[MOD: For reports with 3.4 see https://getmusicbee.com/forum/index.php?topic=18398.msg181888#msg181888]


Both Chrome and MS Defender returned a trojan warning when downloading the latest MB zip file (final release candidate). I'm sure it's a false positive, but it wasn't a problem for previous releases.

Here's MS relevant webpage: https://www.microsoft.com/security/portal/threat/encyclopedia/entry.aspx?name=Trojan%3aWin32%2fFethar.B!cl&threatid=-2147258321&enterprise=0

I have the same issue. Windows Defender was very aggressive about it. I assume it's nothing, but I'll hold off on upgrading for now.

Assuming you're downloading from the MusicBee website, it's a false positive.  You can run it through Virus Total to confirm: https://www.virustotal.com/en/
Download the latest MusicBee v3.5 patch from here.
Unzip into your MusicBee directory and overwrite existing files.

i dont know what to make of this. The last release candidate was also reported by one or two people and then the issue disappeared after that (i assume with a later windows defender definition file). The thing is I use windows defender myself and never had issues (just ran a Scan Now to reconfirm). Also downloaded on another windows 10 machine/ windows defender and no issues reported.

Trying with VirusTotal, there is 1 out of 56 reporting a virus
Rising    Malware.Undefined!8.C-zFh4eF8usxI (Cloud)    20160508
but microsoft is not one of them

On mine personally, I'm getting a "Trojan:Win32/Fethar.B!cl" notification. Which is very odd indeed. I'll just try updating definitions again later and see if that fixes it.

EDIT: It seems being even one definition update behind seems to cause that false positive, at least on Windows Defender. Doesn't pop up again after it is updated, thankfully.

I just updated definitions before downloading again and I still get the report of "Trojan:Win32/Fethar.B!cl" being found.

Just updated to "Definition Update for Windows Defender - KB2267602 (Definition 1.219.1201.0)" and tried again: no virus warning this time although I got the "Windows Smartscreen" warning, but this one's been showing up for a while.

I don't think there's much to be concerned about. Probably this is happening as RC files include a self-extracting zip file. If not Windows Defender then a few other AV programs would always report it as malware. Don't bother with RC files. Only for the official release file, report to AV apps if they throw a false positive.

i believe SmartScreen is based on some sort of reputation rating. Because its a new .exe and because its an unknown publisher then it has no reputation.
To become a recognised publisher i would need to purchase a microsoft approved certificate each year.
So when i do the final release that too will be a new .exe and will take a while before a reputation is established.
The strange thing is on my windows 10 machine which is not the machine used for developement, i downloaded and installed the file without this happening (or any of the AV warnings)

That's strange as I'm using Win 10. Oh well, no big deal. I'm not concerned about it since it's a beta version and I browse the forum regularly but it might generate some trust issues for new users.

Did you run the exe through Virus Total?  You'll find that at most one or two out of 50+ will come back with a false positive.  No one is forcing you to use MB, but trust us - if you downloaded it from the MB website, the problem is with your AV definitions and not with MB.
Download the latest MusicBee v3.5 patch from here.

Don't you think if there was malware or a virus in the exe that out of the thousands (tens of thousands?) of MB users there would be more than two or three complaints?
Oh yee of little faith.
