Internet Explorer 9 utterly dominates malware-blocking stats
Internet Explorer 9's dual-pronged approach to blocking access to malicious URLs—SmartScreen Filter to block bad URLs, and Application Reputation to detect untrustworthy executables—provides the best socially engineered malware blocking of any stable browser version, according to NSS Labs' latest report.
Internet Explorer 9 blocked 92 percent of malware with its URL-based filtering, and 100 percent with Application-based filtering enabled. Internet Explorer 8, in second place, blocked 90 percent of malware. Tied for third place were Safari 5, Chrome 10, and Firefox 4, each blocking just 13 percent. Bringing up the rear was Opera 11, blocking just 5 percent of malware.
The study only looked at sites that depended on tricking users into installing malicious software; anything that used browser flaws to run wasn't included in the test. The focus was also exclusively on malware targeting European users, though Internet Explorer 9 has also scored highly in other tests by the company with a global purview. The URLs visited were harvested from spam e-mails, instant messages, and social network posts.
