So there’s yet another IE vulnerability (which isn’t to say Mozilla or Safari are perfect) so let’s see what Microsoft has to say about avoiding malicious hyperlinks. From Knowledge Base Article 833786:
The most effective step that you can take to help protect yourself from malicious hyperlinks is not to click them. Rather, type the URL of your intended destination in the address bar yourself. By manually typing the URL in the address bar, you can verify the information that Internet Explorer uses to access the destination Web site. To do so, type the URL in the Address bar, and then press ENTER.
