Thanks Slayer for the update on the Safari security issue. I wonder if it's only a Win 7 issue or if it also relates to OS X. I should digg further.

In the same way the only way to guarantee you'll never have a car accident is to close yourself into your house, never go out, build a strong encircling wall around your property so nobody can crash in. And voilĂ .
