ZoneAlarm protection from port ??? question

This pos up every 5 minutes. I have no clue what it means. I clicked on 'more info' but I still don't understand. Does this mean someone is trying to access my computer every few minutes?
I know I can put a check in the 'don't show me this again' box and I am about to do just that as soon as I find out what it is
Hopefully there is not any personal info about my computer in this picture, if there is please erase it for me,, quick
Thanks!

 

It is ZA Blocking Incoming . CK the No Show

 

Hello,
Your firewall informs you of attempts at your ip - not your computer. Every second, millions upon millions of computers are routinely scanned for open ports and services listened to these ports for possible exploits. This is nothing personal and unusual.
Your firewall is doing the job of a gatekeeper and informing you of every attempt. Nothing to be alarmed off. You can safely ignore these prompts, because you really do not need to know this information. Your firewall seems to be doing its job.

Nothing to worry about.

 

Thanks everyone
So does that mean if I did not have the firewall protection that anyone could use my IP to get on the internet and look up whatever they want to? And if it was illegal, since it is my IP they are using I would be the one in trouble? Just curious how it all works since I am kinda slow about computers sometimes, lol
Thanks again!
