IE 9 Offers Best Social Site Security
Internet Explorer beat all other browsers hands down when it cames to preventing socially engineered malware, according to NSS Labs latest report.
Socially engineered malware is a form of malware that tricks users into installing it from the social sites.
Thanks to Internet Explorer 9’s SmartScreen URL filtering the browser prevents 92% of it; and up to 100% when you include “Application Reputation” to filter untrustworthy exe’s.

IE 8 also does well blocking 80% of all socially engineered malware.
Other browsers look just pitiful in comparison: Safari 5, Chrome 10 and Firefox 4 (the latest browsers at the start of Q2 2011) managed to block just 13% of the malware, with Opera 11 performing even worse and filtering just 5%.
While the report does reveal Internet Explorer 9 is the best at preventing unwanted malicious software from being installed, it comes at the cost of a higher-than-average false positive detection rate.
