NSS Labs has published three independent studies on web browser protection against socially-engineered malware. The tests were performed during first quarter of 2009, 3rd quarter of 2009 and the first quarter of 2010.
In all three tests, Internet Explorer 8 was the only browser that improved its block rate test-over-test, successfully stopping 69%, 81%, and 85%. This shows Microsoft’s continuous commitment to strengthen security of our browsing platform against emerging threats.
As per this independent report, as of today (Q1 2010), Microsoft Windows Internet Explorer 8 is most secure browser that can protect you against socially engineered malware.
