IE gains ground in browser security battle

There’s no one answer to the question of which web browser is the most secure, but most IT pros wouldn’t expect any of Microsoft’s offerings to be in contention. 

Internet Explorer 9, which is only in beta release, was rated the best browser at blocking downloads of malware, according to a recent study by NSS labs. IE9 blocked 99% of malware and was five times more effective than the second-place browser, Mozilla’s Firefox.

The study was commissioned by Microsoft, so take the results with a grain of salt. However, there is solid reason to believe IE9’s security is significantly improved over its predecessors’, thanks to the addition of a new Application Reputation (or App Rep) feature.

App Rep uses an algorithm to analyze a file’s contents and reputation to determine the probability that the file is malware, and warns users accordingly.

IE9’s beta can downloaded here.
