After some problems with Juno, I tried uninstalling Julia and Juno (including deleting related folders under Users: “.atom” and “AppData/Local/Julia”) and installing from scratch.

The first difficulty was that `Pkg.update()` asked to run `Pkg.init()` first, but this fails with

```julia
ERROR: GitError(Code:ERROR, Class:OS, Failed to mark Git repository folder as hidden: )

```

This was fixed by rebooting and running `Pkg.init()` again (I also tried manually marking the folder as hidden, but that did not help before rebooting, so I don’t know if it mattered).

After installing the uber-juno package and restarting Atom, the new REPL view says “Press Enter to start Julia”. When pressing Enter I got `Starting Julia...`, but no further output. Pressing Enter again yields more copies of the `Starting Julia...` message.  
After restarting Atom and trying again, I get the following:

```julia
Press Enter to start Julia. Starting Julia...

```

Running `Pkg.add("Atom")` in Julia yields the same error.

Any ideas how to proceed would be appreciated.

In case anybody else encounters these problems: I found both of the issues in my first post were caused by McAffee Endpoint Security finding julia.exe “suspicious”. Reinstalling McAffee fixed it for now.
