If you're encountering this, please try to submit it to https://www.microsoft.com/en-us/wdsi/filesubmission to report it a false positive.

@niheaven It seems the false positive is raised because of the patch #5901

v0.3.1 https://www.virustotal.com/gui/file/43369f44e355a81dc2c1379ff05f9e00aca2d3c420501d9b9c2577d8093217c8

Wow, I'll use Invoke-WebRequest instead and fix the issue.

@niheaven I would like to add that scoop checkup - which I would gess is what many users would turn to to check if there are any issues - doesn't report any problems even when the .ps1 file is missing:

PS C:\Users\xxxxx\scoop\apps\scoop\current> git status
On branch master
Your branch is up to date with 'origin/master'.

Changes not staged for commit:
  (use "git add/rm <file>..." to update what will be committed)
  (use "git restore <file>..." to discard changes in working directory)
        deleted:    lib/autoupdate.ps1

no changes added to commit (use "git add" and/or "git commit -a")

PS C:\Users\xxxxx\scoop\apps\scoop\current> scoop checkup
No problems identified!

I think that update functionality being disabled due to Windows Defender would qualify as a ... rather serious problem in my opinion.

Also affects new installs; here in docker making is more difficult to exclude from virus scanner.
