It appears that you DID NOT reboot the computer after running MBA-M. At least one of the listings of infections found with MBA-M would have had this order at the end; Delete on Reboot. That means infection cannot be deleted until the computer is rebooted.
It shows in the log that the computer wasn't rebooted by this entry

O4 - HKLM\..\RunOnce: [Malwarebytes Anti-Malware (reboot)] "C:\Program Files\Malwarebytes' Anti-Malware\mbam.exe" /runcleanupscript

That wouldn't have shown in the log if the computer had been rebooted.
Please UPDATE MBA-M and run a NEW Full System Scan with it.
Be sure that everything is checked, and click Remove Selected

Then REBOOT the computer and run a new HJT scan, save the log.
Post back here with BOTH the MBA-M log and the new HJT log.
