Windows Internet Explorer 9 (IE9), Google Chrome 12, Mozilla Firefox 4, Apple Safari 5 and Opera 11 were tested with 1,188 malicious URLs - links that lead to a download that delivers a malicious payload or to a website hosting malware links.
Each of those browsers uses a variety of security technologies that protect users from this type of attack. All of them use a reputation-based system that works by comparing URLs with a blacklist or whitelist located in the cloud that gets updated manually and/or automatically. If the URL is found to be malicious, the browsers redirect the user to a warning page.
The results for IE 9 were almost perfect: the browser blocked 96 percent of the suspicious URLs when its URL reputation filter was enabled, and an additional 3,2 percent after its Application reputation filter was enabled. http://www.net-security.org/malware_news.php?id=1803
