I finally ran the MalwareByte full scan successfully. It finishes in 1hr 36 min w/o freezing and the computer is clean. However, when I save the log, I thought that I saved it into my jump drive. Later I couldn't find it. So I used the Search to find a *.txt modified today in the C drive.

What I get is some funny results, it search my jump drive as well and display the log file created by the quick scan repeatedly until I click Stop. If I specify search on the jump drive only, it won't search the C drive and won't repeat the results.
