No I'm speaking to everyone - that if you have a firewall problem, then it is good idea to say what firewalls will be running when the problem is evident, and Windows firewall is one sometimes people forget about.
If you only have one firewall running and you still have a problem, then fine - can troubleshoot.
but if you have more than one, then best say so, and save us having to ask.
As I said before I have OA premium firewall and AIS suite firewall running at the same time on one computer and I haven't had any worries. Not my ideal, which is avast Pro with OA firewall. Also I have had third party firewall, and forgotten about Windows firewall being on, and no noticeable conflict between the two.
But is very common for system to exhibit erratic behavior when two firewalls are running at the same time.
ndis filter driver doesn't seem associated with avast products - I think bitdefender and jwire
