NSS finds Internet Explorer and Google Chrome to block most malware, Apple Safari, Firefox, and Opera did not.

Research by NSS Labs indicates that in its testing, Microsoft (MSFT -0.04%) Internet Explorer and Google (GOOGL -1.02%) Chrome are the safest browsers.

NSS, which bills itself as "the world's leading information security research and advisory company," recenlty unveiled the results of its Browser Security Comparative Analysis: Socially Engineered Malware. Over the course of 28 days, from March 13 through April 9, the firm tested the five, most popular browsers against 754 samples of real-world malicious software. The browsers were Apple (AAPL -1.96%) Safari 5, Google Chrome 25/26, Microsoft Internet Explorer 10, Mozilla Firefox 19, and Opera 12.

The results revealed significant safety differences.

By using a combination of three different safety tools, Internet Explorer and Chrome topped the list. Altogether, IE blocked about 99.6% of  all incoming malware; Chrome blocked 83.16%. Falling a distant third was Apple's Safari. Opera offered essentially no protection with 1.87%. 

NSS says the web browser is both "the primary vector by which malware is introduced to computers" and "the first line of defense against malware infection."
