Since upgrading from NOD32 AV to the smart security suite I have had numerous system crashes on what was a very stable win XP box. Crashes always occur when a new program access brings up the firewall permission dialogue box (in the firewall's interactive mode). Sometimes the dialogue box appears but I have no time to give permission before the system crashes, sometimes I don't even get to see the dialogue box. Since disabling the firewall (AV still running) and going back to using ZoneAlarm Pro the system has become stable again. Anyone else suffering from this buggy firewall?
