How do I remove Limewire from iTunes?

Question

Hi!
Being a polite person, I'm taking Dave Sawyer's (aka "Miss Manners") kind advice and posting a new question on this old topic.
Along with the plethora of other problems that have overtaken my iMac since the "upgrade" to OSX 10.5.7, iTunes is displaying unwanted Limewire connections. These are displayed as "shared libraries." This was apparently fallout after a Windows PC user on my (currently disabled) home network downloaded Limewire.
Understandably, since Limewire has a reputation as being used for less than legal purposes, I desire primarily to remove it and any vestige of it from my computer. Secondly, I'd like to be able to share iTunes between accounts on my iMac, as I used to be able to.
Specifically, I don't consider simply turning off "look for shared libraries" to be an answer. It seems akin to covering your eyes when you see you're going to crash your car.
I am able to stream music from these "shared libraries", and so have disabled sharing in iTunes Preferences. If anyone has an answer that will allow me to turn sharing back on with a certainty of not being "connected" to some anonymous strangers Limewire program, I'd truly appreciate it.
Regards.

you could perhaps block port 3689 (iTunes Sharing) and 5353 (Bonjour) in your router to your cable network. That would probably block those libraries from appearing while still allowing sharing within your own home.
Many thanks to you both, Dave & Meg! Being a polymath rather than a code warrior (I'm somewhat dyslexic };) ), I appreciate your able assistance. And Meg, you're quite right about Miss Judith, and we need more folks with good manners.
I have seen reports that Limewire could possibly access http, and therefore data files, on Windows computers. As far as you know, could this be accomplished through the iTunes application and browser, and on a Mac?
I ask this because iTunes often links to Safari, and though not a Luddite, I'm suspicious of technology that's designed for an inherently less than honest purpose, such as Limewire. Could it exploit the above port for this purpose?
