Antivirus and Anti Malware Problems
If you are experiencing performance problems during Scoop installs—like high CPU usage, or file access denied errors—it's possible that an anti-malware or anti-virus program is scanning files as they are being extracted and installed.
You can exclude the directories that Scoop uses from realtime scanning by running this command as an administrator:
Add-MpPreference -ExclusionPath "$($env:programdata)\scoop", "$($env:scoop)"
If you want to undo this change and re-enable realtime scanning of these directories:
Remove-MpPreference -ExclusionPath "$($env:programdata)\scoop", "$($env:scoop)"
