A new Trojan horse is redirecting Internet users to pornographic Web sites by exploiting a vulnerability in Microsoft Internet Explorer (IE).

The JS/Seeker-E script can arrive by email or can be embedded into a Web page: when a user opens the email or clicks on the Web page, the script is activated. Once activated, Seeker attempts to change the user's IE settings, such as the start page and search settings, and will redirect the infected user to a porn site. What are some of the better browsers? Does anyone know which web pages?
