ComboFix successfully removed my Google Redirect bug, however, I now get the following popup upon starting my computer:

C:\ProgramData\DirectxTrayBackup.dll

ComboFix hung up during the final phase and did not process a log. I had disabled McAfee prior to running the scan, however, it became enabled again during the automatic reboot which may have prevented the log completion. I no longer have the redirect issue, however, am concerned about the missing DLL file.

Any suggestions on how to restore it?

Thank you.

Hello,

Please follow the instructions in ==>This Guide<== starting at step 6. If you cannot complete a step, skip it and continue.

Once the proper logs are created, then post them in a reply to this topic by using the Add Reply button.

If you can produce at least some of the logs, then please create the post and explain what happens when you try to create the log(s) that you couldn't get. If you cannot produce any of the logs, then still post the reply and explain that you followed the Prep. Guide, were unable to create the logs, and describe what happens when you try to create the logs.

Please note that I am not a member of the Malware Removal Team and will not be assisting you in removing the infection. I'm simply helping you to post the information they need in order to assist you.

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/418568 <<< 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!

Thanks for reopening my post. Just to recap: After running ComboFix to remove my Google Redirect bug, I now get the a popup on starting my computer, as follows:

C:\ProgramData\DirectxTrayBackup.dll

My system hung up during the final phase of ComboFix and did not process a log. I had disabled McAfee prior to running the scan, however, it became enabled again during the automatic reboot which may have prevented the log completion. I no longer have the redirect issue, however, am concerned about the missing DLL file.


I ran the DDS.scr as you suggested and attached the two resulting logs.

Thanks again for your help!

There is a registry entry trying to run this Vundo malware file, but it's long-gone.

To find it we can use SystemLook

Please download SystemLook from one of the links below and save it to your Desktop.
Download Mirror #1
Download Mirror #2

  • Double-click SystemLook.exe to run it.
  • Copy the content of the following codebox into the main textfield:
    :regfind
    DirectxTrayBackup
    
  • Click the Look button to start the scan.
  • When finished, a notepad window will open with the results of the scan. Please post this log in your next reply.
Note: The log can also be found on your Desktop entitled SystemLook.txt

Hi,

I have not had a reply from you for 3 days. Can you please tell me if you still need help with your computer as I am unable to help other members with their problems while I have your topic still open. The time taken between posts can also change the situation with your PC making it more difficult to help you.

If you like you can PM me.

Thanks,


m0le

3/ In the Run dialog box type: regedit

4/ The Windows registry Editor will now open

5/ Click the File option on the main toolbar and, from the drop down menu, select Export

7/ Now name the file

8/ Finally click the Save button

9/ To return the registry back to its original state should something go wrong simply click on the File option on the main registry editor toolbar and then select Import

Open notepad. Please copy the contents of the code box below. To do this highlight the contents of the box and right click on it. Paste this into the open notepad. Save it to your desktop (click file, save as) as fixit.reg In the same open notepad, in the line below select Any for File Type.
