Oops, it was a typo on my part. I meant McAfee Internet Security! I don't see a way to edit or delete my post so I will start a new one.. Sorry.
Oops indeed, LOL. I edited the main post - hopefully correctly. As we Mods don't use MAC's I'm hoping someone with knowledge will answer you soon, otherwise there is always Technical Support which is free of charge.

Search down in the posts here... I posted the ports you need to open in the firewall to get the TimeMachine/Airport stuff to work properly with the software. McAfee tech support is useless. It took them half an hour to realize I wasn't running on a PC. When they got to the MAC the best they can suggest is to reinstall the software.
TRY THIS (reposted from the earlier thread):
The TimeMachine backups need Bonjour to find the disk (the TimeCapsule or whatever your destination is). You need 1900/UDP enabled for the thing to find the backup disk. Also enabling 5353/UDP makes the Airport Utility discovery stuff work. The file transfer is on 548/TCP (Apple Filing Service). This is outbound only from your client so you shouldn't need a rule for that.
There's definitely some bugs in the "Manage Rules" system on LiveSafe. Periodically pressing SAVE causes it to put in different ranges than what was typed (sometimes just reverting to some old version). Further Save and even sometimes closing the windows doesn't cause the rules to be applied. I found that sometimes I need to twiddle from Public to Home/Work and back again to get the rules to switch.
