MSFT Defender Win32/Varpes.L!plock in SABnzbd-1.0.0RC1-win32

MSFT Defender on my Win10 system just tagged SABnzbd-1.0.0RC1-win32-setup.exe as infected with Win32/Varpes.L!plock.
This must be a new def for the detection, as the file has been on my disk for a while, and now is the first time Defender complained.

Anybody else experience anything like this?
I hope it is a FP?

Very likely a false positive.
Two out of 54 and both reporting different viruses.
I'll check. In the past we've had an FP due to a compressed SQLite library.
Maybe we forgot to uncompress it on the latest VMWare build image.
