From Kevin Remde’s blog:

We’re releasing early select customer betas of both Microsoft Client Protection and Microsoft Antigen for Exchange.  Microsoft Client Protection is business-class antispyware, anti virus, and attack protection, with an integrated management console that provides centralized management and reporting.  The Antigen suite are the Sybari products we acquired when we purchased Sybari last year.  Now we are coming out with updated, Microsoft-Branded versions of the Antigen for Exchange, Antigen for SMTP Gateways, Antigen Spam Manager, and Antigen Enterprise Manager, and we’re making betas of these available to select customers.

</end> I personally cannot wait for Microsoft to get things going in this space. I have yet to use a product that handles anti-virus, firewall and anti-spy well on the Microsoft platform from a third party. They either render my system useless (ZoneAlarm) or give me things I don't want. I have had nothing but a fine, smooth experience with Microsoft OneCare and if the MCP for the enterprise can deliver in a similar way, sign me up today!
