Yeah I'm having the same issue and have been battling it for 1 whole day now. I had a couple others that Norton found, but for Trojan.Zeroaccess!inf4, Norton tools do nothing except detect it.

I ran all of the tools and made a boot disk which found it but failed to fix it.

Any help by Norton or anyone else would be great. This one is a pain in the buttocks.

Re: Trojan.Zeroaccess!inf4 Infection in Services.exe. Help!

A good way to start would be downloading TDSS killer for Kaspersky.

Oh, you want to download MBRcheck.exe to check your Master Boot Record.http://majorgeeks.com/MBRCheck_d7076.html

If you could turn off your computer then when you press the power button keep hitting F8, then when a screen appears (Safe mode etc) Go into 'Repair Your Computer', log in then go into Command Prompt, then punch in Bootrec /fixmbr

This will make Windows write a new MBR to the system.

Proceed with a full scan in safe mode with Norton.

I also recommend you to download GMER, to find where the rootkit is. http://www.gmer.net/

This user has no idea what they are doing at all, and they can't read the info provided, a dangerous user.

This Zeroaccess has nothing to do with the Boot Sector, and if you also have Pihar (unknown if so) using the tool, will more than likely cause Windows to not boot.

As for TDSSkiller, with this zeroaccess, it doesn't work with this variant, as users who have come here after using TDSSkiller have found out, when I notice in the FRST log TDSSkiller, FixZeroaccess and NPE have all been used.

Quads, thanks for the response. I have not done what the previous poster said I should try. I was hoping that you would see my post and help me remove this from my laptop. I trust that your fix is the proper way to do so. Could you help me out and get this removed? Thank you.

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 )

  • 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.

I am not touching your system, you have used advanced programs against warnings in this thread, and still gone on your own.

Re: Trojan.Zeroaccess!inf4 Infection in Services.exe. Help!

I did not see any warnings against advanced programs. At any rate I found another helper on a different forum who walked me through a procedure using otl and ComboFix. He was able to help me.

I really think it strange that I'm paying for Norton to protect me from these viruses. Norton is unable toto block me from this infection . Is unable to remove the infection using any of its tools lthat it povides. and that it relies on volunteers like you to resolve my problems. I doubt that McAfee or anybody else is any better so I'm sticking with Norton .I'm pretty sure they protected me from any permanent damage or loss of files so at least that's something .

Step 3. 

Please read carefully Read all of this message first

Download Combofix http://www.bleepingcomputer.com/download/anti-virus/combofix  It will be a new copy as it always gets updated.


  • 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)

step 4. (a)

Please read carefully and Slowly

You might have to export the results

 

 Please scan with ESET next 


I'd like us to scan your machine with ESET OnlineScan

  • Hold down Control and click on the following link to open ESET OnlineScan in a new window.
    ESET OnlineScan
  • Click the  button.
  • For alternate browsers only: (Microsoft Internet Explorer users can skip these steps)
    • Click on  to download the ESET Smart Installer. Save it to your desktop.
    • Double click on the  icon on your desktop.
  • Check 
  • Click the  button.
  • Accept any security warnings from your browser.
  • Under scan settings, check  and DON'T (NO) check Remove found threats (reason for this is we don't want something deleted and then Windows won't load).
  • Click Advanced settings and select the following:
    • Scan potentially unwanted applications
    • Scan for potentially unsafe applications
    • Enable Anti-Stealth technology
  • ESET will then download updates for itself, install itself, and begin scanning your computer. Please be patient as this can take some time.

Re: Trojan.Zeroaccess!inf4 Infection in Services.exe. Help!

Disable Norton

Start OTL again but this time click the Black CleanUp button, then make sure the C:\_OTL folder is deleted.

After that you are free to go on your merry way.  You are now fixed / Solved.

If you want Malwarebytes download the Free version to install and don't click the Trial button

If you want to, you can turn off System Restore wait for it to clear the Restore Points and then Turn it back on once you find all is happy. today, tomorrow whenever.

 

Stick with just scanning with Norton and MBAM Free

I am not touching your system,  you went against instructions and warnings, or cannot read instructions, then also  did not run the tool(s) correctly.

No one told you to run the tools and to search.

Do what you like you have already done things on your own run tools like you know what you are doing, ignored warnings, instructions, run tools incorrectly so can't even follow steps. (but you know what you are doing) 

I give the warnings on earch thread for others to see and I have checked they are on this thread also (page 1)
