Re; RTProtectionDaemon
The "problem" persists with Malwarebytes full paid for version of their application with the RTProtection daemon sucking up most of the CPU, at least at startup. The solution remains the same as it was in 2017. Go to the Malwarebytes icon on the toolbar and click on Stop Malware Protection. This is different terminology to the older version but means the same.
In addition to that there is now an added feature called App Block. This will block the accidental installation of applications that may be initiated by clicking a link on a website.
This is good in a way but if you get a popup saying that the installation of a legitimate app that you want to instal has been blocked by Malwarebytes you may have to turn off (at least temporaliy) the new feature "App Block". This is done in the same way as with the above.
