If you’re experiencing a constant inexplicable 30%-50% CPU spike on the latest version of Windows 10, and Task Manager CPU usages don’t add up to the total amount of CPU that is being taken away, and you have a copy of Prey 1.6.2 or later installed, and you’re running Windows Defender for antivirus protection, uninstall Prey.
