What Antivirus solutions for Server 2008 R2 and SBS2008 are availble from Microsoft? - not 3rd party. I have heard of Forefront.

Microsoft has apparently made several changes to the Forefront roadway that has made it very confusing for me

I am currently using "Microsoft Security Essentials" on my Server 2008 R2. Yes! I know it not supported. I want to remove it and use a recommended product. I used to use Panda's enterprise server protection but I no longer want to use that product.

I am familiar with the Microsoft Forefront for Exchange and SBS server. there are so many options such as using Microsoft as the gateway instead of running the application from the Exchange server. I don't know enough to make a choice

However, for a standalone Server 2008 R2, what are my options? Can I use Forefront? what version of Forefront?
