I'm trying to ensure protection through your product in the following instance.

We have company webservers(IIS) running your corperate product version 6. I'd like to add a .NET web-page that allows file uploads using class/object System.Web.UI.WebControls.FileUpload

If we have your product scanning on the HttpRequestContent do we need additional virus scanning on the individual file once the request is received or can I consider it clean at that point? If so, how do I handle the flagged httprequest?

Additionaly, is there a .NET plugin or API call to programmatically scan each and every file they want to upload before we write it to our web-servers disk?
