Hello,

I think my computer was recently attacked: A bunch of pop ups opened in Internet Explorer (I use Firefox as my default browser, however), and Windows firewall and security center told me that it was turned off. I figured I received a virus somehow, and I first scanned my computer with Spybot S&D. While it was scanning (extremely slowly), windows explorers would open up the Firefox directory, the Spybot directory, as well as Internet Explorer popups. I closed these immediately as they appeared on the screen.

Spybot found a whole bunch of entries, but at the end of the scan, the computer had a blue screen of death and I had to restart. I restarted in Safe Mode, and scanned again with Spybot, and entries for
Virtumonde.prx
Microsoft.WindowsSecurity.Center.FirewallBypass
Microsoft.WindowsSecurityCenter_Disabled
Refpron
TinyBar.C
Virtumonde
Virtumonde.Dll
Win32.Delf.rtk
Win32.Delf.uc
appeared. After removing these entries succesfully, I tried to open Lavasoft Ad-Aware, but windows gave me an Application Error: Exception EAccess Violation...
I restarted in Safe Mode again, and rescanned with Spybot, and entries for
Virtumonde
Microsoft.WIndowsSecurityCenter_Disabled
Win32.Delf.uc
were found again. I removed these entries again, but after ANOTHER reboot in safe mode, these entries remained.

What procedures should I take to clean my computer from these viruses? And how do I gain access to Ad-Aware?
Thanks in advance for the help.

Hi and welcome to BleepingComputer :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

Thank you for the reply.


I cannot access the internet from the infected computer - everytime I try to restart normally (not in safe mode) I receive a blue screen of death - but I downloaded Malwarebytes Anti-Malware onto a USB and installed it that way in safe mode. After scanning in with MAM in safe mode and attempting to remove all entries, the log file was as follows:

I then restarted as MAM requested, but as soon as I logged into my account (which is by the way the only account and has administrative controls), I received an error window saying "cli.exe was not found." There was also another window "rundll", and in about 5 seconds from logging in I get a blue screen of death. I restarted in safe mode, and rescanned with MAM, but this time 0 infected items were found, with a log as follows:

After the second scan, I restarted normally again, and this time again, within a few seconds of loggin in, I noticed that "cli.exe failed to initalize properly" and there were a bunch of command windows opening up, and again, a blue screen of death. I restarted once more normally, to see if I could catch what the exact messages were, and it seems the "rundll" window mentioned "xccdf16_090131a.dll", and the b.s.o.d. said "page_fault_in_nonpaged_area".

What procedures should I follow next? Please help, and thanks again.

Can you run safe mode with networking and access the web that way? I need to to try another program.

Please print out and follow these instructions: "How to use SDFix". <- This program is for Windows 2000/XP ONLY.
When using this tool, you must use the Administrator's account or an account with "Administrative rights"
  • Disconnect from the Internet and temporarily disable your anti-virus, script blocking and any real time protection programs before performing a scan.
  • When done, the SDFix report log will open in notepad and automatically be saved in the SDFix folder as Report.txt.
  • If SDFix is unable to run after rebooting from Safe Mode, run SDFix in either Mode, and type F, then press Enter for it to finish the final stage and produce the report.
  • Please copy and paste the contents of Report.txt in your next reply.
  • Be sure to renable you anti-virus and and other security programs before connecting to the Internet.
-- If the computer has been infected with the VirusAlert! malware warning from the clock and the Start Menu icons or drives are not visible, open the SDFix folder, right-click on either the XP_VirusAlert_Repair.inf or W2K VirusAlert_Repair.inf (depending on your version of Windows) and select Install from the Context menu. Then reboot to apply the changes.

Thanks for the reply.
I can't access the web in safe mode with networking for some reason.

I followed the instructions for installing and using SDFix, but after running the program (c:\sdfix\runthis.bat), within 30 seconds there are some brief flashes in the window and the titlebar where it says "SDFix" and then I get a blue screen of death.

Is there an alternative to this procedure or do you know how to fix this constant BSOD problem?

Thank you very much for your help so far.

Hmm...Do you think this is the best option? Will it completely clean the virus?

No, it will not clean clean the virus, but it may give us some functionality back.

What would be the subsequent procedures to clean the virus? I just want to get an overall sense, and I wonder if a clean install would be better?

I have also begun to backup my files to an external hard drive, but after about 30 minutes, a message comes up saying that "The system is shutting down. Please save all work in progress and log off. Any unsaved changes will be lost. This shutdown was initiated by NT AUTHORITY/SYSTEM" and I have about 60 seconds before the computer restarts.

I'm guessing this a part of the virus(es) that attacked my computer? Is there any way to remove this symptom so I can continue backing up my files without having to restart every 30 minutes?

The 30 minute limit could very well be the virus at work.

The next procedures would be an attempt at SDFix, Superantispyware, and online scan, and then possible rescans of Malwarebytes and superantispyware.

Sorry for the delayed response - I was searching for my windows CD. Now that I've found them, should I just follow the instructions on the microsoft website (http://www.microsoft.com/windowsxp/using/helpandsupport/learnmore/tips/doug92.mspx)? Are there any specific instructions given that I have a virus?

Thanks again for all the help thus far.

Back up any important files. Past that, go ahead an do the repair install and we can continue with your cleaning.
