You're welcome, and thank you very much for contacting Spybot support. Please tell them everything you told me here, especially about the Windows Defender Security Center popup.

Also, ordinarily it is best to only run one resident (real-time protection, live protection, etc.) at a time. For that reason Windows Defender will shut it's real-time protection off when it detects another antivirus. However, for the time being in light of the Windows Defender popup saying that Live Protection is off sometimes, it's probably best for you to make an exception and see that Windows Defender real-time protection is turned on until you hear back from Spybot support and everything is resolved, as an extra precaution. You could follow the instructions on this page to see if Windows Defender's Real-Time protection is set to on or off:

If it is set to off, you could follow this page to turn on Windows Defender real-time protection for the time being until everything with Live Protection and the Windows Defender Security Centre popup is resolved:
