Symantec Definition Decoder - from Mike's Tool Set
Back when all the confusion hit in January with the SEP Y2K10 bug...I felt a personal need to know what the JDB file name referenced with regard to definition version. Because of this I wrote a quick utility to decode the file name into the date of the actual set of definitions. I hope someone finds it useful.
Usage: It can be used two ways...the first is you just double click the utility and select the definition package to decode and click open. Because I came from a Macintosh background, I'm also a big fan of Drag and Drop applications, so yes, you can grab a JDB, VDB or XDB and drop one on top of the utility and it will display the decoded version. See screenshot.
