Hello,

I've detected infection and try to remove it with different tools :

  • Malwarebytes
  • CCleaner
  • Hijackthis
  • SuperAntispyware
  • SpyBot
  • BitDefender Rescue cd
  • Kaspersky Virus Removal Tool
  • Kaspersky Resource Kit (boot cd)
  • Windows Security Essentials

I've cleaned different type of infections :

  • Trojan HorseCrypt.AQLW
  • Trojan Dropper.Win32/Sirefef.B
  • Trojan Download.Win32/Obdov.H

Since, my Windows Firewall and my local area connection won't work.

ComboFix alert me that I was infected by RootKit ZeroAccess.

In attach, the logs of dds and HiJackThis

Hi again,

CF-SCRIPT

-------------

We need to execute a CF-script.

  • Close any open browsers.
  • Close/disable all anti virus and anti malware programs so they do not interfere with the running of ComboFix.
  • Click Start > Run and in the box that opens type notepad and press enter. Copy/paste the text in the codebox below into it:


MIA::
c:\windows\system32\drivers\netbt.sys
c:\windows\system32\drivers\tdx.sys

Save this as CFScript.txt, in the same location as ComboFix.exe

CFScriptB-4.gif

Refering to the picture above, drag CFScript into ComboFix.exe

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

Unfortunately we need to replace two missing files. No copies seem present. Can you do the following and then rerun combofix and post me the new log?

Click Start > All Programs > Accessories, right click Command Prompt and select "run as administrator".

Type sfc /scannow and press enter. Let the system file checker run unhindered.

Please navigate to the following files, right click them and select Copy. Then go to an usb drive, right click in an empty space and select Paste.

c:\windows\system32\drivers\netbt.sys

c:\windows\system32\drivers\tdx.sys

Now on the problem computer, insert the usb drive, select the files and right click > Copy. Navigate to c:\windows\system32\drivers and right click in an empty space > click Paste.

After that rerun combofix and post me the new log.

As indicate in the log in attach, the computer receive an IP address from DHCP and could connect on Internet.

But no "Local Area Connection", i'm still unable to connect on different map network drive.
