Antimalware Service Executable - Windows Defender Service - Large Network Usage
Antimalware Service / Windows Defender Service is using a large amount of network resources quite often on my machine. I am trying to first pinpoint WHY this is happening, before I move forward with a few ways to curb it from happening.
Screenshot:

My hunch is that I have Crashplan running on my PC, which is looking at a network drive and locally transfering data from NAS to Desktop PC, where it sends to the Crashplan cloud for backup - and Windows Defender sees it as new data so it's trying to scan it every time.
In any case, I also don't want to stop Windows Defender from scanning what it should in real time, I just don't want it to do it if it's from an internal network resource headed to crashplan (if this is the culprit) which has undoubtedly already been scanned.
So to be clear, I am looking for ways to pinpoint why it does this and then stop it from happening IF that is desired. I want Defender to do what it does to help protect the PC, but not at the cost of high resource usage even on my internal network only.
My reference for possibly disabling if desired in the future: Disabling Microsoft Antimalware service

I have sample submission off and I am still seeing a high network usage. However, I notice it is "receiving" a lot not sending a lot.
