You can avoid this issue with Spybot by following the instructions below.
Please go to:
Start Center > Settings (tick "Advanced User Mode" if you do not see "Settings") > System Services
Here, click "Stop" beside "Security Center Service". Untick "Active after every reboot" for this service.
Click "Apply" and "OK", and reboot your PC.
When it restarts, you should be able to run Defender with Spybot, as Windows will no longer see Spybot as a potentially conflicting antivirus program.
