Hi there,

I have a laptop running Windows XP Professional. When I either open Firefox or Internet Explorer and browse/check email/do anything, popups keep on popping up on my machine. Most of the popups ask me to buy a product called RegCure and sometimes the popops are targetted to what I am browsing or currently typing!

Another symptom is, when I am using firefox and browsing, Internet Explorer launches on its own and tabs keep on opening and Internet Explorer consumes a whole heap of memory. I have to launch the Task Manager and terminate Internet Explorer.

When I scan with Symantec AntiVirus, it tells me that the machine is infected with Trojan.Vundo. However, Symantec is unable to remove it. It is just annoying to say the least. I have even tried downloading and running the VundoFix tool that Symantec developed to exclusive fix Trojan.Vundo. But that tool doesn't even catch the virus. The infected registry keys mentioned on the the Symantec website do not exist in my registry.

I have spent 6 hours trying to fix this on my own and I couldn't get anywhere. I really need help and will greatly appreciate your guidance.

Thanks,
Joe

While I research the regcure rogue would you do this?

Please download ATF Cleaner by Atribune & save it to your desktop.
  • Double-click ATF-Cleaner.exe to run the program.
  • Under Main "Select Files to Delete" choose: Select All.
  • Click the Empty Selected button.
  • If you use Firefox browser click Firefox at the top and choose: Select All
  • Click the Empty Selected button.
    If you would like to keep your saved passwords, please click No at the prompt.
  • If you use Opera browser click Opera at the top and choose: Select All
  • Click the Empty Selected button.
    If you would like to keep your saved passwords, please click No at the prompt.
  • Click Exit on the Main menu to close the program.
Note: On Vista, "Windows Temp" is disabled. To empty "Windows Temp" ATF-Cleaner must be "Run as an Administrator".


Please download Malwarebytes Anti-Malware (v1.34) and save it to your desktop.
alternate download link 1
alternate download link 2
If you have a previous version of MBAM, remove it via Add/Remove Programs and download a fresh copy.
  • 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. Alternatively, you can update through MBAM's interface from a clean computer, copy the definitions (rules.ref) located in C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware from that system to a usb stick or CD and then copy it to the infected machine.
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. 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 after scanning with MBAM. Please temporarily disable such programs or permit them to allow the changes.

Thanks for the super quick reply DaChew!! Really appreciate it.

I have run ATF-Cleaner and Malwarebytes and here is the Malwarebytes' log. It caught 26 infected objects. All were Trojan.Vundo.H. 3 files could not be deleted and required me to reboot the machine. As soon as the machine rebooted I have logged in here to post the log. So far I do not see any popups. Should I assume that Trojan is take care of? Please let me know.

Thanks again for your kind help.

Regards,
Joe

    • Under Scanner Logs, double-click SUPERAntiSpyware Scan Log.
    • If there are several logs, click the current dated log and press View log. A text file will open in your default text editor.

You were right! I thought Malwarebytes took care of Vundo. I was so surprised to see SUPERAntiSpyware catch 10 more files that were infected with Vundo. They are now quarantined and here is the log.

I am trying to understand how I got Vundo on my system. I watch sport streams on the Internet by installing the OOX and SPVOD plug-ins in Internet Explorer. Can one of these add-ons be infected? Other than that I do not do anything questionable on my machine.

Thanks for all the help Chewy. Do you think we got rid of Vundo completely now?

Regards,
Joe

It can take 2 or 3 passes with 2 or 3 scanners to get it all sometime, and even then there may a few broken fragments show up later in scans with updated programs.

Did MBAM come back clean in that last scan?
