Hi

My computer with windows 2000, service pack 3 got infected. I am using McAffee antivirus and firewall (current version) + hardware firewall. McAffee was already in use when the infection happened.

It all started with the computer being less and less responsive and I started to get randomly popup windows (sagispul).

I found several instances of Virtumonde trojans (virtumonde.generic, . sci, .prx) and smitfraud. McAffee didn't manage to remove them. I also run Spybot, and Superantispyware. They did clean something and now they run without finding any problem but the computer is still infected. When I turn it on, after some time McAffee antivirus and firewall get shut down. If I run McAffee antivrus it detects 2 problems, but it never finishes scanning (it just gets stuck) so I don't even know what did it detect.

What should I do (before reformatting HD :thumbsup:?

The process of cleaning your computer may require temporarily disabliling some security programs. If you are using SpyBot Search and Destroy, please refer to Note 2 at the bottom of this page.

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 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.
  • 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 may be asked to reboot your computer so it can proceed with the disinfection process. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

Note 2:
-- MBAM may make changes to your registry as part of its disinfection routine. If you're using other security programs that detect registry changes (like Spybot's Teatimer), they may interfere with the fix or alert you after scanning with MBAM. Please disable such programs until disinfection is complete or permit them to allow the changes. To disable these programs, please view this topic: How To Temporarily Disable Your Anti-virus, Firewall And Anti-malware Programs

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

If mbam won't install

Some types of malware will disable MBAM and other security tools. If MBAM will not install, try renaming it. Right-click on the mbam-setup.exe file and change the .exe extension to .bat, .com, .pif, or .scr and then double-click on it to run.

If after installation, MBAM will not run, open the Malwarebytes' Anti-Malware folder in Program Files, right-click on mbam.exe and change the .exe as noted above. Then double-click on it to run.

Thanks for the help.
I run Malwarebytes' Anti-Malware per your instructions and it found 1 problem. Here is the log file:

After clicking remove all, anti-malware said it will be removed after reboot but it didn't reboot. I had to reset the system manually. After that system couldn't boot normaly so I had to boot it in the safe mode. After that I just shut it down and now it boots normaly (but very, very slowly). It seems there are still some problems.

I run anti-malware again, but this time full scan and I got same message as before:

I rebooted computer and it failed to boot. I had to repeat entire procedure with safe mode to be able to boot it normaly

There is a directory c:\a but not file with name a on c:

One more thing, I was looking on C: and I found file avenger.txt that was freshly generated after last boot of the system. It said something like "C:\A is a directory, not file and can not be removed, it needs to be removed manually" This happend in the safe mode so I couldn't copy the file on the memory stick to transfer it to other computer so I can send it. After I finally managed to boot system normally (that by the way took maybe 10 minutes) the file dissappeared so I cannot attach it's content

Have you at any time run an anti-spyware program called the Avenger?
That is where those items are coming from

If yes, uninstall the program and delete the C:\A file
You might have to show hidden files:

Hi,

I don't remember I've ever run program Avenger. I searched hard drive for it and I see directory Avenger but there is nothing inside. If I look at list of processes in Windows task manager, I don't see any process with avenger name, so I am assuming avenger is not running (unless its process has some other name)

I already have set option to see hidden files as you suggested.

I am bit confused by the Anti-Malware report because it is refering to the file c:\A. I don't see any file with name A. There is only a directory C:\A which contains several subdirectories and many files. Vast majority of those are various pdf documents. This directory has more than 1 Gb and I would like to save at least pdf files if I have to delete this directory. Are pdf files safe from viruses and other malware (I am assuming they are).

One more thing. I don't know if it is important but when I run McAfee it usually gets stuck while scanning c:\winnt\system32\dinput8.dll (at least it shows that name).

I am totally stuck. Do you have any good suggestion ow should I proceed?

dinput8.dll dinput.dll is a DirectC DLL, which handles DirectInput. This gives functionality for multimedia input devices such as joysticks.

processlibrary.com

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

C:\A which contains several subdirectories and many files.

That is supposedly a part of the Avenger anti-malware program that I mentioned

I'm going to suggest that you follow the instructions and prepare a HJT log, here:
http://www.bleepingcomputer.com/forums/t/34773/preparation-guide-for-use-before-using-malware-removal-tools-and-requesting-help/
Then post the log in the proper form here:

Our team members are rather busy, so it may take a while to get to you
Be patient and good luck

Hello gallileo,

Now that you have a log posted here: http://www.bleepingcomputer.com/forums/t/194505/trojanvundo-infection/ you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a HJT Team member, nor should you ask for help elsewhere. Doing so can result in system changes which may not show in the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the HJT Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the HJT Team members are EXTREMELY busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the HJT Team. Generally the 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.

If after 5 days you still have received no response, then post a link to your HJT log in the thread titled "Haven't Had A Reply In Five Days?".

To avoid confusion, I am closing this topic. Good luck with your log.

Orange Blossom :thumbsup:
Help us help you. If HelpBot replies, you MUST follow step 1 in its reply so we know you need help.
