Create lists of file extensions so that you can use them in multiple malware scan
                  configurations. A single list is easier to manage than several identical lists that
                  are each created in a different rule. For example, one list of file extensions can
                  be used by multiple malware scan configurations as files to include in a scan. Another
                  list of file extensions can be used by multiple malware scan configurations as files
                  to exclude from a scan.
To create a file extension list that is similar to an existing one, duplicate the
                  list and then edit it.
You can insert comments into your list by preceding the text with a pound sign ( #
                  ).

View malware scan configurations that use a file extension list
It is useful to see which malware scan configurations use a file extension list to
                  be aware of which rules are affected by any changes you make. For example, you can
                  ensure no scan configurations use a file extension list before deleting it.
Procedure
- Click .
- Select the list and click Properties.
- Click the Assigned To tab.
