The Malware Protection Center (MMPC) Portal V2 Beta is a preview of the next version, which contains a subset of the final V2 features. These features include stream-lined sample submission; which is made possible by creating an MMPC profile.  When logged in, the information saved in the MMPC profile auto-populates the sample submission form, expediting the sample submission process. Another improvement to sample submission, and perhaps the most exciting new feature, is the ability to track submission status on-line.  The user can now track the status of any/all sample submissions made while logged in to the portal.\, announced Monilee Atkinson.
