I am getting this warning when kodi is searching for providers. Any idea if this is a false positive?

Ill take a guess that the "black list"  contains a list of nefarious sites that should be blocked..AVG has recognised some or all of the sites contained in the list  as "bad"  and has blocked it being downloaded...in this case I'd say its a false positive..as the file trying to be downloaded is meant to protect Kodi from visiting those sites.

AVG - you get what you paid for!
