My personal favorite approach is sandboxing; separating a running Windows application from the rest of the system. Sandboxing works with all web browsers, in addition to email programs and any other Windows application. Whenever I visit a website that I am the least bit suspicious of, I do so in a sandboxed web browser. This offers protection from all sorts of security issues, not just Java. For sandboxing, I highly recommend Sandboxie. I have used it a long time with no gripes at all and I can gripe about anything.
