During normal computer usage I never see this, but when I run Vuze (aka Azureus), I'll see it pop up a few times. I have no problem seeing it, I'm happy that MB has protected me and would have it no other way, you guys rock.
My question is what has actually happened to cause this popup. I suspect it's either that you've actively detected some malware intrusion attempt and stopped it happening before it could do any damage, or what I think is more likely ... you've detected my machine has a network dialog to an IP address or Domain that you've got on a blacklist due to research or reports of it having been infected.
The latter option meaning that before any malware even would get the chance to try something, if the remote machine is still infected, you've blocked it before it got a chance.
If these particular blocks are solely from a blacklist, does that mean that malware bytes can't actively detect attempts at intrusion and it's only ever working to block traffic from a blacklist? Or are there other MB modules/processes that are actively monitoring attempts to install software, overwrite DLL's, inject things into the startup sequence, etc?
