CARLSBAD, CA, Aug 13, 2009 (MARKETWIRE via COMTEX) -- NSS Labs, a world leader in independent product analysis and certification, today published its second round of live browser security tests. Two separate tests measured protection against phishing and socially engineered malware across 5 browsers: Apple Safari 4, Google Chrome 2, Mozilla Firefox 3, Opera 10 Beta and Windows Internet Explorer 8.
Socially engineered malware is the most common and impactful threat on the Internet today, with browser protection averaging between 1% and 81%. Internet Explorer 8 caught 81% of the socially engineered malware sites over time, leading other browsers by a 54% margin.
Safari 4 and Firefox 3 caught 21% and 27% respectively, while Chrome 2 blocked 7% and Opera 10 Beta blocked 1%.
Phishing protection over time varied greatly between 2% and 83% among the browsers. Statistically, Internet Explorer 8 at 83% and Firefox 3 at 80% had a two-way tie for first, given the margin of error of 3.6%. Opera 10 Beta, exhibited more extreme variances during testing and averaged 54% protection. Chrome 2 consistently blocked 26% of phishing sites, and Safari 4 offered just 2% overall protection.
Firefox 3.5 crashing issues prevented it from being tested reliably. 
The URLs sample set used in the test was representative of the phishing and socially engineered malware threats Internet users face every day. "In addition of comparing browsers among themselves, the test also benchmarked the browsers against cybercriminals," said Rick Moy, President, NSS Labs. "While the other browsers maintained or decreased protection between the two tests, Internet Explorer continued to improve its protection against cybercriminals."
