I'm having a really tough time trying to get rid of a Trojan (I think that's what it is). At first my Kaspersky found a trojan that wanted to load from a website, which I blocked when asked if that is the action I wanted to take. This was last night. I blocked it, but soon afterward found that Internet Explorer would load automatically without any toolbars, and most importantly--> automatically. I use Foxfire so IE shouldn't be opening. It would load to an ad site (without toolbars or anything). I looked at Kaspersky's report to see if what I had blocked previously was doing this, and found this entry --> rundll32.exe "C:\Windows\system32\kiherana.dll and also two other entries, identical except for the dll part which were fugisode.dll and yawafuku.dll. I went to my windows\system32 file and renamed the dll's to see what would happen. IE stopped loading as often but would still come up. So I went to the registry to see what was going on (Kaspersky had written out the registry key as well). Here's were it gets interesting (so to speak).

I found rundll32.exe "C:\Windows\System32\kihevana.dll",b
rundll32.exe "C:\Windows\System32\fugisode.dll",a
and rundll32.exe "C:\Windows\System32\yawafuku.dll",s in the HKLM Software\Microsoft\Windows\CurrentVerion\Run section of the registry.

I could easily delete the first two, but the third one would come back instantly, I mean the second I'd hit refresh there it would be again. I would close the registry and reopen it and there it would be again. I tried to download and run malwarebytes, but it won't run. I wouldn't even install until I was in safemode, and it wouldn't run in safe mode, or normal boot.

Then I did a critical scan using Kaspersky, and it finally got rid of the registry entry for the yawafuku.dll, but now I'm getting some new funky stuff going on.
When the computer boot I get this message for anything that wants to load, and after the computer loads, for any program or window I want to open. "The applicationj of DLL globalroot\systemroot\system32\UACliqvqls.dll is not a valid Windows image. Please check this against your installation diskette." and I get the same message, right after the above only for UACviwchris.dll. As if that wasn't enought, my Ad-Watch Event Log is going crazy with Registry modification detected warnings. It's been about half an hour and I already have over 8,000 modifications detected but they are the same four over and over. Here they are:
Root: HKEY_LOCAL_MACHINE
Key: Software\Microsoft\Windows\CurrentVersion\Run
Value: cc528e63
Data:
New Data: rundll32.exe "C:\WINDOWS\System32\pagapobo.dll",b


Root: HKEY_LOCAL_MACHINE
Key: Software\Microsoft\Windows\CurrentVersion\Run
Value: CPMcf61bdff
Data:
New Data: rundll32.exe "C:\WINDOWS\System32\vunogenu.dll",a

Root: HKEY_LOCAL_MACHINE
Key: Software\Microsoft\Windows\CurrentVersion\ShellServiceObjectDelayLoad
Value: SSODL
Data:
New Data: {EC43E3FD-5C60-46a6-97D7-E0B85DBDD6C4}


and it seems my old friend from yesterday is back, too
Root: HKEY_LOCAL_MACHINE
Key: Software\Microsoft\Windows\CurrentVersion\Run
Value: jimefufiki
Data:
New Data: rundll32.exe "C:\WINDOWS\System32\yawufaku.dll",s

Please Help!! I am not exactly a newbie, but I am not that savvy either. How can I get rid of this junk once and for all??? Any help is VERY appreciated.

Thanks,
Diana

Thanks for understanding :thumbsup:

Hello.

Vundos can be very difficult to remove sometimes. We will start off with MBAM and see how much it can remove for us :thumbsup:

Download and run MalwareBytes Anti-Malware

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2
  • Make sure you are connected to the Internet.
  • Double-click on Download_mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
  • MBAM will automatically start and you will be asked to update the program before performing a scan. If an update is found, the program will automatically update itself. Press the OK button to close that box and continue. If you encounter any problems while downloading the updates, manually download them from here and just double-click on mbam-rules.exe to install.
  • On the Scanner tab:
    • Make sure the "Perform Quick Scan" option is selected.
    • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
  • Back at the main Scanner screen, click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad and you may be prompted to restart your computer. (see Note below)
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply and exit MBAM.
Note: If MBAM encounters a file that is difficult to remove, you will be presented with 1 of 2 prompts. Click OK to either and let MBAM proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot will prevent MBAM from removing all the malware.

For complete or visual instructions on installing and running Malwarebytes Anti-Malware please read this link

Thanks again for helping...

I think we've got our first problem, namely Malwarebytes won't start. I had to change it's name to get it to start the install, and once it installs I get to the check for updates and launch screen, and when I click next nothing happens. So what next? Also, I ran Kaspersky again while waiting for a response and it found this:
Trojan Packed.Win32.Tdss.c in C:\Windows\system32\UACdwnppqko.log
\uacinit.dll
\UACjnagkrvw.dll
\UACultieuwu.dll
\UACviwchris.dll
\UACwcbbxasw.dat
and last but not least \UACyliqvqls.dll

It says it will delete them when the computer is restarted. Should I do that, or should I hold off. I don't want to make IT angry and have it blow up my system. Seriously, this thing is really working my last nerve!

Hello.

It seems it's not just the Vundo infection but also the famous TDSSserv Rootkit. Rootkits are very nasty. Take a read below and let me know what you decide to do. If you want to continue let me know.

Posted ImageRootkit Threat

Unfortunatly One or more of the identified infections is a Rootkit/backdoor trojan.

IMPORTANT NOTE: Rootkits and backdoor Trojans are very dangerous because they use advanced techniques (backdoors) as a means of accessing a computer system that bypasses security mechanisms and steal sensitive information which they send back to the hacker. Many rootkits can hook into the Windows 32-bit kernel, and patch several APIs to hide new registry keys and files they install. Remote attackers use backdoor Trojans and rootkits as part of an exploit to gain unauthorized access to a computer and take control of it without your knowledge.

If your computer was used for online banking, has credit card information or other sensitive data on it, you should immediately disconnect from the Internet until your system is cleaned. All passwords should be changed immediately to include those used for banking, email, eBay, paypal and online forums. You should consider them to be compromised. You should change each password by using a different computer and not the infected one. If not, an attacker may get the new passwords and transaction information. If using a router, you need to reset it with a strong logon/password so the malware cannot gain control before connect again. Banking and credit card institutions should be notified of the possible security breach. Because your computer was compromised please read How Do I Handle Possible Identify Theft, Internet Fraud and CC Fraud?

Although the rootkit has been identified and may be removed, your PC has likely been compromised and there is no way to be sure the computer can ever be trusted again. It is dangerous and incorrect to assume that because this malware has been removed the computer is now secure. In some instances an infection may have caused so much damage to your system that it cannot be completely cleaned or repaired. The malware may leave so many remnants behind that security tools cannot find them. Many experts in the security community believe that once infected with this type of malware, the best course of action is to wipe the drive clean, reformat and reinstall the OS. Please read:Should you decide not to follow that advice, we will do our best to help clean the computer of any infections but we cannot guarantee it to be trustworthy or that the removal will be successful. Tell me what you want to do.

Extremeboy

This is bad. I will eventually have to reformat, but I looked online at the list of virus encyclopedia from the link you gave me, and only 2 could find this trojan. For the time being, I think I should try and get rid of it. Then I'll reformat at a later date, since now isn't a very good time. What is the next step?

Hello.

Our next step would be to redirect you to the HJT-Malware Removal forum as rootkits are not that easy to deal with and even if it's removed we cannot guarante that your computer is clean. To make sure it's clean it would be better if you start a topic in that forum. As I told you in that previous post DISCONNECT from the INTERNET. Your compter may be compromised now.

Hello.

@dalvin noob

unlocker1.8.7 is indeed a tool that can be used to remove some files that cannot be deleted normally. However, this tool will definately not work on malware files espically files that have a driver loaded and installed into Windows. Even if it was to remove it, it will come back easily on the next reboot or something.

@Andia

I'm sure one of the HJT Team members will help you out soon. It may take us a while as we have more than 600 logs and some have been waiting for almost 2 weeks!

I hope you understand. Thanks :thumbsup:
