PUP.Optional.Legacy false positive?

Recommended Posts


I have recently run a scan with adwcleaner and it has detected these registry keys:

PUP.Optional.Legacy             HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall\{2B51C83A-465D-4EA9-9CDC-1ED95ED09AC6}
PUP.Optional.Legacy             HKLM\Software\Microsoft\Windows\CurrentVersion\Installer\UserData\S-1-5-18\Products\A38C15B2D5649AE4C9CDE19DE50DA96C
PUP.Optional.Legacy             HKLM\Software\Classes\Installer\Products\A38C15B2D5649AE4C9CDE19DE50DA96C
PUP.Optional.Legacy             HKLM\Software\Classes\Installer\Features\A38C15B2D5649AE4C9CDE19DE50DA96C
PUP.Optional.Legacy             HKLM\Software\Wow6432Node\Classes\AppID\OverlayIcon.DLL
PUP.Optional.Legacy             HKLM\SOFTWARE\Classes\AppID\OverlayIcon.DLL
PUP.Optional.Legacy             HKLM\Software\Wow6432Node\Classes\TypeLib\{ADF1FA2A-6EAA-4A97-A55F-3C8B92843EF5}
PUP.Optional.Legacy             HKLM\Software\Classes\TypeLib\{ADF1FA2A-6EAA-4A97-A55F-3C8B92843EF5}
PUP.Optional.Legacy             HKLM\Software\Wow6432Node\Classes\Interface\{7BCA6879-A9F8-47DE-AE05-F5CE7EA3A474}
PUP.Optional.Legacy             HKLM\Software\Classes\Interface\{7BCA6879-A9F8-47DE-AE05-F5CE7EA3A474}

Can I safely delete them or are they false positives? Thanks in advance!
