symantec endpoint protection complaining

+1 vote
This has been mentioned a few versions earlier I think, but both 1.0.5 and 1.0.6 are being flagged by my company's symantec endpoint protection software. SEP doesn't shut up about, making it impossible to work with these versions

There's a limit to how much we can do about this. MultiChain can't run without opening certain ports on your computer, and its traffic will inevitably look somewhat like bitcoin's, since MultiChain extends the bitcoin protocol. However it would be helpful if you could provide information on exactly what is being reported when the software is being flagged, e.g. is it the binary executable, the ports it's opening, its communications protocol, etc?

OK, thanks. The problem appears to be that Symantec is detecting some similarity between MultiChain and Bitcoin Core, which is true because MultiChain began as a fork of Bitcoin Core. We have no easy solution to this without rewriting a large part of the MultiChain code base, so I would recommend talking to your system administrator to understand if an exception can be put in place.
