Very weird, this is the TBB direct from Tor.
Trojan:Win32/Malgent!MTB
…Tor Browser\Browser\TorBrowser\Tor\tor.exe
And it links to : https://www.microsoft.com/en-us/wdsi/threats/malware-encyclopedia-description?name=Trojan%3AWin32%2FMalgent!MTB&threatid=2147836816
Anyone else having issues with TBB?
too easy for Microsoft or third-parties to collect telemetry data would be my guess
