Can you tell me where I can find that setting in Windows 11? I have looked for it and the closest I can get is shown in the attachment. Where or how can I get both to run in Windows 11? Notice the setting that is "Off" under Windows Defender Antivirus Options" say periodically check for threats. That's not real time, is it?"If you wish to have 'both' Malwarebytes Premium (not free) 'and' Windows Defender active at the same time go to Settings, Security then switch off Always register Malwarebytes in the Windows Security Center. Defender will no longer see Malwarebytes as being active and Defender will be enabled."
