title: Security Warning when running scripts - Unblock-File not unblocking file
body: <p>I suddenly started to recceive this warning when running any script on my computer:</p>
  
  <blockquote>
    <p>Run only scripts that you trust. While scripts from the internet can be useful, this script can potentially harm your computer...</p>
  </blockquote>

  <p>The files are not blocked.</p>
  
  <p>I have</p>
  
  <ul>
  <li>checked in File Explorer > Properties.</li>
  <li>used the <code>Unblock-File</code> cmdlet to unblock as well.</li>
  <li>checked streams using cmdlet: <code>Get-Content -Path '\\Path\Script.ps1' -Stream Zone.Identifier</code>. No Streams found.</li>
  <li>used Streams.exe from Sysinternals: <code>streams.exe -d \\Path\Script.ps1</code>. No files with streams found.</li>
  </ul>
  
  <p>Also tried to remove streams with Powershell:</p>
  
  <pre><code>Remove-Item -Path \\Path\Script.ps1 -Stream Zone.Identifier
  </code></pre>
  
  <p>Of course without success as there are no streams.</p>
  
  <p>Execution policy is Unrestricted.</p>
  
  <p>When I run Set-ExecutionPolicy Bypass it works without warning.
  It should, however, also work when it's unrestricted.</p>
  
  <p>I honestly don't know what's going on.</p>
