Anonymous people are playing around with my iTunes. How to stop? Help?

Question

okay since 6 hours ago some creepy people are playing around with my iTunes. I believe its people who live around my building. I have my iTunes on and this anonymous person is playing controlling my library by changing the songs to the ones that the like. I don't know if this has anything to do with iPod or iPhone remote applications. Shouldn't they ask for passwords if they want to get into my library? But it's not!
I do turn on "Share Library" but I tried something: Usually when you press the red exit X, shouldnt they say "Some other users are on your library, are you sure you want to quit?" But it doesnt ask that.
I am on wireless and when I turn off my wireless it doesn't happen. Nobody disturbs my library. I recorded some "Quit doing it" audios and put it into my library but they're still doing it.
I don't know if it's a virus (I need to get a new antivirus). I dont think it's virus though because it also happened to my sister's laptop. She closed her iTunes so the anonymous wont bother anymore. They're still doing it right now to my laptop!!!
I asked this question on Yahoo! Answers and a person said something about my wireless getting hacked. What should I do????
How do I make this stop??? HELP PLEASE!!!!!!!!!!!!!
Please give me step by step instruction because I fail at fixing my computer.

Anyone hacking your wireless would just obtain access to your Internet connection, not to your computer.
If someone is actually changing your library, then they almost certainly have access to your computer itself. The Sharing built into iTunes only allows someone to play your shared playlists; other users have no ability to make any changes. It's possible that someone is connecting via iPhone Remote; go into the iTunes -> Devices preference and click the "forget all remotes" button. If someone managed to connect Remote, that should cut them off.
Otherwise, it's probably not an iTunes problem as such but rather that someone's hacked into your computer. I can't give you step-by-step instructions since there are many possibilities as to how someone might have obtained access to your system. But I'd suggest you start by making sure that you don't have Windows file sharing turned on; if you do turn it off for all shared volumes/folders. The same would apply to Windows remote desktop; you want to make sure that's turned off.
If none of that helps, you'll probably need to take this problem up on a web site oriented to Windows support since it's, as I said, most probable that someone is hacking into your computer.
Good luck.
