Procedure:

1. In DV Converter, open the .rules file that you intend to convert by selecting File > Open > Snort Rules from the menu and browsing to the file.
2. Review the "Status Indicators" for the rules in the file that are displayed to determine if any rules are invalid and which ones you want to modify.
3. If any rules are invalid, edit the rule attribute values until they validate successfully. You can also delete any rules that you do not want in the conversion file.
4. When all rules that you want to convert have been validated, save the conversion to a file by following these steps:
   1. In the menu, choose File > Save > Digital Vaccine XML, or select the Save icon on the toolbar.
   2. Navigate to the location where you want to save the file and name the file with a meaningful name that properly identifies the rule set.
   3. Click Save. DV Converter saves the file in XML format (by default the .xml file extension is selected). 
5. After saving the conversion file, you can import it into DV Toolkit to include in DVT filter packages.
