Its a little difficult to say whether your being hacked, it kind of depends on the direction that the alarm is being sounded from, and who all uses or has used the computer.
Tracker-Tracker appears to be a central site where information regardingHotline and Carracho.
Hotline and Carracho are both person to person file transfer systems, similiar in nature to a Napster. A means by which one person can share files with another using the internet. Currently P2P systems depend on a network ofcomputers working together to form a virtual computer if you will. In order for this to work there is a lot of communication by the software telling other computers it is there and ready to participate and do its part.
Both of these seem to be associated largely with people interested in or associated with Independent films, and animated films and games.
So the which direction means if Zone Alarm is saying xyz has tried to enter and I stopped it. Well at one time this computer might have had these programs and became listed as a participant and the rest of the network is trying to talk to it.
If however, zone alarm is saying this program or this action want to access the internet, well in that case there is a piece of software that is running that wants to make contact with the central area, probably for update info, of what ever nature it does.
I said it also depends on who uses the computer.
If no one who uses the computer knows ANYTHING about this then yes you might have been in a sense hacked, but not in the sense of a virus. Hacked by doing something on the internet that caused this software to be used/loaded.
