Bug on Eset's side.

They are misbehaving in some way.

You can confirm that this is the case by installing an AV like Avast 
with full firewall capability turned on (may need to pay, but worth 
while to confirm).

The reason I am confident that it is a bug on the AV side and not D's is 
because I don't remember hearing about this happening before.

It may be possible to add a workaround on our end, but we'll need Eset 
on our side for that I think.

Based upon a quick search on Google, its looking like Eset consider this 
a feature not a bug.
