Antivirus frequently detecting Trojan Horse

Hello,

Chaslang helped me remove Trojan.Flush and Trojan Horse from my laptop earlier this week which is now free of infection, but I have my other laptop facing similar problems:

Symantec is detecting Trojan Horse from time to time.

I followed the basic steps and am attaching the logs.
Can you please review them and help me get rid of residual infection?

During the basic steps, the following things happened:

1. During MBAm scan, this msg appeared:
"An error occured. Please report the following error code to the Malwarebytes' Anti-Malware support team.

Error code: 731 (0,9)

When I reran MBAM ( which I probably shouldn't be doing though), the scan was smooth without any error - and it fixed the one problem thta it found during the scan

2. During the ComboFix scan, the Active Desktop was turned off by microsoft.
And at the end of the scan the machine was rebooted by ComboFix automatically.

Please help me fix the infection on my laptop.

Many thanks in advance.

Here is the 4th log from the scans.

 

I have also deleted an old version of Java that I noticed later.
