One of the computers at my house was running slow.
I pulled up the task manager, and the CPU was running at 100%.
In processes, there was a file called "ping.exe" taking up a good deal of the memory usage.
After talking to some friends, I was recommended to run TDSSKiller and combofix.
TDSSKiller did not find anything.
Combofix did find rootkit.zeroaccess!
I still cannot connect to the internet, and the CPU is still running high while idle.
Any help would be greatly appreciated!!!
Thanks!

Hello and welcome to Bleeping Computer!

I am HelpBot: an automated program designed to help the Bleeping Computer Staff better assist you! This message contains very important information, so please read through all of it before doing anything.

We apologize for the delay in responding to your request for help. Here at Bleeping Computer we get overwhelmed at times, and we are trying our best to keep up. Please note that your topic was not intentionally overlooked. Our mission is to help everyone in need, but sometimes it takes just a little longer to get to every request for help. No one is ignored here.

To help Bleeping Computer better assist you please perform the following steps:

***************************************************

Posted Image In order to continue receiving help at BleepingComputer.com, YOU MUST tell me if you still need help or if your issue has already been resolved on your own or through another resource! To tell me this, please click on the following link and follow the instructions there.

CLICK THIS LINK >>> http://www.bleepingcomputer.com/logreply/430869 <<< CLICK THIS LINK



If you no longer need help, then all you needed to do was the previous instructions of telling me so. You can skip the rest of this post. If you do need help please continue with Step 2 below.

***************************************************

Posted Image If you still need help, I would like you to post a Reply to this topic (click the "Add Reply" button in the lower right hand of this page). In that reply, please include the following information:

  • If you have not done so already, include a clear description of the problems you're having, along with any steps you may have performed so far.
  • A new DDS and GMER log. For your convenience, you will find the instructions for generating these logs repeated at the bottom of this post.
    • Please do this even if you have previously posted logs for us.
    • If you were unable to produce the logs originally please try once more.
    • If you are unable to create a log please provide detailed information about your installed Windows Operating System including the Version, Edition and if it is a 32bit or a 64bit system.
    • If you are unsure about any of these characteristics just post what you can and we will guide you.
  • Please tell us if you have your original Windows CD/DVD available.
  • Upon completing the above steps and posting a reply, another staff member will review your topic and do their best to resolve your issues.

Thank you for your patience, and again sorry for the delay.

***************************************************

We need to see some information about what is happening in your machine. Please perform the following scan again:

  • Download DDS by sUBs from one of the following links if you no longer have it available. Save it to your desktop.
  • Double click on the DDS icon, allow it to run.
  • A small box will open, with an explanation about the tool. No input is needed, the scan is running.
  • Notepad will open with the results.
  • Follow the instructions that pop up for posting the results.
  • Close the program window, and delete the program from your desktop.
Please note: You may have to disable any script protection running if the scan fails to run. After downloading the tool, disconnect from the internet and disable all antivirus protection. Run the scan, enable your A/V and reconnect to the internet.

Information on A/V control HERE


We also need a new log from the GMER anti-rootkit Scanner.

Please note that if you are running a 64-bit version of Windows you will not be able to run GMER and you may skip this step.

Please first disable any CD emulation programs using the steps found in this topic:

Why we request you disable CD Emulation when receiving Malware Removal Advice


Then create another GMER log and post it as an attachment to the reply where you post your new DDS log. Instructions on how to properly create a GMER log can be found here:

How to create a GMER log


As I am just a silly little program running on the BleepingComputer.com servers, please do not send me private messages as I do not know how to read and reply to them! Thanks!

I am still in need of help.
The computer has been off since I ran the logs so they are up to date.

That's coming back without any problems so please run Combofix next

Please download ComboFix from one of these locations:* IMPORTANT !!! Save ComboFix.exe to your Desktop making sure you rename it comfix.exe
  • Disable your AntiVirus and AntiSpyware applications including Firewalls, usually via a right click on the System Tray icon. They may otherwise interfere with our tools. (Click on this link to see a list of programs that should be disabled. The list is not all inclusive.)
  • Double click on Comfix.exe & follow the prompts.
  • As part of it's process, ComboFix will check to see if the Microsoft Windows Recovery Console is installed. With malware infections being as they are today, it's strongly recommended to have this pre-installed on your machine before doing any malware removal. It will allow you to boot up into a special recovery/repair mode that will allow us to more easily help you should your computer have a problem after an attempted removal of malware.
  • Follow the prompts to allow ComboFix to download and install the Microsoft Windows Recovery Console, and when prompted, agree to the End-User License Agreement to install the Microsoft Windows Recovery Console.
**Please note: If the Microsoft Windows Recovery Console is already installed, ComboFix will continue it's malware removal procedures.

Once the Microsoft Windows Recovery Console is installed using ComboFix, you should see the following message:

Click on Yes, to continue scanning for malware.

When finished, it shall produce a log for you. Please include the C:\ComboFix.txt in your next reply.

There could still be problems then. You say that Combofix found ZeroAccess, how did Combofix inform you of the presence of ZeroAccess?


Please run FixTDSS

I would like you to run this tool for me - fixTDSS

Download it to your desktop and start the program

Follow the prompts and OK any security prompts

When it is complete it will say the infection was cleared or no infection was found - let me know what it says

I ran the program.
Before rebooting the system, I received a message:
"Access violation at address 00423B70 in module 'ComcastAntispy.exe.' Write of address 0000000D."
The computer restarted and ran the program.
The message stated " Backdoor.Tidserv has not been found on your computer."
And that was it.

I really appreciate all the help!
