Another report of a missed detection on the malwarebytes forum http://forums.malwarebytes.org/index.php?showtopic=39902

the malicious URL in question is http://www.chinchadenoche.com/cgl-bin/cholin/dedicacion.exe

With all detections in NIS2010, you first get an very informative Norton Insight dialog.

Most users will choose not to run the malware. But even if they do, the second proactive layered protection component kicks it SONAR and kills the threat. Once again, just a reminder, there are NO SIGNATURES AT PLAY here. All of this detection is zero day.
