I'm new at Unity, and I'd like to know what program I use to edit Java scripts

I don’t want to download monodevelop because it looks as if there is a virus. On the website I have to download extra stuff to get monodevelop. Do you know any other programs I could edit Javascripts with?

MonoDevelop. You don’t download it; it’s included with Unity. It doesn’t have any viruses.

JavaScript scripts (and csharp scripts, for that matter) are just text files. You can edit them in any text editor - notepad or MS Word, if you really wanted to. However, you’ll find it easier in a dedicated code editor to benefit from things like syntax-highlighting and auto-complete.

If you really don’t want to use monodevelop that comes with Unity, check out Visual Studio Express or Notepad++
