Apparently there are more users having the same problem. I'd say ESET does (or should have) by now a pretty clear picture of the problem, it's cause, yet you are asking us to replicate the error again?
That's running around the issue which, circles around creating the dedicated safe HomeNetwork definition setting (when asked after installation) which is not kept by the software, hence the false positives-
/please see the below Log I sent before:
The ESET log shows:
Packet blocked by active defense (IDS) 192.168.x.A 192.168.x.B ARP (A being my router, and B being my machines IP.) The firewall logs keeps scrolling and scrolling and being flooded with this and I believe it is the source of the problem.
