Hi All,

It seems a common problem with Zero Access rootkit is no working network after its removal.

Unfortunately I have that problem on XP SP3.

A google search result caused the laptop to get something nasty which was only half noticed by Trend AV and stopped MBAM loading. MBAM could be reinstalled in safe mode and would remove stuff when ran, but a boot into normal mode brought it all back and broke MBAM. Eventually running combofix round and removed ZeroAccess, but there is now no working LAN/WLAN. Scans with Trend & MBAM locally now find nothing and putting the HD in another PC and scanning it again with MBAM and MSE find nothing too...

So HD now seems clear but WLAN shows no connectivity. A "netsh int ip reset" causes WLAN to connect but it gets no DHCP address, same problem exists for cabled RJ45 connection... the lights are on but nobody is home. Forcing a static IP does not help. Removing the NICs from Device Manager cause it to be redetected/reinstalled but problem persists, also booting after using MSCONFIG to disable all startup entries and stop non microsoft services doesn't help either. No working LAN.

But the LAN/WLAN works fine if you boot into safe mode.

There is no useable restore point.

I see people asking about this problem in forums but no working solutions.

Does anyone have a clue ?

Thanks

JF.

Forgot to say, TDDS found nothing... Only combofix found ZeroAccess.

Host file is OK and no proxy is configured.

Attached is a DDS log of pc running with normal boot, not safe, but with all non microsoft services disabled, and startup items disabled.

Log has dates in it...20th Oct was when it broke..anything before that is OK.

PC works fine, but no network.....

    • Please do this even if you have previously posted logs for us.
    • If you were unable to produce the logs originally please try once more.
    • If you are unable to create a log please provide detailed information about your installed Windows Operating System including the Version, Edition and if it is a 32bit or a 64bit system.

***************************************************

We need to see some information about what is happening in your machine. Please perform the following scan again:

  • Download DDS by sUBs from one of the following links if you no longer have it available. Save it to your desktop.
  • Double click on the DDS icon, allow it to run.
  • A small box will open, with an explanation about the tool. No input is needed, the scan is running.
  • Notepad will open with the results.
  • Follow the instructions that pop up for posting the results.
  • Close the program window, and delete the program from your desktop.
Please note: You may have to disable any script protection running if the scan fails to run. After downloading the tool, disconnect from the internet and disable all antivirus protection. Run the scan, enable your A/V and reconnect to the internet.

Information on A/V control HERE


We also need a new log from the GMER anti-rootkit Scanner.

Please note that if you are running a 64-bit version of Windows you will not be able to run GMER and you may skip this step.

Please first disable any CD emulation programs using the steps found in this topic:

Why we request you disable CD Emulation when receiving Malware Removal Advice


Then create another GMER log and post it as an attachment to the reply where you post your new DDS log. Instructions on how to properly create a GMER log can be found here:

How to create a GMER log


As I am just a silly little program running on the BleepingComputer.com servers, please do not send me private messages as I do not know how to read and reply to them! Thanks!
