Sending files using AIM

I use AOL Instant messenger to send my music to various people. Since installing Norton Anti-virus I cannot send or receive files through AIM. Even disabling it temporarily does not work. I have to uninstall Norton, send a file, then re-install norton and then download all the updates again. 

Surely there is a way to resolve this issue. Please help!!!

 

And detailed steps would be handy. Not just allow AIM in the firewall settings, because I don't know how to do that.

 

Cheers
