idenitified infection unable to remove

Hi all,

I have been through the steps located in these forums. Spybot reports an infection Win32.Agent.pz but it's not able to remove it as even though it says successful remove, it keeps appearing on each and every scan including after reboot. I have also tried using counterspy, spyware doctor, SDFix, MalwareBytes Anti-Malware, Super Anti-Spyware, McAfee, AVG, BitDefender and Kaspersky however i still have an infection.

This link:

shows a report and I believe this is the exact infection that I have since. twex.exe has been identified by kaspersky not as a virus but placed in "Low Restricted" group of items. My Kaspersky firewall is collecting data attempting to be sent to 195.2.252.140. I have the registry key[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon] infected with the twex.exe name which I have manually removed the twex.exe part but not re-checked for presence. I also have the %system%\twain32 and localservice\twain32 presence. AVG also reported the %system%\twain32 in the rookit scan however, doesn't seem to have removed it.

I have used the sysinternals filemon application and determined that svchost is locking the %system\twain32 files local.ds etc. and therefore I believe that svchost is infected, svchost is also mentioned in the attached report.

I have combofix installed on the computer not presence of trend micro hijack this. The logs seem to help identify infection but I think i've done that. My guess is with the right script and the information in the report I can clean up the system with combofix. Please advise.

What should be the next step? At present I am connecting to the internet with another computer in the home since when I connect infected computer, it downloads other malware from the net (presumably from 195.2.252.140).

Thanks in advance.

Please follow the instructions in the READ & RUN ME FIRST link given further down and attach the requested logs when you finish these instructions.

• If you have problems where no tools seem to run, please try following the steps given in the below and then continue on no matter what you find. You only need to try the TDSSserv steps if having problems getting scans in the Read & Run Me First.
  • TDSSserv Non-Plug & Play Driver Disable
• If something does not run, write down the info to explain to us later but keep on going.
• Do not assume that because one step does not work that they all will not.

READ & RUN ME FIRST. Malware Removal Guide


Helpful Notes:

1. If you run into problems trying to run the READ & RUN ME or any of the scans in normal boot mode. You can run steps in safe boot mode but make sure you tell us what you did later when you post logs. See the below if you do not know how to boot in safe mode:
   
   • Starting your computer in Safe mode
2. If you have problems downloading on the problem PC, download the tools and the manual updates for SUPERAntiSpyware, Malwarebytes and Spybot ( links are given in the READ & RUN ME) onto another PC and then burn to a CD. Then copy them to the problem PC. You will have to skip getting updates if (and only if) your internet connection does not work. Yes you could use a flash drive too but flash drives are writeable and infections can spread to them.
3. To avoid additional delay in getting a response, it is advised that after completing the READ & RUN ME you also read this sticky:
   • Don't Bump! It Only Hurts You!
4. Any additional post is a bump which will add more delay. Once you attach the logs, your thread will be in the work queue and as stated our system works the oldest threads FIRST.
