PUP.Optional.NotChromeRun is a generic detection 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.
