Have you done the Safe Mode boot yet? You need to do that before going any further.
I just tried downloading iTunes from the link I posted and it opened OK so it's definitely something with your setup.
Once you do the Safe Mode boot try downloading and opening the iTunes installer again. Post back if you still have the problem.
I am now in safe boot mode on my computer, however now its not letting me connect to the internet in this mode... I am located in Australia at the moment and we have a "toggle" that we have to put in the USB outlet in order to use the internet. Its basically like dial up. Is there some way to allow internet connection in the safe boot modem? I'm writing from my phone. Thanks!

That's correct. The safe boot was just to do the disk verify/repair, since you didn't have the proper DVD. And no, there are a number of things you can't do in that mode.
If you still can't download, the problem is with Safari, or your internet connection, not the directory on your HD.
I ended up creating a wi-fi hotspot on my cell phone which I was able to use for my computer. In the safe boot mode I was able to update Itunes and Security so I am good to go, at least for now... So in the future, will I always have to download in safe boot mode? what is going on with my general sign in that isnt letting me? Thanks Pondini and Frank for all your help. I really appreciate it.

You certainly shouldn't have to, but at least you found a workaround.

Hard to tell. There may be a problem with your modem, internet connection, etc.
