Hi,

I just downloaded HijackThis and came up with a log that I was going to post here, but then I started wondering if I might actually have another option. A little background info, first:

I bought a new computer a couple months ago, and (probably) through my own doing managed to infect it with a host of viruses, trojans, and miscellaneous spywares. I've spent the last week or so trying different things and different virus scanners in order to clean it up. Smitfraud and Virtumonde seem to have been the primary culprits, but I think I finally managed to get both of them quarantined and/or deleted. However, the pop-ups are still appearing, and I'm still unable to get my Automatic Updates. I had been running Avast before, but it was TrendMicro's Internet Security that finally nailed the "Vundo" trojan this evening. For a short time, I got my Automatic Updates to turn back on, but they stopped after I restarted the computer (even though subsequent system scans come up clean). So, now I'm realizing the full extent of the damage that appears to have already been done, and I'm thinking my best bet might be to just start fresh. Can I be assured that reformatting my hard drive and reinstalling XP will get rid of everything Virtumonde might use to reappear? Do you know if this particular virus is capable of something as sneaky as preventing certain sectors of the hard drive from being formatted in order to survive? Or is there any other way it could still hide, either in the registry, or in any of my data files, or somewhere I simply wouldn't be able to erase it completely? FYI, I know my one hard drive (there are two) has a partition on it that was intended to be used with a Vista recovery disc (the original OS), but I don't know if that might be a factor or not. If it's a sure thing, I'm desperate enough at this point that starting back at square one is getting more and more appealing to me. What do you think?

I sincerely appreciate whatever assistance or advice you can provide.

--Dave

Let's take a look with Malwarebytes...

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 Full 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.

-- 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.

Thank you rigel!!! I think that might've done the trick, because my Automatic Updates are working properly now. My scan log is included below. What do you think about me doing a clean re-install of XP? A waste of time, or a reasonable precaution for the paranoid? And if I have system backups on an external hard drive, am I in danger of reinfecting my computer just by plugging it in?

Again, thanks so much for your time.

Welcome back Dave :thumbsup:

A clean reinstall is an option. You will find that we will even recommend a reformat in certain cases. At this point, I think you will be fine, but it may be too early to tell.

You have a couple of items shown like this:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\LSA\Authentication Packages (Trojan.Vundo.H) -> Data: c:\windows\system32\opnkljig -> Delete on reboot.

Be sure to reboot immediately after your scan to remove the harder malware items.

Please update and rerun Malwarebytes and post a new log. Next...
