Hi Boris,
Thanks for the heads-up, and for suggesting the hash check.
Microsoft has reviewed the files and removed the detection, so the 7.9.0.0 installers and the Host should no longer be blocked.
If Defender still flags them on a machine, it is probably running older definitions. Update them in Windows Security > Virus & threat protection > Protection updates, then try again.
Let us know if you still see a block.
