I am using Comodo Firewall with Avast Pro Antivirus.
Avast has Network shield and I was surprised to see that Avast detected LSASS Attacks and there was no alert from Comodo Fireawll.
I dont think that the network shield from Avast prevents prior Comodo, so that this attacks were blocks at first by Avast and thatswhy there wasnt nothing to be blocked from Comodo??!?! This explanation doesnt sound very seriosly for me.
I had earlier Kaspersky Internet Sekuruty and all this was blocked by it.
That I had Avast with ZonaAlarm Firewall and there were no alerts from ZoneAlarm. So it is logic to think that Zonealarm firewall has blocked all this attacks.
Now I have Comodo and not Comodo but Avast (actually there is no firewll) alert me about this.
