How do I get rid of the unsafe website warning in Samsung's default browser?

[Rikku Watro]

It gets so annoying as sometimes using a restaurant's free wifi causes everything to be blocked by this red screen with a warning sign saying "You should not proceed, especially if you haven't seen this warning before." I saw an option saying "Proceed anyway," but I sometimes get this when I use free wifi or visit certain sites that are safe and real.
