Queries to Webroots servers

I was just thinking to myself that the amount of events that are shown on picture below is a lot, how many of these events are actually queried to Webroot's servers? Just file events and network/internet events? Or all of them? If so seems a lot for only a few weeks at already 20 billion events.

 

These are events occurring on your system, and only a very small fraction will ever be sent centrally - most are classified locally.
