Giving your real IP address is not really recommended but it's not usually harmful (after all, every time you go to a website, its owner can see your address, and thankfully most of them have better things to do than attacking you).
Now, posting it in a message where you also explain you just turned off both your firewall and your antivirus will really get some attention from the bad persons.
Regarding the fact that you even consider turning those off, I would say the right answer for you is do not post your IP address anywhere!
Now, about your comments to previous answers: you don't have to turn off your firewall to allow connection to one server running on your pc. Just configure it to open the port you need.
Also I'm kind of sure disabling your antivirus will not help at all. Don't do that.
If as I assume you have issues to connect to a server running on your pc from outside your local network, the source of the problem is usually one of those two:
- you have a router, and you need to configure port forwarding on your router (not on your pc)
- your server software is configure to only accept local connections (connections originating from the same pc it is running on), and you need to change this setting (Google this since it depends of the actual server you're trying to configure)
Good luck!
