Nope, it is just that windows updates was restored when combofix was completed.  Could you attach the combofix log please

OK services is still infected, I need to find a spare copy to replace it with.
Complete the OTL fix and then run this scan
There will be just one log this time 


  • Double click on the icon to run it. Make sure all other windows are closed and to let it run uninterrupted.


  • Select All Users
  • Under the Custom Scan box paste this in
netsvcs
BASESERVICES
%SYSTEMDRIVE%\*.exe
/md5start
services.*
/md5stop
dir "%systemdrive%\*" /S /A:L /C
CREATERESTOREPOINT


  • Click the Run Scan button. Do not change any settings unless otherwise told to do so. The scan wont take long.
    • When the scan completes, it will open two notepad windows. OTL.Txt and Extras.Txt. These are saved in the same location as OTL.
    • Post  both logs

OK found a spare :)

1. Close any open browsers.
 
2. Close/disable all anti virus and anti malware programs so they do not interfere with the running of ComboFix. 
 
3. Open notepad and copy/paste the text in the quotebox below into it:
 
Quote

FCopy::
 C:\WINDOWS\winsxs\amd64_microsoft-windows-s..s-servicecontroller_31bf3856ad364e35_6.1.7600.16385_none_2b54b20ee6fa07b1\services.exe | c:\windows\system32\services.exe

 

 
Save this as CFScript.txt, in the same location as ComboFix.exe
 
 
 
 
Refering to the picture above, drag CFScript into ComboFix.exe
 
When finished, it will produce a log for you at C:\ComboFix.txt which I will require in your next reply.

OK first we will use the easy solution, which is to run the MSFixit located here  http://support.microsoft.com/mats/windows_update/

Let me know if that cures the problem

not asking to update anymore, seems to be working fine. Still pops up with a box asking me to approve of microsoft malicious software removal but i just click no and its fine. no big deal really. thanks so much essexboy, computer is running notably faster and no more virus alerts from avast either, very happy.

Subject to no further problems   :)

I will remove my tools now and give some recommendations, but, I would like you to run for 24 hours or so and come back if you have any problems 

Now the best part of the day ----- Your log now appears clean  :thumbsup:

A good workman always cleans up after himself so..The following will implement some cleanup procedures as well as reset  System Restore points:

Remove ComboFix
  • Hold down the Windows key + R on your keyboard. This will display the Run dialogue box
  • In the Run box, type in ComboFix /Uninstall
     (Notice the space between the "x" and "/")
    then click OK



  • Follow the prompts on the screen
  • A message should appear confirming that ComboFix was uninstalled
Run OTL and hit the cleanup button.  It will remove all the programmes we have used plus itself. 

Clear Restore Points

Go Start > All Programmes > Accessories > System tools
Right click Disc Cleanup and select run as administrator
When it pops up at the first prompt select OK after it has done some calculations the tabs will appear
Select More Options tab
Press Sytem Restore and Shadow Copies Cleanup button



: Keep Java Updated :

WARNING: Java is the #1 exploited program at this time. The Department of Homeland Security recommends that computer users disable Java
See this article and this article.
I would recommend that you completely uninstall Java unless you need it to run an important software.
In that instance I would recommend that you disable Java in your browsers until you need it for that software and then enable it. (See How to diasble Java in your web browser and How to unplug Java from the browser)

Now that you are clean, to help protect your computer in the future I recommend that you get the following free programmes:

Malwarebytes.

Update and run weekly to keep your system clean

Download and install FileHippo update checker and run it monthly it will show you which programmes on your system need updating and give a download link

If you use on-line banking then as an added layer of protection install Trusteer Rapport

It is critical to have both a firewall and anti virus to protect your system and to keep them updated. To keep your operating system up to date visit To learn more about how to protect yourself while on the internet read our little guide  How did I get infected in the first place ?Keep safe  :wave:
