Microsoft's Internet Explorer Is Malware Security Leader

By CIOinsight  |  Posted 12-23-2010 Print Email
When it comes to malware protection, Microsoft's Internet Explorer 9 beta Web browser come sout on top, a report from NSS Labs finds.

A malware security report by NSS Labs found Windows Internet Explorer 9 beta caught an "exceptional" 99 percent of the live threats, leading the non-IE pack by 80 percent. Mozilla Firefox 3.6 caught 19 percent of the live threats, down 10 percent from the NSS Labs test conducted in the first quarter of 2010. IE9's protection includes SmartScreen URL filtering, which is included in IE8 as well as SmartScreen application reputation, which is new to IE9.

The report noted Apple's Safari 5 browser caught 11 percent of the live threats, with overall protection declining 18 percent from Q1 2010. Google Chrome 6 caught just three percent of the live threats, down 14 percent from the Q1 2010 test and Opera 10 brought up the rear -- the browser caught zero percent of the live threats. The report concluded the browser provides virtually no protection against socially engineered malware.

From an initial list of 8,000 new suspicious sites, 1,209 potentially malicious URLs were prescreened for inclusion in the test and were available at the time of entry into the test. These were successfully accessed by the browsers in at least one run. On average, 124 new URLs were added to the test set per day. NSS Labs then assessed the browsers' ability to block malicious URLs as quickly as they found them on the Internet, and continued testing them every six hours to determine how long it took a vendor to add protection.
