Please send the download URL, because i downloaded many and while installing it tell me that the system is not supported.

Answer: 
[Register with McAfee](https://secure.nai.com/apps/downloads/free_evaluations/survey.asp?type=d&prodid=2796&mktg=ESD345&bu=McAfee&region=us&segment=small&RefreshPartner=UNITED%20STATES), and then download [McAfee ViruScan Enterprise 8.5i](http://www.mcafee.com/us/enterprise/products/system_security/servers/virusscan_enterprise.html). It'll run on all versions of Windows Server 2008, and it's pretty much the same as all the other virus scanners for Windows Server products.
AVG Business Version

This is the professional level version of AVG, not the free edition. You can get the standalone clients or go all out with a dedicated AVG server to manage client installs of AVG.

You can download trials and read more at: <http://www.avg.com/us-en/download>

I have used this one personaly in a corporate environment and it works quite well.
