Please make sure you have checked in the latest VirusScan Enterprise for Linux Reports extension - this should then give you a section in the query builder labelled "LSH Properties" : in this section there should be an item called "DAT Version (LSH)", which I think is what you need.
;-) I've already try this field, but no result.. My VirusScan Enterprise for Linux Reports extension are too old, I update theses extensions and give you some news.
Thanks for your help !!
It's ok, we have some new fields for Linuxshield now.
Thank you JoeBidgood !
