The Fixlist.txt log is complete and is the proper file; it appears the script ran as well as can be expected. How is your system running now? Are you still getting ExternalBlue warnings?

I noticed in the FRST scan logs that you had Norton and Avira on your system in some time past. There are still leftover parts of these software on your system. Please download and run the following Removal Tools to help clean your system:

Norton - Norton Removal Tool

Avira - KB for manual uninstall
