I'm using this one on SEP 11.

I'd just finished updating this for the 3rd time a few days ago and am posting it for the 3rd party EA for SEP. It's ugly, but it works for us. We're likely moving to McAfee soon, so I'll get to start all over again.

EDIT: Noticed an issue with some of our machines running SEPv12 and the number of older def folders kept. This should now just query the 'engine.mfst' file for date info and should be absolute.
