I went to the site using Firefox, but it would only work if I allowed Java
scripting. Then on the test page, Firefox alerted me that it would need to
download the test executable to the disc. I decided to block Java and abort
at that point. Firefox makes it much clearer what you are doing and that
there will be a download if you proceed. FF is safer IF the user makes the
right choice. However, to allow the test in IE, the user has to choose "run",
so the user has the option to block these tests from running (and also the
exploits?). The ultimate result depends on the decision of the user, who is
perhaps the "weakest link."
