Quick Update:
After unnistalling Adobe Creative Cloud and all its applications as suggested, killing all processes and re-installing - the problem persited.
I got tired of fighting the issue, so I went on a break and let the computer alone for a couple of hours while the fans ran at their full and the CPU was 100%. When I came back CPU was normal, no more crazy fans.
Not sure if whatever process the CCXProcess was running finished and it was just something that took a lot of CPU and a loooong time to complete.
I am just glad my computer is back to normal.
Daniel, and others, I am sorry that you continue to see high CPU usage. This public discussion thread is currently full of both individuals and people who work for organizations that manage their membership and computers.
