+    A mandatory COM class registry entry returned by 'Get-ComClassFromRegistry'.

+    .PARAMETER CheckedPaths
+    An optional synchronized array list. This list is populated each time a filesystem path is analyzed and is found to not be vulnerable. This helps reduce the overall time it takes to check a large number of paths by avoiding to inspect them multiple times.
