Could you continue with combofix now please
yes it just ended. (See attached file)
I thought each service from Avast was disabled, but avast bloked Rootkit.exe (something like that) at the end of the precess... it happened very quick, then reboot...

OK we will need to do one more run with combofix

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.exeWhen finished, it shall produce a log for you at C:\ComboFix.txt which I will require in your next reply.

Notes:
1. Do not mouse-click Combofix's window while it is running. That may cause it to stall.
2. Do not "re-run" Combofix. If you have a problem, reply back for further instructions.
3.  If after the reboot you get errors about programmes being marked for deletion then reboot, that will cure it.

I do not have any messages from avast every minute, this is already a good point !  :) And Chrome is opening immediately (it used to freeze then nothing happening...)...
So i would say that it is a kind of miracle !

What an adventure !
My PC and i thank you a thousand times for your professionalism and patience ! You're the best !
Thank you very much !

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:

Run OTL
  • Under the Custom Scans/Fixes box at the bottom, paste in the following
    Quote
    :Commands
    [resethosts]
    [emptytemp]
    [Reboot]
  • Then click the Run Fix button at the top
  • Let the program run unhindered, reboot the PC when it is done
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. 

We will now confirm that your hidden files are set to that, as some of the tools I use will change that
  • Go to control panel
  • Select folder options (Appearance > Folder options in category view)
  • Select the View Tab.
  • Under the Hidden files and folders heading select Do not show hidden files and folders.
  • Click Yes to confirm.
  • Click OK.

Your Java is out of date. Older versions have vulnerabilities that malware can use to infect your system.
Please follow these steps to remove older version of Java components and upgrade the application.

 Upgrading Java:
  • Go to this site  and click Do I have Java
  • It will check your current version and then offer to update to the latest version
SPRING CLEAN

To manually create a new Restore Point
 
  • Go to Control Panel and select System
  • Select System
  • On the left select System Protection and accept the warning if you get one
  • Select System Protection Tab
  • Select Create at the bottom
  • Type in a name i.e. Clean
  • Select Create
Now we can purge the infected ones
  • GoStart > All programs > Accessories > system tools
  • Right click Disc cleanup and select run as administrator
  • Select Your main drive and accept the warning if you get one
  • For a few moments the system will make some calculations
  • Select the More Options tab
  • In the System Restore and Shadow Backups select Clean up
  • Select Delete on the pop up
  • Select OK
  • Select Delete
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

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:

Some news :

everything seems to work fine... now.

The only thing strange is these new and unknown folders on my second hard drive (E:) :

-$RECYCLE.BIN (-> empty)
-12e3d5b48621f00e774eec ( seems to be created by Microsoft, contains many folders and some bmp files with "Microsoft.Net" logo..)
-045d01d4963189aeb2b8ee658d (the same here)

I also had some problem with Windows Live update. nearly impossible to finilize the process. And then, LiveMail didn't work anymore (even with a reboot)...
I tried to restore the system but it failed (problem with Windows Live cache not found.. well.. if i remember correctly..)
I finally used Windows Installer Cleaup, uninstall, and finally install Livemail. And now it works ;o)

Those are windows updated locations, not a problem.  Each drive has its own recycle bin
