[Clamav-devel] GPL license question

[Joel Esler (jesler)]

I'm not a lawyer. Nor do I play one on TV.   But I am the community manager, and I have a lawyer that I ask my questions to, so if I really need to go to him.

That being said.

There are a ton of commercial applications that use Clam.  You'd frankly be surprised.  I still am.  It depends on how you link to clamav.  You can use clamav and parse results, things like that.

Where it gets tricky is if you modify code or do internal links to the code.  But you can ship clamav packaged with something else, if you do it right.  That is possible, yes.

Good question Patric. I am also noticing bunch of commercial security tools
for web hosting servers, which are directly or indirectly using ClamAV
libs/binaries so far. I have been wondering same because it shouldn't be
use that  based on the docs!

Hi,

I know clamav is released under GPL license, and third-party commercial
app shouldn't link libclamav.

However I find there is one anti-virus app link libclamav directly and is
published on Mac app store.

This app is
https://itunes.apple.com/us/app/bitmedic-antivirus-malware/
id1001746820?mt=12

Below is otool result of BitMedic binary otool -L BitMedic
BitMedic:

/System/Library/Frameworks/ServiceManagement.framework/Versions/A/ServiceManagement

/System/Library/Frameworks/SystemConfiguration.framework/Versions/A/SystemConfiguration
(compatibility version 1.0.0, current version 699.1.5)



I want to know if this way used by Bitmedic is legal and other developers
can also use clamav directly in their commercial app.
