\*tl;dr : \*  
_I get an antivirus hit when I install the ZMQ package. Unsure what it means. It is of no consequence to me as of now._

Hi! Unsure where to post this, but I just wanted to raise this particular issue just in case it is a symptom of something sinister.

It is probably just a false positive, but the after I installed Juno in Atom, I got an antivirus hit (with NOD32) while downloading the packages during the initial startup of julia. I got it on both my desktop and laptop computer. Just to make sure, I tried again today : I uninstalled julia, reinstalled it and tried to add the package that generated the hit (ZMQ) and I still got the error.

Sorry for the french part of these, but I think you’ll all get the gist of it. First, here’s the error in the console :

```julia
julia> Pkg.add("ZMQ")

```

The WebClient error is due to my AV blocking the connexion. Here is the AV message :

 ![julia_urlik](https://global.discourse-cdn.com/julialang/original/3X/6/f/6f4b13b170426891e84027249e8ceb681bb5568f.jpeg)

I could not find any information regarding the URL/Urlik.G menace, however.

I don’t really need any kind of workaround as I am able to do everything I need for the moment without that package, but I thought it best to at least let people know in case it is more than a false positive.

Have a great day, all!

I had the same problem.  
After some digging, I found out it was a problem with PowerShell 1.0  
If you download Powershell 7.0 and replace powershell.exe with powershell 7, it will solve the problem
