There's a bug in Internet Explorer that allows attackers to execute malicious code on your machine under certain conditions. When Microsoft first acknowledged the vulnerability a few days ago the company was under the impression that only Internet Explorer 7 was affected. But the security advisory has been updated and it's now clear that the flaw affects every version of Internet Explorer from IE 5.01 SP 4 through Internet Explorer 8 Beta 2.

Microsoft recommends enabling a firewall and anti-virus software to minimize your risk, as well as using Protected Mode in IE7 or IE8. We'd add that you could also switch to a browser that doesn't have this vulnerability like Firefox, Google Chrome, Safari, or Opera at least until Microsoft issues a fix.
