Microsoft's Internet Explorer 9 is most effective web browser for blocking malicious websites and downloads, a report claims.
NSS conducted the study at the behest of Microsoft, who were keen to know how effective its browsers' anti-malware protection systems were. It was found that IE9 is 9 per cent more secure than Internet Explorer 8.
Microsoft credited the enhanced security on IE9 to its new SmartScreen Application Reputation, which uses a sophisticated set of algorithms to determine whether a downloading file is legitimate or not.
Jeb Haber, the head of IE's security team, said in an interview: “We wanted to look at malware blocking from a new perspective. We looked at what people are downloading [via IE] and found that a significant percentage of executable files were later confirmed to be malware.”
