Cannot remove ZeroAccess Trojan


Recommended Posts

Dear MBAM forum,

I caught the hateful ZeroAccess Trojan, with the 000000cb.@ and 0000008.@ components. As Iearned from Ad-Aware, my services.exe is also infected.

I bet this sounds pretty familiar already :). As MBAM and Ad-Aware couldn't remove this pest and I'm a bit hesitant using programs like ComboFix on my own, I'd like to ask you guys for help.

I attached the DDS files, as well as my latest MBAM-log.

In advance, thank you for your time and help.

Gladiolis.

Welcome to the forum.

Please remove any usb or external drives from the computer before you run this scan!

Please download and run RogueKiller to your desktop.

Quit all running programs.

For Windows XP, double-click to start.

For Vista or Windows 7, do a right-click on the program, select Run as Administrator to start, & when prompted Allow to run.

Click Scan to scan the system.

When the scan completes > Close out the program > Don't Fix anything!

Don't run any other options, they're not all bad!!!!!!!

Post back the report which should be located on your desktop.

Please read the following information first.

You're infected with Rootkit.ZeroAccess, a BackDoor Trojan.

BACKDOOR WARNING

------------------------------

One or more of the identified infections is known to use a backdoor.

This allows hackers to remotely control your computer, steal critical system information and download and execute files.

I would advice you to disconnect this PC from the Internet immediately. If you do any banking or other financial transactions on the PC or if it should contain any other sensitive information, please get to a known clean computer and change all passwords where applicable, and it would be wise to contact those same financial institutions to apprise them of your situation.

Though the infection has been identified and because of it's backdoor functionality, your PC is very likely compromised and there is no way to be sure your computer can ever again be trusted. Many experts in the security community believe that once infected with this type of trojan, the best course of action would be a reformat and reinstall of the OS. Please read these for more information:

I will try my best to clean this machine but I can't guarantee that it will be 100% secure afterwards.

Let me know what you decide to do. If you decide to go through with the cleanup, please proceed with the following steps.

-----------------------------------------

Run RogueKiller again and click Scan

When the scan completes > click on the Files tab

Put a check next to all of these and uncheck the rest: (if found)

[ZeroAccess][FILE] @ : C:\Windows\Installer\{80aa28bd-953b-0d79-ac52-59b01480de54}\@ --> gevonden

[ZeroAccess][FOLDER] U : C:\Windows\Installer\{80aa28bd-953b-0d79-ac52-59b01480de54}\U --> gevonden

[ZeroAccess][FOLDER] L : C:\Windows\Installer\{80aa28bd-953b-0d79-ac52-59b01480de54}\L --> gevonden

[ZeroAccess][FILE] Desktop.ini : C:\Windows\Assembly\GAC_32\Desktop.ini --> gevonden

[ZeroAccess][FILE] Desktop.ini : C:\Windows\Assembly\GAC_64\Desktop.ini --> gevo

Now click Delete on the right hand column under Options

~~~~~~~~~~~~~~~~~~~~~~~~~~~

Next...........

Please create a new system restore point before running Malwarebytes Anti-Rootkit if you can.

MBAR tutorial

Download Malwarebytes Anti-Rootkit from HERE

  • Unzip the contents to a folder in a convenient location.
  • Open the folder where the contents were unzipped and run mbar.exe
  • Follow the instructions in the wizard to update and allow the program to scan your computer for threats.
  • Click on the Cleanup button to remove any threats and reboot if prompted to do so.
  • Wait while the system shuts down and the cleanup process is performed.
  • Perform another scan with Malwarebytes Anti-Rootkit to verify that no threats remain. If they do, then click Cleanup once more and repeat the process.
  • When done, please post the two logs produced they will be in the MBAR folder..... mbar-log.txt and system-log.txt

To attach a log if needed:

If no additional threats were found, verify that your system is now running normally, making sure that the following items are functional:

Internet access

Windows Update

Windows Firewall

If there are additional problems with your system, such as any of those listed above or other system issues, then run the fixdamage tool included with Malwarebytes Anti-Rootkit and reboot.

Verify that your system is now functioning normally.

Ok, Roguekiller and MBAR wiped out the Trojan, awesome! Thank you very much!

Logs attached as asked.

I found that my internet activity was restored to normal. No long waiting times for password-driven sites and everything returned to normal.

However, I indeed have troubles with Windows Update, Firewall and some other services in this department. I can't seem to start them. When I try to start them manually via services.msc, I get some errors (0x6d9 in case of the Firewall). WU and the Firewall seem to be disabled. Any ideas by any chance?

Thanks for the great help so far!

Well Done, lets run ComboFix to clear up any leftovers.

Please download and run ComboFix.

The most important things to remember when running it is to disable all your malware programs and run Combofix from your desktop.

Please visit this webpage for download links, and instructions for running ComboFix

http://www.bleepingcomputer.com/combofix/how-to-use-combofix

Ensure you have disabled all anti virus and anti malware programs so they do not interfere with the running of ComboFix.

Information on disabling your malware programs can be found Here.

Make sure you run ComboFix from your desktop.

Give it at least 30-45 minutes to finish if needed.

Please include the C:\ComboFix.txt in your next reply for further review.

---------->NOTE<----------

If you get the message Illegal operation attempted on registry key that has been marked for deletion after you run ComboFix....please reboot the computer, this should resolve the problem. You may have to do this several times if needed.
