Hi Thomas,

I am using Panda Internet Security 2007, which has the same firewall
base component as Panda Antivirus 2007. Having FB 1.5.3 SuperServer
installed I have no problem with it (same as your case), although I
had to configure the Panda firewall to accept outgoing (client) calls
for FB to work correctly. Maybe Classic version needs it to be
configured as either incoming (server) or both allowed.

Said this, are you sure the Panda firewall was really not installed?
If it affected your system and was not detected as malware by the
antivirus, then it could be that Panda's firewall was active at the
same time as your ZoneAlarm.

Best regards,
