Q: "This type of file can harm my computer. Do I want to keep iTunes 10.6.3 anyway?
It sounds like the web browser is providing a general warning about the file type.
If you're trying to download iTunes from the Apple website (http://www.apple.com/itunes/download/), it's fine.
This Apple document might help you out, it has some good pics -> iTunes: Downloading iTunes for Windows using Internet Explorer
