Microsoft Builds Own Antivirus Engine

While customers may have to wait until next year for the Client Protection tool, Microsoft on Thursday also announced the availability of Antigen, an antivirus program for messaging and collaboration servers that it acquired with the purchase of Sybari Software earlier this year.

Antigen will soon be bolstered by Microsoft's own antivirus scan engine, the company said, which all customers will receive as a free upgrade. In addition, a beta of Antigen specifically designed for Microsoft Exchange will ship early next year. According to Microsoft, the program "has been shown to achieve measurably improved levels of security."
