Infected XP. Cannot clean (please read on.......)

Friends' PC got infected. Ran Symantec Endpoint and Malwarebytes Anti-Malware which found a lot of infected files, etc. which were all deleted.

The leftover problem (that I know of) is now a registry entry - HKLM\..\Run: [Kradik] rundll32.exe "C:\WINDOWS\Gbubikavup.dat",e

This comes up with a file not found message window on boot up. Deleting the registry entry just makes it come back again immediately. Deleting it in Safe Mode makes it come back when restarting into regular mode. Unselecting it from Startup in MSCONFIG makes it come back.

HijackThis log is attached. Help is greatly appreciated!!!!! (Posted from my PC)

Anybody?

Hello FullScreen57,

While we understand your frustration at having to wait, please note that Bleeping Computer deals with several hundred requests for assistance such as yours on a daily basis. As a result, our backlog is quite large, as are other comparable sites that help others with malware issues. Athough our HJT Team members work on hundreds of requests each day, they are all volunteers who work logs when they can and are able to do so. No one is paid by Bleeping Computer for their assistance to our members.

Further, our malware removal staff is comprised of team members with various levels of skill and expertise to deal with thousands of malware variants, some more complex than others. Although we try to take DDS/HJT logs in order (starting with the oldest), it is often the skill level of the particular helper and sometimes the operating system that dictates which logs get selected first. Some infections are more complicated than others and require a higher skill level to remove. Without that skill level attempted removal could result in disastrous results. In other instances, the helper may not be familiar with the operating system that you are using, since they use another. In either case, you wouldn't want someone to assist you who is not familiar with your issue and attempt to fix it, would you?

We ask that once you have posted your log and are waiting, please DO NOT "bump" your thread or make further replies until it has been responded to by a member of the HJT Team. The reason we ask this or do not respond to your requests is because that would remove you from the active queue that Techs and Staff have access to. The malware staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response, there will be 1 reply. A team member, looking for a new log to work may assume another HJT Team member is already assisting you and not open the thread to respond.

That is why I have made an edit to your last post, instead of a reply. Please do not multiple post here, as that only pushes you further down the queue and causes confusion to the staff.

Please be patient. It may take a while to get a response but your log will be reviewed and answered as soon as possible.

Thank you for understanding.

Regards,

The weatherman

Thanks weatherman. My apologies for the impatience. I will wait for my turn.

Hello and welcome to Bleeping Computer

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.

If you have since resolved the original problem you were having, we would appreciate you letting us know. If not please perform the following steps below so we can have a look at the current condition of your machine.

If you have not done so, include a clear description of the problems you're having, along with any steps you may have performed so far.

Upon completing the steps below another staff member will review and take the steps necessary with you to get your machine back in working order clean and free of malware.

If you have already posted a DDS log, please do so again, as your situation may have changed.
Use the 'Add Reply' and add the new log to this thread.


Thanks and again sorry for the delay.

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

• Download DDS by sUBs from one of the following links. Save it to your desktop.
  • DDS.scr
  • DDS.pif
• Double click on the DDS icon, allow it to run.
• A small box will open, with an explaination 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

Thanks you for the response. I have attached the logs.

Hello FullScreen57 and welcome to Bleeping Computer!!

I will be handling your log to help you get cleaned up. I apologize for the delay but the forum is very busy.

As you can see the logs we ask for are very extensive and take a lot of time to investigate. In addition, since I am still in training all of my responses have to be reviewed by our excellent expert staff so there may be a delay in response time. The advantage is that your log will be evaluated by two sets of eyes and two brains.

If you haven't already, you can keep the link to this topic in your Favorites. Alternatively, you can click the Options button at the top bar of this topic and Track this Topic, where you can choose email notifications.

Please make sure Word Wrap in notepad is turned off when copying and pasting logs and only attach logs if asked to. Do not wrap logs in codebox or code tags. It makes it very difficult to read and analyze them. Please paste them directly into the reply box.

Please do not make any changes to your system until we are through. Fixes are based upon information that is current from your system so any changes can affect our strategy. Please refrain from running any tools we may use without specific instructions.

If your operating system is Windows Vista it may be necessary to right click then choose Run as Administrator any programs we use.

Before we begin please check and follow the instructions on How to show hidden files in Windows Vista and Windows XP

Again, keep in mind that it may take a couple of days before I can reply but once we get started the process should speed up.

Please reply to this post so we will know you still need assistance.

reason for edit: fixed link

Thank you for your patience!!

Hello again FullScreen57,

Step 1.

We need to disable Spybot S&D's "TeaTimer"
TeaTimer works by preventing ANY changes to the system. It will attempt to undo any fixes we run, because it blocks these fixes from running.

In order to safeguard your system from problems that can be brought on by a half finished fix, we need to disable TeaTimer. We can reenable it when we're done if you like.

• Open SpyBot Search and Destroy by going to Start -> All Programs -> Spybot Search and Destroy -> Spybot Search and Destroy.
• If prompted with a legal dialog, accept the warning.
• Click and then on "Advanced Mode"
  
• You may be presented with a warning dialog. If so, press
• Click on
• Click on
• Uncheck this checkbox:
  
• Close/Exit Spybot Search and Destroy

Step 2.

Download Combofix from any of the links below, and save it to your desktop.

Link 1
Link 2

• Close/disable all anti-virus and anti-malware programs so they do not interfere with the running of ComboFix. Refer to this page if you are not sure how.
• Close any open windows, including this one.
• Double click on ComboFix.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.
• If you did not have it installed, you will see the prompt below. Choose YES.
• 
• 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.

Note:The Windows Recovery Console will allow you to boot up into a special recovery (repair) mode. This allows us to more easily help you
should your computer have a problem after an attempted removal of malware. It is a simple procedure that will only take a few moments of your time.

• 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 will produce a report for you. Please post the contents of the log (C:\ComboFix.txt).

Leave your computer alone while ComboFix is running.
ComboFix will restart your computer if malware is found; allow it to do so.

Note: Please Do NOT mouseclick combofix's window while its running because it may cause it to stall.

Step. 3

Please download GMER from one of the following locations and save it to your desktop:

• Main Mirror
  This version will download a randomly named file (Recommended)
• Zipped Mirror
  This version will download a zip file you will need to extract first. If you use this mirror, please extract the zip file to your desktop.

• Disconnect from the Internet and close all running programs.
• Temporarily disable any real-time active protection so your security programs will not conflict with gmer's driver.
• Double-click on the randomly named GMER file (i.e. n7gmo46c.exe) and allow the gmer.sys driver to load if asked.
• Note: If you downloaded the zipped version, extract the file to its own folder such as C:\gmer and then double-click on gmer.exe.
  
  
  
• GMER will open to the Rootkit/Malware tab and perform an automatic quick scan when first run. (do not use the computer while the scan is in progress)
• If you receive a WARNING!!! about rootkit activity and are asked to fully scan your system...click NO.
• Now click the Scan button. If you see a rootkit warning window, click OK.
• When the scan is finished, click the Save... button to save the scan results to your Desktop. Save the file as gmer.log.
• Click the Copy button and paste the results into your next reply.
• Exit GMER and re-enable all active protection when done.

-- If you encounter any problems, try running GMER in Safe Mode.

In your next reply please include:

Combofix.txt
gmer.log
