The NSS Labs' Q2 report of this year is in, and the findings show that Windows Internet Explorer 9 completely dominates all other browsers when it comes to preventing socially engineered malware.
"NSS Labs performed the first test of web browser protection against socially-engineered malware targeting European users. The socially engineered malware in the report came from instant messages, spam emails and dodgy social network posts; the malware was also targeted at European users, as Eurostat mentioned that nearly 33% of EU users were victims of malware infections in 2010."
"For those that aren't aware, socially engineered malware is a form of malicious software that attempts to trick users into installing it. Socially Engineered Malware remains the most common security threat facing Internet users today."
According to the report, IE9 is the best at preventing unwanted malicious software from being installed. Thanks to IE9's SmartScreen URL filtering prevents 92% of it; and up to 100% when you include Application Reputation to filer untrustworthy executables.
IE8 also does well in this arena, blocking 80% of all socially engineered malware. Other browsers, Safari 5, Chrome 10 and Firefox 4 managed to block just 13% of the malware, with Opera 11 performing worst and filtering just 5%.
Safari, Chrome and Firefox all using Google's Safe Browsing URL blacklisting system perfomred same, whereas Opera relies on an AVG-powered service and is the worst in preventing these attacks, as well as the slowest, averaging 48 hours to block a new malicious site versus 13 hours for the other browsers in the test.
