I got the nightly release for March 7th 2018
When I extracted the archive to a folder in my desktop Windows defender warned me that it detected the file at Kolibri\HD_Load\9x2klbr\9x2klbr.exe as "Trojan:Win32/Azden.A!cl" I assume this is a false alarm, but I figured it might be good to tell somebody about it.
If you downloaded the nightly release from the official site, then there are no Trojans. It is a false alarm.
Sources are open. You can check them by yourself.
P.S. KolibriOS developers do not write Trojans. They just is not profitable to do so.
The Glass is Always Half Full!
