Windows Defender Blocking Sonarr as Trojan

[Messydesk]

Sonarr version Newest Master downloaded today:
Mono version (if Sonarr is not running on Windows):
OS: Windows 10 Creators Update
Debug logs:
(Make sure debug logging is enabled in settings and post the full log to hastebin/pastebin/dropbox/google drive or something similar, do not post them directly here)
Description of issue:
So I’ve been running Sonarr fine for ages and today Windows Defender told me that it had removed Sonarr because it contained trojan “Rundas.B”. I tired to re-install from the download link on the main site and everytime I tried to DL the master.exe it told me that it had a virus and wouldn’t download it.

I turned off Windows Defender and pushed the DL through and installed, Sonarr installed an ran fine, but then when Windows Defender turned itself on automatically, it removed Sonarr again and gave me the following info.

Any ideas?

It’s a false positive and something they will need to address, it’d be best to submit it to MS:

If you can exclude that file and tell Defender to ignore it, that is a workaround.

Will do! Thanks for the amazing product/support/good times. Appreciate it.

I’d love to know what caused Windows Defender to suddenly classify it as a threat, since this master release is over a month old.

Btw. VirusTotal analysis:

Installer

Main Executable

So check the hashes to see if you have the same ones.

Great! I’ll check those when I get back home tomorrow.
Thanks for posting those.

Thanks for that. Everything looks to a match for the hashes.
