title: .NET virus scanning API
body: <p>I'm building a web application in which I need to scan the user-uploaded files for viruses.</p>
  
  <p>Does anyone with experience in building something like this can provide information on how to get this up and running? I'm guessing antivirus software packages have APIs to access their functionality programatically, but it seems it's not easy to get a hand on the details.</p>
  
  <p>FYI, the application is written in C#.</p>
