Internet Explorer got a black eye last week from a widely exploited zero-day vulnerability, but a recent NSS report shows that IE 9 does a better job of blocking malware than the other major browsers. It looks like the key to Microsoft’s success is their SmartScreen technology, which basically maintains a blacklist of bad URLs.
This flies in the face of conventional wisdom right now, which states that Chrome is the most secure browser. I don’t think that I will switch from Chrome on my Mac to IE 9 on a VM yet. But I will feel more comfortable using IE 9 or 10 to browse while I am running a Windows environment.
