PUP.Optional.NotChromeRun is Malwarebytes’ generic detection name for values under the registry key HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run, that point to a file called Chrome.exe. However, the said file is not the actual Chrome browser executable. In most cases, this is a Chromium build that is planted by malware or PUPs.
PUP.Optional.NotChromeRun is a “removal only” detection and does not offer protection.
Malwarebytes can detect and remove PUP.Optional.NotChromeRun without further user interaction.
When PUP.Optional.NotChromeRun is detected on your computer, Malwarebytes for Windows does not know whether it was authorized.
