Automatic scans - Depending what software you choose, you may be able to configure it to automatically scan specific files or directories and prompt you at set intervals to perform complete scans.

Authoring Workflows A new XML -based language XAML is commonly used for declaring the structure of a workflow. However, the workflow may also be expressed in code using any .NET-targeted language ( VB.NET , C# , C++/CLI , etc.). Workflows comprise 'activities'. Developers can write their own domain-specific activities and then use them in workflows. WF also provides a set of general-purpose 'activities' that cover several control flow constructs.
