WMI Provider Host process chewing up CPU

[durnik56]

I've got a WMI Provider Host process running on my Windows 8 machine that's using ~30% of my CPU constantly. This has got to be some sort of malware that got into this system. How do I get rid of this?

FRST.txt

[kevinf80]

Download attached fixlist.txt file and save it to the Desktop, or the folder you saved FRST into.

NOTE. It's important that both FRST and fixlist.txt are in the same location or the fix will not work.

 

Run FRST and press the Fix button just once and wait.

The tool will make a log on the Desktop (Fixlog.txt). Please post it to your reply.

 

Next,

 

We need to run an online AV scan to ensure there are no remnants of any infection left on your system that we may have missed. This scan is very thorough and well worth running, it can take several hours please be patient and let it complete:

 

Run Eset Online Scanner

 

**Note** You will need to use Internet explorer for this scan - Vista and win 7 right click on IE shortcut and run as admin

 

Go to Eset web page http://www.eset.com/us/online-scanner/ to run an online scan from ESET.

 

• Turn off the real time scanner of any existing antivirus program while performing the online scan
  
• click on the Run ESET Online Scanner button
  
• Tick the box next to YES, I accept the Terms of Use.
  Click Start
  
• When asked, allow the add/on to be installed
  Click Start
  
• Make sure that the option Remove found threats is unticked
  
• Click on Advanced Settings, ensure the options
  
• Scan for potentially unwanted applications, Scan for potentially unsafe applications, and Enable Anti-Stealth Technology are ticked.
  Click Scan
  
• wait for the virus definitions to be downloaded
  
• Wait for the scan to finish
  

 

When the scan is complete

 

• If no threats were found
  
• put a checkmark in "Uninstall application on close"
  
• close program
  
• report to me that nothing was found
  

 

If threats were found

 

• click on "list of threats found"
  
• click on "export to text file" and save it as ESET SCAN and save to the desktop
  
• Click on back
  
• put a checkmark in "Uninstall application on close"
  
• click on finish
  

 

close program

 

copy and paste the report in next reply

 

Next,

 

Download Security Check by screen317 from either of the following:

http://screen317.spywareinfoforum.org/SecurityCheck.exe or http://screen317.changelog.fr/SecurityCheck.exe

Save it to your Desktop. (If your security alerts either accept the alert, or turn the security off while Secuirity Check runs)

Double click SecurityCheck.exe (Vista or Windows 7 users right click and select "Run as Administrator") and follow the onscreen instructions inside of the black box. Press any key when asked.

A Notepad document should open automatically called checkup.txt; please post the contents of that document.

 

Let me see those logs, also give an update on any remaining issues or concerns..
