This check is a variation on an existing check for Symantec Endpoint Protection Anti-Virus definitions. (https://exchange.icinga.com/exchange/check_symantec_av). I rewrite this check so you can use it as a local check for check_mk. Tested with SEP Version 12.x.
Installation: Copy the script to your local check_mk folder. (e.g. C:\Program Files (x86)\check_mk\local).
