“ What is the finest antivirus software for SharePoint? ” is an inquiry that we are bumped into several times. For my part, I would answer Microsoft Forefront Security for SharePoint.

A year back when I posted some articles on this technology, including Microsoft Forefront Security for SharePoint, Installing Microsoft Forefront Security for SharePoint, SharePoint Keyword Filtering in Forefront, SharePoint File Filtering in Forefront, and Keyword Filter Installer in Forefront for SharePoint. And other than the request of some colleagues, I am posting this demonstration video to provide an easy-to-follow implementation steps:

However, if we are using other file-level antivirus program, Microsoft Help and Support has provided us the list of folders we need to exclude from antivirus scanning to avoid unexpected behaviors:

1. Windows SharePoint Services 3.0

a. Drive:\Program Files\Common Files\Microsoft Shared\Web Service Extensions

b. Drive:\Windows\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files

c. Drive:\Documents and Settings\All Users\Application Data\Microsoft\SharePoint\Config

d. Drive:\Windows\Temp\WebTempDir

e. Drive\Documents and Settings\the account that the search service is running as\Local Settings\Temp\

f. Drive:\WINDOWS\system32\LogFiles

g. Drive:\Documents and Settings\Default User\Local Settings\Temp

2. Microsoft Office SharePoint Server 2007

a. Drive:\Program Files\Microsoft Office Servers\12.0\Data

b. Drive:\Program Files\Microsoft Office Servers\12.0\Logs

c. Drive:\Program Files\Microsoft Office Servers\12.0\Bin

In addition, it is recommended  that we deploy an antivirus solution based on the SharePoint Portal Server Virus Scanning Application Programming Interface. And to learn more on how Forefront Security for SharePoint can help protect Microsoft Office SharePoint Server 2007 and Microsoft Windows SharePoint Services 3.0, you can view its online product demonstration.

Thanks.
