Yes that is correct, you would have to remove avast for Defender to become active again, this is because Defender on windows 8 is a full antivirus and not just spyware as it was on earlier versions of windows.
If you want to run an extra second opinion scanner then Malwarebytes would be the most recommended program to use and it’s free, their paid Pro version also works in real time with avast without conflicts.
