The full VB comparative is only available to subscribers for now, but here's the result chart from the "RAP" (Reactive and Proactive) test:

For those who are not familiar with the VB methodology, RAP test consist of a "reactive" portion where samples collected during the 3 weeks prior to the date of the AV signature/definition file were used, and a "proactive" portion where samples collected during a week after the date of the AV signature/definition file were used.

As always, note that this comparative only test one aspect of the AV software. Many AV products now include modules that can identify/stop malware that are not detected by their signature-based detection engine.

This makes me glad I use ESET when I'm on Windows. Linux is still ftw tho.
