After removing Sophos from a Windows 11 Pro laptop and adding Windows Defender as a replacement, the Security tab under a device shows both security solutions as being active:

 

 

I checked both the "Program Files" and "Program Files (X86)" folder and removed a single, empty Sophos folder, just to be sure. There are no processes active on the laptop for Sophos. It seems like it just shows the 'ghost' of Sophos.

Hey @Peter-MbIT

Try restarting the Pulseway service and it should rectify the issue - if not let me know and will reach out to support! 

Thanks
