Problem with Trojan.ZeroAccess.B and Trojan.Gen

Hello! I started a thread because it was specifically written not to follow the steps to other threads with the same problem.

 

Please help me with the following:

Norton Security Suite ( the one provided by Comcast) keeps blocking Trojan.ZeroAccess.B, Trojan.Gen and Trojan.Gen.2 every 2-3 minutes. Also, 2-3 windows stating "Host Process for Windows Services has stopped working" keep popping up every minute.

 

The infected computer is a HP Pavilion a6120n with 32-bit Windows 7 Ultimate (Service Pack 1).

 

I followed the steps given by Norton (NPE) and I deleted any suspicious files that were modified at the time of infection (only the Prefetch and Temp folders were touched).

 

Thank you in advance for your help,

NiNi

ANY other user other than the thread starter is not to use any instructions, scripts or proceedures,  The work though in cleaning a system is individual and only for that system due to a number of factors.

 


 

Please do not run any tools unless instructed to do so. 

  • We ask you to run different tools in a specific order to ensure the malware is completely removed from your machine, and running any additional tools may detect false positives, interfere with our tools, or cause unforeseen damage or system instability. Do as the instructions ask nothing extra or run things twice
  • If I ask a Question just answer it, don't run anything unless it states.
  • Major steps used:

1. Find

2. Break

3. Destroy

4. Cleanup  (including system as a whole)

 

Please read every post completely before doing anything. 

  • Pay special attention to the NOTE: lines, these entries identify an individual issue or important step in the cleanup process.

 

  • Logs from malware removal programs (OTL is one of them) can take some time to analyze. I need you to be patient while I analyze any logs you post. Please remember, I am a volunteer, and I do have a life outside of these forum, (sometimes :smileylol:)

  • Attention to detail is important! Since I cannot see or directly interact with your computer I am dependent on you to "be my eyes" and provide as much information as you can regarding the current state of your computer.

Here is more information about the current state of the computer:

For about 6 hours, Norton kept blocking unauthorized access by services.exe. After I restarted the computer, it blocked Trojan.ZeroAccess again. Windows Security Center is also off. At some point during the night, Norton could not update itself until I used Live Update 5 times.

 

Thank you again,

NiNi

Zeroaccess plays with Windows and AV software

Hello!

The log is attached.

 

Sorry for my late reply. I though I had a subscription then checked and saw otherwise. :)

Step 3. 

 

 

Please read carefully Read all of this message first

 

Download Combofix http://www.bleepingcomputer.com/download/anti-virus/combofix


  • Ensure that Combofix is saved directly to the Desktop <--- Very important  (Not in the Download(s) or Temp folders)

  • Disable all security programs as they will have a negative effect on Combofix, Disabled for say 1 hour or more.
  • Close any open browsers and any other programs you might have running

 

Right click the combofix.exe on the desktop and select from the menu "Run as Administrator"

 

  • If you are using windows XP It might display a pop up saying that "Recovery console is not installed, do you want to install?" Please select yes & let it download the files it needs to do this. Once the recovery console is installed Combofix will then offer to scan for malware. Select continue or yes.
  • When finished, it will produce a report for you. Please post the "C:\ComboFix.txt" for further review


****Note: Do not mouseclick combofix's window while it's running. That may cause it to stall or freeze ****

Note: ComboFix may reset a number of Internet Explorer's settings, including making it the default browser.
Note: Combofix prevents autorun of ALL CDs, floppies and USB devices to assist with malware removal & increase security.

*EXTRA NOTES*

  • If Combofix detects any Rootkit/Bootkit activity on your system it will give a warning and prompt for a reboot, you must allow it to do so.
  • If Combofix reboot's due to a rootkit, the screen may stay black for several minutes on reboot, this is normal
  • If after running Combofix you receive any type of warning message about registry key's being listed for deletion when trying to open certain items, reboot the system and this will fix the issue (Those items will not be deleted)

Hello.

I don't mean to double post but, I just want to say that I won't have access to the computer until Monday morning (time of board).

 

Thanks,

NiNi

No Problem,  

 

Leave the system as is with no changes.

 

Quads

Thank you!
I can access the computer again. To make sure there were no changes to the system, I turned off the computer and disconnected it from the Internet.

Can you find this folder.

 

C:\Qoobox\Quarantine\C\Windows\System32

 

Quads

Yes, I can.

 

NiNi

Norton should be detecting the services.exe.vir inside as it is part of zeroaccess.  So

 

 Disable Norton

 

Delete the System32 folder  inside the QooBox folder.  C:\Qoobox\Quarantine\C\Windows\System32

make sure it is not the working Windows system32 folder.

 

It will then go into your recycle bin, so then empty the Recycle Bin.

 

After Enable Norton.

 

Step 4 (b) to come.

 

Quads 

I completed the steps above and deleted the folder.
