From Symantec Protection Engine 7.5.3 onwards, you can configure Symantec Protection Engine to handle the file based on its type. It blocks access to any top-level file that matches the file type. If a container file or email message contains a file or attachment that matches the file type, access to the entire container or message is blocked.
