If you're looking to snag the initial beta version of Microsoft Security Essentials from the source, here are a few things to be aware of:

  • US, Israel, and Brazil only (China in 30 days)
  • Public downloads will be capped at 75,000
  • Download will be made available around 9 am PDT/12 pm EDT
  • Requires Windows XP (32-bit only), Windows Vista or Windows 7

For more info, please check out my overview of the public beta.

Please, no emails or posts about the torrent versions. Obviously, it's out there. Obviously, downloading a security product via torrent is ... well, dumb.
