Norton Internet Security Issue.
Unfortunately currently Norton Antivirus often flags the windows installer as a virus, often this happens with each new revision until enough users report the issue as a "False Positive". So please report a problem with a false positive to Norton.
The way round this issue is to turn off Norton's 'Download Intelligence' while you install. On a new machine you will find this option on the advanced panel, there is a set of slders down the left and at the bottom is labeled "Download Intelligence", turn it off until you have installed haxe.
