Thank you for the info!

I was seeing errors on far more directories than just Safari Extensions:

and that's only 15 seconds' worth, so it seemed reasonable to assume it might impact performance with that high of an error rate.

[RTProtectionDaemon Full Disk Access on Mojave]

During my Premium trial, I noticed many "RTProtectionDaem" file system permission deny errors in the Console app when running on Mojave.

I decided to try adding /Library/Application Support/Malwarebytes/MBAM/Engine.bundle/Contents/PlugIns/RTProtectionDaemon.app to Full Disk Access in System Preferences / Security & Privacy:

After that all the Console errors stopped, and I also noticed a reduction in CPU usage for RTProtectionDaemon.

I couldn't find any info regarding this in the user manual or on the forums, so I just thought I'd post it in case it might help anyone else is seeing issues with Premium on Mojave.
