why does this hybrid analysis "detects" two viruses in the installer?
The hybrid analysis here https://www.hybrid-analysis.com/sample/19749847da2a7145770c71910a90e870724d39b2bdb4efbb7bedd917f7a05926?environmentId=100
says that the installer contains "The analysis extracted a file that was identified as malicious details 1/10 Antivirus vendors marked dropped file "plugin-container.exe" as malicious (classified as "Trojan.Heur" with 10% detection rate) 1/10 Antivirus vendors marked dropped file "System.dll" as malicious (classified as "Adware.Domage.Neobar.BF" with 10% detection rate)"
I really don't trust the results of that site but I am wondering why it says that. Other languages installers and they have different results.

Did you get the full installer from Download Firefox For All languages And Systems {web link}
I don't think plugin-container.exe is malicious. When I cross-check its sha256 hash over here:
It has one "Heur[istic]" detection and 36 clean.
System.dll is associated with "maintenanceservice_installer.exe". When I cross-check its sha256 hash over here:
It has 1 "Adware" detection and 36 clean.
I'm not worried enough to look into it further.

Yes, I actually put the link in the upload file section.

I know, and I really wonder why they say that about firefox which is free and safe.
Is Hybrid analysis a Mozilla program? If the installer is from the Mozilla site I would be wary of other tester software saying something that isn't there as well giving you a false positive and it by itself could be the culprit as well.
