Pretty sure @Timothy_Hall is correct here.
We launched as part of R80.40 and other R80.x via JHF an autoupdater for Threat Extraction, DLP, and Content Awareness.
It is enabled by default in R80.40 and disabled by default in other R80.x with the relevant JHF installed.
It works on a similar principle to IPS today where a new update is automatically downloaded and applied, with the relevant policy install taking place automatically.
You can also revert to an older package if necessary.
