They're sharing the infected files (malicious code) not the definitions.
The malicious code copyright is difficult to defend...
If you want to disagree, do it reasonably.
unless the participants found a way to scan files without using the original AV software technologies, and centralize the results in DACS, a Comodo labeled product right?
Sounds like Comodo may have acquired Immunet?

(I don't care if there are differences or not, it's the same concept)
is that more reasonable?
End user has AV xx installed on his system and wishes to participate in DACS for the good of the community. They will install a plugin that allows communication with DACS (through EasyVPN).
Now when a Comodo user scans a file that is unknown, DACS will send this file to the participants with various AV's installed. Those AV's will scan the file, and the result is sent back to DACS. DACS in turn will gather results from all of the supported AV's.
... now it would get funny if all participants were using Comodo AV

... which is very likely to happen. I mean for instance would you expect me as an Avast user to participate in a Comodo program? for the safety of mankind may be? no freakin' way

get a life Comodo
