Trojan.Zeroaccess!Inf in Services.exe: How to remove?

[ Edited ]

Hi,

 

As many others I do have a persistent Trojan on my laptop: Trojan.Zeroaccess!Inf in services.exe

It was identified by Norton 360 a few days ago.

Tried the Norton Power Eraser and the suggested Removal Tool without success.

 

My system:

HP Elitebook 8530w

Windows Vista Buisness 32-bit, Service Pack 2

 

Any help to remove this is highly appreciated.

 

Thanks,

Mark

Re: Trojan.Zeroaccess!Inf in Services.exe: How to remove?

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.

 

Unfortunately, with the amount of threads means the waiting time is longer, Norton continually Blocking files won't hurt your system but is is just annoying, Please wait and be patient.   I am  trying to keep up, spending hours here to script and clean machines on a first come/first served basis. If you or someone adds to your thread It will be pushed back in line due to the new update.  I use the boards in reverse to what is seen

 

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.

Please read carefully and follow these steps.


Download TDSSKiller from http://support.kaspersky.com/faq/?qid=208280684  click on the TDSSkiller.exe green link.

 

Double click on TDSSKiller.exe to run the application,

Open the Change Parameters option and select the detect TDL File system

Click OK

 

Then on Start Scan.


If an infected file is detected, the default action will be Cure, click on Continue.
If a suspicious file is detected, the default action will be Skip, click on Continue.

 

Look for the Filesystem detection

It may ask you to reboot the computer to complete the process. Click on Reboot Now.


If no reboot is require, click on Report. A log file should appear. Please copy and paste into Notepad and attach back here.
If a reboot is required, the report can also be found in your root directory, (usually C:\ ) in the form of "TDSSKiller.[Version]_[Date]_[Time]_log.txt". Please attach the log in the post back.

Re: Trojan.Zeroaccess!Inf in Services.exe: How to remove?

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)

Re: Trojan.Zeroaccess!Inf in Services.exe: How to remove?

Download the attached .txt file, and remove the .txt extension so that you have the files end in .reg 

 

Then click to run the files and then the system should ask if you want the data added to the registry, answer = yes.  A cofirmation message should them appear saying that the data has been added..

 

The other way is to right click the files and choose "Open With" from the menu, and you should see Registry Editor as an option to choose.

 

Once added restart the system and run FSS with all options again.

2 services still don't want to start,  lets make sure they are correct

 

Download the attached .txt file, and remove the .txt extension so that you have the files end in .reg 

 

Then click to run the files and then the system should ask if you want the data added to the registry, answer = yes.  A cofirmation message should them appear saying that the data has been added..
