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

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.

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 :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.

 

 

Do you have a Flash Drive??
