Itunes..computer..disaster?

hi! i had already installed itunes onto my computer then tried to uninstall it. thats where the problem is. see in add or remove programs (in control panel) itunes, bonjour, quicktime etc. was still there. so i pressed uninstall and it said the feature you are trying to use is on a network source that is unavailable blah blah blah. ive tried everything, ive read all the articles, but nothing works. if you could also make it so i could get itunes 10.1 that would be great, but i just want it to go away!! plz help :()()
