A few days ago I noticed several new network connections on the firewall, all showing up as Unknown:#### (ex: Unknown:3852). The connection is listening on my computer (showing a red arrow and .) and the IP address is 127.0.0.1, which I understand is a loopback address (though I only have a cloudy idea of what that means). However whenever I try to trace it it traces to www.007guard.com, a malware domain. But then again, several of my legitimate programs and connections trace here too, and I have no idea what to make of it. Both the boot-time scan and regular scan have found nothing. I’m wondering if there’s a way to manually block a connection (I haven’t found one) or what exactly it is if it’s not dangerous.
(I’m running Avast Internet Security 6.0.1091)
