Hi all,

So I've been fighting a nasty infection, here's a link to the original topic--pretty much just the basics rkill + MBAM. I have a vista home basic.

Below and attached are my DDS logs. I tried a GMER scan but the first time I left the computer to scan it "shut down unexpectedly"...and of course once this computer restarts the infection pops back up again (I suppress it with rkill) and it's nearly impossible to run rkill again since the virus seems to shut it down/interfere with it. The second time I tried GMER (without even running rkill which is impossible atm) the screen froze and I'm willing to bet it would have shut down again.

Sorry I couldn't c+p...I can't open notepad right now, so I had to attach both files. Hope it's not too much trouble--this computer's basically nonfunctional right now.

Thanks so much for all your help,
nsweeney

I'm all ears, and thanks so much. Since my last post I managed to run rkill again so the computer is functional as long as it stays on constantly. I haven't tried to run GMER again though because the first two times it froze/shutdown the computer. Let me know what I can do, and again thank you smile.gif

Let's see if we can get a scan which covers rootkits

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.

Sorry for the delay, you caught me during exam week smile.gif

Here's the GMER log--I'm pretty sure the whole thing scanned but the computer froze/stalled afterwards and had to be rebooted. The log saved successfully.

Nothing so far. Virtumonde is usually easy to identify and I haven't seen any signs, so that's good. smile.gif

Let's run MBAM which targets the infection to look for any remnants.

Please download Malwarebytes Anti-Malware and save it to your desktop.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application or, if you are using Vista, right-click and select Run As Administrator 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, they may alert you after scanning with MBAM. Please permit the program to allow the changes.

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

It's looking pretty tidy here.

One more scan, ESET will look for infected files which the tools we have been using wont.

I'd like us to scan your machine with ESET OnlineScan
  1. Hold down Control and click on the following link to open ESET OnlineScan in a new window.
    ESET OnlineScan
  2. Click the button.
  3. For alternate browsers only: (Microsoft Internet Explorer users can skip these steps)
    1. Click on to download the ESET Smart Installer. Save it to your desktop.
    2. Double click on the icon on your desktop.
  4. Check
  5. Click the button.
  6. Accept any security warnings from your browser.
  7. Check
  8. Push the Start button.
  9. ESET will then download updates for itself, install itself, and begin scanning your computer. Please be patient as this can take some time.
  10. When the scan completes, push
  11. Push , and save the file to your desktop using a unique name, such as ESETScan. Include the contents of this report in your next reply.
  12. Push the button.
  13. Push

Hmm, so I am trying to run the scan and the first step in the process keeps saying "Can not get update. Is proxy configured?"

Also, the popups appear to have stopped, though last time I ran MBAM (before this scan) my computer came up clean even though there were still numerous popups. I find it odd that they've simply stopped. Additionally, perhaps I'm just blind but I can't seem to find Internet Explorer (which was where the popups were displaying, so perhaps there's a connection)--I was going to use it to try to run the ESET scan. Also, there seem to be a bunch of newly revealed media programs in the start menu. Maybe they've always been there (this is my mom's computer so I don't spend a lot of time on it)--like Vongo, for instance, which was supposedly pre-installed in '08 HPs--but I find it hard to believe that Cyberlink DVD Suite, and Vongo, and muvee, and Sling Media (and regcure, for that matter, which has an empty folder now) all came with this computer.

Thanks again for your time and patience...the overt threat seems to be gone but I have no idea why.

Are you going to be able to run ESET?

It is entirely possible that the pop-ups could have stopped. Just because MBAM didn't pick up a threat doesn't mean you are necessarily malware-free.

We haven't done a great deal to the PC though but maybe you inadvertently have if you have run any other tools which target Vundo - they all do these days.

ESET would certainyl be a good indicator of what is left, if anything. smile.gif

Let's see if this is a system problem or malware. Attempt an online scan with BitDefender - please use Internet Explorer.

Please run a BitDefender Online Scan
  • Click I Agree to agree to the EULA.
  • Allow the ActiveX control to install when prompted.
  • Click Click here to scan to begin the scan.
  • Please refrain from using the computer until the scan is finished. This might take a while to run, but it is important that nothing else is running while you scan.
  • When the scan is finished, click on Click here to export the scan results.
  • Save the report to your desktop so you can post it in your next reply.

  • Open Control Panel and navigate to "Network and Internet Connections"
  • Then click Network and Internet Connections
  • Now select your active Internet connection and right click on it. Suppose if you are using wireless connection right click on "Wireless Network Connection"
  • Select the TCP/IP service in the list and then click properties
  • Change DNS to "Obtain DNS server automatically

Please now try to run ESET on Firefox
