Second:
Populate your file with the URLS you want to splice.
it would be REALLY SLICK if someone were to develop a web gui for it, kinda like ntopng where you install clamav and then navigate to a web address:port-number and have a dedicated page for all things clamav..
I doubt there's even a way to request that, along with the considerable resources it would take to develop it.
