The US Centers for Disease Control (CDC) in Atlanta, Georgia announced Monday that a letter returned from Malaysia to a Microsoft licensing division office in Reno, Nevada has tested negative for anthrax spores.

A preliminary test came back positive; a secondary test came back negative; a tertiary test came back positive again, and a quartern test by the mighty CDC came back negative again.

Take your pick. Just keep in mind that CDC's medical magicians claim to be the world's best. ®
