I cannot find Map Editor

I just bought the game a couple of days ago. Fortunately, some old maps from when I own the game on CDs still work but I cannot find the editor. Can someone help?

StarEdit was depreciated by Blizzard.

Now ScmDraft is your best option.

Use latest Scmdraft 2 alpha build.

So Blizzard doesn’t have a major component of the game with it anymore? Why? They are responding to me on support ticket.

Is the outside editor virus-proof?
