As Eddy said, its just Zonealarm doing whats it suppost to do, what it is telling you above is that ZA thinks that someone is port scanning your computer looking for a Trojan on there that a user could use to gain access to your computer, the port it was scanning was port '7000' which is rarely used by 'safe' programs, so ZA checked your program control section and determined there was no Trojan on your computer.
To sum it up, your computer is safe.
This answer your question?
