We have an issue on a Windows Server 2019 Datacenter virtual machine with Windows Defender.
We are in: Settings -> Update & Security -> Windows Security -> Virus & threat protection -> Virus & threat protection settings -> Manage settings
When Real-time protection is turned on, after about 20-30 minutes it creates hundreds/thousands of files in this location:
C:\ProgramData\Microsoft\Windows Defender\Scans\History\Store
Most of these files are either 1kb or 2kb. Over a 24 hour period we ended up with roughly 950,000 files and it was taking 30 GB of space. This does not appear to be normal. There is no threats detected and no actively running scan or updates. These files appear to be encrypted, or at least we can't open them in notepad and see any useful data. This is only happening on one server.
Anybody got any ideas?
