Sorry about that, but I have no idea what the problem could be. I don't use Avast so I have no idea how to resolve this issue. The download .exe is created by WinRAR, so not exactly unusual. Did any of the previous versions give this problem?
I haven't done any work on the EDDL over Christmas/New Year, but I do have a couple of things in mind so expect some updates in the near future.
Was looking into this - sorry to say that not only avast's heuristic thinks the actual version is a trojan. 360 Internet security and bit defender warn about it too.
