I am using ZA Pro 7.0.470.000, that is the firewall without ZA Antivirus, on windows XP SP2. This version of ZA blocks my attempt to install Kasperksy Antivirus 18.104.22.1685. Now my understanding of this is that ZA is using KA's Antivirus engine,
even in a ZA product that is not using this engine ZA is still causing a conflict.
I see no reason why the ZA firewall should block the KA Antivirus implementation, I could understand there being a problem if the ZA product I am using had active Antivirus built in. That would mean trying to run two Antivirus solutions at the same time, I would expect a conflict. In my case I am running two separate solutions that should not conflict.
I have seen similar posts on the forum but have not seen a response that indicates if this problem is going to be fixed, either by Kasperksy or ZoneAlarm.
