CSHARP123 writes "In a move that's sure to raise some eyebrows, Microsoft today debuted a new web site designed to raise awareness of security issues in web browsers. When you visit the site, called Your Browser Matters, it allows you to see a score for the browser you're using. Only IE, Chrome, or Firefox are included — other browsers are excluded. Not surprisingly, Microsoft's latest release, Internet Explorer 9, gets a perfect 4 out of 4. Chrome or Firefox do not even come close to the score of 4. Even though the web site makes it easy for users to upgrade to the latest version of their choice of browser, Roger Capriotti hopes people will choose IE9, as it blocks more malware compared to Chrome or Firefox." Of note in the Windows Team post is that the latest Microsoft Security Intelligence Report discovered that 0-day exploits account for a mere tenth of a percent of all intrusions. Holes in outdated software and social engineering account for the majority of successful attacks.
