High Cpu & Memory Usage When At Idle - Logs Attached

Those logs are clean of malware. However, doubling the installed RAM of this machine would be beneficial.

If you are not having any other malware problems, it is time to do our final steps:

1. We recommend you keep Malwarebytes Anti-Malware for scanning/removal of malware. Unless you purchase it, it provide no protection. It do not use any significant amount of resources ( except a little disk space ) until you run a scan.
2. Go back to step 6 of the READ ME and re-enable your Disk Emulation software with Defogger if you had disabled it.
3. If running Vista, Win 7/8/10 - it is time to make sure you have re-enabled UAC by double clicking on the C:\MGtools\enableUAC.reg file and allowing it to be added to the registry.
4. Go to add/remove programs and uninstall HijackThis.
5. Go to the C:\MGtools folder and find the MGclean.bat file. Double-click on this file to run this cleanup program that will remove files and folders related to MGtools and some other items from our cleaning procedures.
6. After doing the above, you should work through the below link:

Replying to your points first, then we'll go further:

• I would expect some sluggishness using Win 7 + 2.2GHz Single Core processor + 2GB RAM (660MB available)
• Configure Process Explorer differently to aid tracing processes and handles
  • Once opened, select Options
  • Put ticks by "Verify Image Signatures", VirusTotal.com > Check VirusTotal.com, Confirm Kill
  • At the far right you will see the VirusTotal column showing scan returns of running processes
• It is not unusual to hear that Combofix won't run on some particular machine... have had reports of this in my threads and have experienced it myself.

Next, please download and run Zemana AntiMalware.
When the scan is completed, view my attachment for how to retrieve the log. (Click the icon high-lighted by the arrow, mouse-click the latest System scan then click on the "Open Report" radio button). Upload that log also, please.

Question: Has the owner had problems with Windows Updates possibly failing lately?

 

Under the far right column under VirusTotal, those numbers in blue are the results of each process being evaluated by the VirusTotal scan engines.

0/56-57 means not infected​
