The problems started a few weeks ago when DH used IE instead of Firefox. It seems that whenever IE is used on this computer something bad happens. In any case, after he had used IE, Symantec identified a few viruses, the history report is showing that it is Trojan.Vundo/gen1. Symantec said that it had cleaned the infection, but we were still getting popups. I did the Vundo/Virtumonde protocols as shown here in other links, ran Ad-Aware, etc., and no scans that I ran found anything. But the popups were still there. An invisible browser window would open somewhere and we would hear ads running in the background, mostly for something about making money on Google. We'd also get ads for a supposedly "local" newspaper and a fancy coffee machine.

I was worried about potentially losing important data, so a couple days ago I signed up and backed up all our important files online. While I was waiting for the upload to complete, I think something else or a more virulent strain of Vundo took hold. Today we got all sorts of adult popups along with the fake malware program alerts and such. Ad-Aware was disabled when I tried to run it, then the whole machine froze and I had to power off. Now that I am back on, Ad-Aware is able to run again and is detecting malicious processes, but I'm not quite sure where to go from here.

I've fixed malware problems before on this machine, and have even had to wipe the hard drive once before, so I'm not completely new to this type of problem. But with the disabling of all the fixer programs, I'm just not sure where to start. If someone could give me some direction I would greatly appreciate it.

Thanks in advance,
Megan

ETA: Ad-Aware just finished running and found Win32.Adware.Vitumonde and Win32.Ad\..\umonde/C

Hello and welcome.. We need to try it this way

If enabled we need to disable Spybot S&D's "TeaTimer"
TeaTimer works by preventing ANY changes to the system. It will attempt to undo any fixes we run, because it blocks these fixes from running.

In order to safeguard your system from problems that can be brought on by a half finished fix, we need to disable TeaTimer. We can reenable it when we're done if you like.
  • Open SpyBot Search and Destroy by going to Start -> All Programs -> Spybot Search and Destroy -> Spybot Search and Destroy.
  • If prompted with a legal dialog, accept the warning.
  • Click Posted Image and then on "Advanced Mode"
    Posted Image
  • You may be presented with a warning dialog. If so, press Posted Image
  • Click on Posted Image
  • Click on Posted Image
  • Uncheck this checkbox:
    Posted Image
  • Close/Exit Spybot Search and Destroy
Please download TFC by Old Timer and save it to your desktop.
alternate download linkSave any unsaved work. TFC will close ALL open programs including your browser!
Double-click on TFC.exe to run it. If you are using Vista, right-click on the file and choose Run As Administrator.
Click the Start button to begin the cleaning process and let it run uninterrupted to completion.
Important! If TFC prompts you to reboot, please do so immediately. If not prompted, manually reboot the machine anyway to ensure a complete clean.
Next run MBAM (MalwareBytes):

NOTE: Before saving MBAM please rename it to zztoy.exe....now save it to your desktop.

Please download Malwarebytes Anti-Malware and save it to your desktop.

alternate download link

MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.
  • 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 definition 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. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

Thank you for your quick response! I am away from the infected machine for the night, but I will follow your instructions first thing in the morning. I know for a fact that Spybot is no longer installed on that machine but I'll take a look and see if TeaTimer is still hanging around in there and I didn't know it. Also, MBAM is already installed. Should I uninstall it and start fresh? Thanks :thumbsup:

I tried to download and run TFC as well as run MBAM. Neither would work as it kept telling me the respective .exe files were infected. I will try to download and run the other two as well but if the pattern holds I probably won't be able to.

ETA: No go with either. I am rebooting to see if that will make a difference.

ETA2: Upon rebooting I am able to get things to run, until the infection takes over and stops the process. The MBAM scan ran for 1 minute 20 seconds before I got a runtime error 9 and a message that the file threatwork.exe is infected. I'll try another reboot to see if TFC can run in time and maybe that will prevent the malicious processes from running long enough for MBAM to work?

Ok we need to run RKill....then MBAm as quick as you can before the malware stops it again. . may need a few tries too. If you reboot start Rkill again.
You may have to run SAS in Normal too.

Please download Rkill by Grinler and save it to your desktop.Link 2
Link 3
Link 4
  • Double-click on the Rkill desktop icon to run the tool.
  • If using Vista, right-click on it and Run As Administrator.
  • A black DOS box will briefly flash and then disappear. This is normal and indicates the tool ran successfully.
  • If not, delete the file, then download and use the one provided in Link 2.
  • If it does not work, repeat the process and attempt to use one of the remaining links until the tool runs.
  • If the tool does not run from any of the links provided, please let me know.
You will need to run the application again if rebooting the computer occurs along the way.

Rkill worked from the first link upon a reboot from me. MBAM started to run but less than a minute into it came back with another runtime 9 error. I noticed that Ad-ware started running at about the same time, so I am uninstalling that now in case that was causing the conflict. I'll try again after that is done and hope that makes the difference.

ETA: No luck. Even with Ad-Aware gone MBAM has a runtime error after 20 seconds.

ETA2: Also cannot reboot into safe mode. It keeps rebooting when I choose that option but will only let me go through on Normal.

Ok,try this..
1. Uninstall Malwarebytes' Anti-Malware using Add/Remove programs in the control panel.
2. Restart your computer (very important).
3. Download and run this utility. Mbam clean
4. It will ask to restart your computer (please allow it to).
5. After the computer restarts, install the latest version from here. http://www.malwarebytes.org/mbam-download.php
Note: You will need to reactivate the program using the license you were sent.
Note: If using Free version, ignore the part about putting in your license key and activating.
Launch the program and set the Protection and Registration.
Then go to the UPDATE tab if not done during installation and check for updates.
Restart the computer again and verify that MBAM is in the task tray and run a Quick Scan and post that log.


Next run the SAS tool above. If Safe mode is not available run from Normal..

When I run the Mbam Clean I get the following:

SHGetValue failed with error code 0

It stops there and does not prompt to restart the machine.

What antivirus program is installed and running?

Disable your antivirus app (temporarily) and any other antimalware.
Then give mbam-clean one more try.

We have Symantec installed. I turned off the real-time protection on Symantec and clicked exit so that it is not running. But I still get the same error. SAS is installed, do I need to uninstall that and try again?

ETA: Uninstalled SAS from Control Panel and still no luck.

ETA2: Symantec just popped up a box identifying the following:

Bloodhound.Exploit.193

I'm wondering at this point if things are even salvageable. Would it be better just to wipe the hard drive and be done with it?

Not an unwise decision to make. In some instances an infection may have caused so much damage to your system that it cannot be completely cleaned or repaired. Wiping your drive, reformatting, and performing a clean install of the OS or doing a factory restore removes everything and is the safest action but I cannot make that decision for you.

Reformatting a hard disk deletes all data. If you decide to reformat, you can back up all your important documents, data files and photos. The safest practice is not to backup any autorun.ini or .exe files because they may be infected. Some types of malware may disguise itself by adding and hiding its extension to the existing extension of files so be sure you take a close look at the full name. After reformatting, as a precaution, make sure you scan these files with your anti-virus prior to copying them back to your hard drive.

The best proceedure is a low level format. This completely wipes the drive. Then reinstall the OS.
Use the free version of Active@ KillDisk.
Or Darik's Boot And Nuke

The best sources of Information on this are
Reformatting Windows XP
Michael Stevens Tech

Of course also feel free to ask anything on this in the XP forum. They'd be glad to help.

==============================

2 guidelines/rules when backing up

1) Backup all your important data files, pictures, music, work etc... and save it onto an external hard-drive. These files usually include .doc, .txt, .mp3, .jpg etc...
2) Do not backup any executables files or any window files. These include .exe/.scr/.htm/.html/.xml/.zip/.rar files as they may contain traces of malware. Also, .html or .htm files that are webpages should also be avoided.

Download Belarc Advisor - builds a detailed profile of your installed software and hardware, including Microsoft Hotfixes, and displays the results in your Web browser.
Run it and then print out the results, they may be handy.

Since we don't know exactly which infections we're dealing with here, we should take some precautions before we attempt to move files from the infected machine. Run the following on your clean computer, and make sure you insert your flash drives at the prompt.
Download and Run FlashDisinfector

Please download Flash_Disinfector.exe by sUBs and save it to your desktop.
  • Double-click Flash_Disinfector.exe to run it and follow any prompts that may appear.
  • The utility may ask you to insert your flash drive and/or other removable drives. Please do so and allow the utility to clean up those drives as well.
  • Hold down the Shift key when inserting the drive until Windows detects it to keep autorun.inf from executing if it is present.
  • Wait until it has finished scanning and then exit the program.
  • Reboot your computer when done.
Note: As part of its routine, Flash_Disinfector will create a hidden folder named autorun.inf in each partition and every USB drive that was plugged in when you ran it. Do not delete this folder...it will help protect your drives from future infection by keeping the autorun file from being installed on the root drive and running other malicious files.

Thank you so much for all of your help!! I don't know that I've got what it takes to do the reformat now, as I'm dealing with a very busy 16 month old day and night, so it might be time to replace the thing outright. And take a baseball bat to it for satisfaction :thumbsup: But thank you so much for your information and expertise!
