Once the fix has been completed, please attach the file FIXLOG.TXT to your next reply

Farbar program:   FRST64.exe

Save the attached file:  FIXLIST.TXT to this folder C:\Users\nated\Downloads\

NOTE. It's important that both files, FRST64.exe, and fixlist.txt are in the same location or the fix will not work.

Please make sure you disable any real-time antivirus or security software before running this script. Once completed, make sure you re-enable it.



Run the Farbar program with Admin rights and press the Fix button just once and wait.

I downloaded the free online scanner from F-secure a while back before the malware, and before I downloaded malwarebytes. though I'm not sure if it's still running anymore, or how to stop it if it is

I uninstalled Mcafee, Adobe, and the old 7-Zip. I'm pretty sure I updated the rest.

I see the issue. You have another missing service that is related to Windows Updates

Please run the following fix while I go grab the correct files to fix that service


Save the attached file as before to this folder:  C:\Users\nated\Downloads\


Then run the Farbar scanner with Admin rights and click on the FIX button.

When done, please attach the updated FIXLOG.TXT file to your next reply.

Please saved the attached file:  RepairServices2.zip  to your computer. @NC1210


Extract the files to your C:\FIX folder


Then, as before. Run the NirSoft AdvancedRun tool with Admin rights. All the same settings for C:\Windows\System32\cmd.exe 

Then click the Run button to open the DOS window.

Then the same as before


Then copy and paste the following and press the Enter key

reg import DoSvc.reg


Then copy and paste the following and press the Enter key

reg restore "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DoSvc" C:\fix\DoSvc.HIV


Then restart the computer and see if Windows Updates work now or not and let me know.
