Avast One: diarize.exe v0.6 triggers virus quarantine

[Hotziplotzi]

Hi,
I use noScribe 0.5 without any issues. No when I installed v0.6 my Avast One virus scanner ringed the alarm and quarantined the "diarize.exe" file.

This was confirmed via Virustotal.

I don't mind items like "Bkav pro" with their generic AI driven detection as these often raise false alarms, but Avast so far is pretty spot on.

The noscribe.exe also has some issues, but I am less worried here:

Maybe someone can verify what is going on?

My question is also, how one can extract the files from the installer files on windows. This ".nsisbin" thing does not help checking its contents. I had to install everything in a VM to grab the diarize.exe file.

Google "Win64:malware-gen". It's a generic, heuristic-based malware detection by Avast, not a confirmed virus. You will find reports that even official Windows update files have been flagged by this heuristic.

To build the installer, we use the "Nullsoft Scriptable Install System" NSIS: https://nsis.sourceforge.io/Main_Page
However, the original version is limited to filesizes < 2GB. So, we use this extended version: https://sourceforge.net/projects/nsisbi/
I'm not sure if there is any third party tool that can extract files from NSIS archives. 7zip once supported it, but this was removed a long time ago: https://sourceforge.net/p/sevenzip/discussion/45797/thread/5d10a376/ You can try to find an old version of 7zip.

Thanks for the quick reply. I suspected a false positive and have reported the file to Avast. Now I hope they fix it quick.
With regards to getting to extract the nsisbin contents: I tried old 7zips (according to the discussion any version <15.06 should work) and sadly they do not work.
