-// Open or run a downloaded file via the Windows shell, possibly showing first
-// a consent dialog if the the file is deemed dangerous. This function is an
-// enhancement over the OpenItemViaShell() function of win_util.h.
-//
-// The user consent dialog will be shown or not according to the windows
-// execution policy defined in the registry which can be overridden per user.
-// The mechanics of the policy are explained in the Microsoft Knowledge base
-// number 883260: http://support.microsoft.com/kb/883260
-//
-// The 'hwnd' is the handle to the parent window. In case a dialog is displayed
-// the parent window will be disabled since the dialog is meant to be modal.
-// The 'window_title' is the text displayed on the title bar of the dialog. If
-// you pass an empty string the dialog will have a generic 'windows security'
-// name on the title bar.
-//
-// You must provide a valid 'full_path' to the file to be opened and a well
-// formed url in 'source_url'. The url should identify the source of the file
-// but does not have to be network-reachable. If the url is malformed a
-// dialog will be shown telling the user that the file will be blocked.
-//
-// In the event that there is no default application registered for the file
-// specified by 'full_path' it ask the user, via the Windows "Open With"
-// dialog.
-// Returns 'true' on successful open, 'false' otherwise.

-// Invokes IAttachmentExecute::Save to validate the downloaded file. The call
-// may scan the file for viruses and if necessary, annotate it with evidence. As
-// a result of the validation, the file may be deleted.  See:
-// http://msdn.microsoft.com/en-us/bb776299
-//
-// If Attachment Execution Services is unavailable, then this function will
-// attempt to manually annotate the file with security zone information. A
-// failure code will be returned in this case even if the file is sucessfully
-// annotated.
-//
-// IAE::Save() will delete the file if it was found to be blocked by local
-// security policy or if it was found to be infected. The call may also delete
-// the file due to other failures (http://crbug.com/153212). A failure code will
-// be returned in these cases.
-//
-// Typical return values:
-//   S_OK   : The file was okay. If any viruses were found, they were cleaned.
-//   E_FAIL : Virus infected.
-//   INET_E_SECURITY_PROBLEM : The file was blocked due to security policy.
-//
-// Any other return value indicates an unexpected error during the scan.
-//
-// |full_path| : is the path to the downloaded file. This should be the final
-//               path of the download.
-// |source_url|: the source URL for the download.
