Problem is that a trojan can still give out information from your PC
from behind a NAT connection.
You download something that has a trojan and run it....the trojan
looks for any interesting data and sends it to the person who wrote or
configured the trojan.
Zonealarm prevents this by letting you authorise the programs that can
send out data. so if for example notepad tries to access the internet
zone alarm will ask you if you want to let it...I would suggest not ;)
