There are two primary ways that drive-by downloads are done, either through a vulnerability in IE itself or an add-on, or because the user has the security setting set too low.

The target audience is technology enthusiasts. But it can be broadly used. We feel very good about it.

We'll support Beta 2 with security updates, either as a patch [via Windows Update] or as a new release.

I'd recommend that users running IE at home especially give Beta 2 a try. Its security benefits outweigh any risks of using beta software.

We'll continue to do performance tuning and bug fixes, and improve the reliability through the beta process.

IE 7 Beta 2 Preview is feature complete. It's a developer and technology enthusiast preview release. Up until now, we've been documenting the rendering and technical changes to IE 7, but people haven't had a way to test it against their sites unless they were in the beta program. IE 7 Beta 2 Preview is a safe release for early adopters, or anyone who has a business need to understand where we're going with IE.
