the same problem occurred with Bing. I then tried Yahoo, but there was no luck with that either. I currently do not have a search engine to use. Please help.
