Neither of those indicate actual viruses.

CKAN can't fix false positives with antivirus software.

I raised this as a notification so that someone involved with the project can notify Norton of the problem. I see it has happened in the past, and someone was able to fix the problem then.

Unfortunately, Norton's Whitelisting program has been closed, so there's no longer any way for us to register our releases. All that can be done is Norton users to mark the code as trusted themselves, which feeds in to Norton's database. For information on how to do that, if it is still an option they have, you will have to talk to Norton. They aren't listening to us, anymore.
