I Think It's Vundo...

It all started about 5 days ago when firefox was acting slow and my XP computer was taking forever to start up. Pretty unusual because my computer and internet are both pretty good. I kept running norton 360 2.0 and it wasn't catching anything. Then yesterday I got this annoying little thing where windows explorer turns off, with the error message "Windows Explorer has encountered a problem and needs to close. We are sorry for the inconvenience." I click to see the error message and it says:
"AppName: explorer.exe AppVer: 6.0.2900.3156 ModName: rocketdock.dll
ModVer: 0.0.0.0 Offset: 0000b1db"

I send the error report and then explorer starts back up.... and the same thing happens again. MY desktop also goes away and it replaced with active desktop recovery. By now I'm thinking screw Norton, I have a problem. I download windows defender and (drumroll) I have Win32/Vundo.gen!M. So i go through the steps to delete that with windows defender (quarantine, then remove) but my computer is still funny. So I use Internet Explorer to get Vundofix (firefox still won't work) and I go through the steps there. It scans my computer and says I'm clear. Explorer is still in a restart loop, so I go back to Google and read somewhere that in HiJackthis, you can tell if you have Vundo by the 02 and 020 DLL entries matching.

O2 - BHO: {a90ebaf4-f10b-10cb-5074-bf47727c7c9d} - {d9c7c727-74fb-4705-bc01-b01f4fabe09a} - C:\WINDOWS\system32\wnvpyvrh.dll
O20 - AppInit_DLLs: wnvpyvrh.dll

Woah. I still have Vundo. I only get those popups I hear about when I visit my school's website. Other than that, my computer is just sluggish and my internet from Firefox sucks, and Explorer is messed up.

Windows defender said that the virus was in my Norton files, so I got rid of that and got the free McAfee enterprise download from my school. Still no signs of any problems. Windows defender now says I'm clean too, which is a lie, explorer is being retarded as we speak with its loop.

Please Help!

Welcome to BC caveman10493

Please print out and follow the instructions for using "Vundofix". -- If using Windows Vista be sure to Run As Administrator.
  • Click the Scan for Vundo button.
  • Once it's done scanning, click the 'Fix Vundo' button.
  • After running VundoFix, a text file named vundofix.txt will automatically be saved to the root of the system drive, usually at C:\vundofix.txt.
  • Please copy & paste the contents of that text file into your next reply.
-- If you receive this error: "Run-time error '339': Component 'comdlg32.ocx' or one its dependencies not correctly registered: a file is missing or invalid", a new copy and instructions on where to put it can be found here.

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

  • Make sure you are connected to the Internet.
  • Double-click on Download_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 and you may be prompted to restart your computer. (see Note below)
  • 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.
Instructions with screenshots if needed.

Note: If MBAM encounters a file that is difficult to remove, you will be presented with 1 of 2 prompts. Click OK to either and let MBAM proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot will prevent MBAM from removing all the malware.

I think it is still broken because stupid McAfee blocked the registry actions. I'm not sure whether it blocked malware registry actions or helpful registry actions.

Did you reboot the computer after using MBAM? If it encounters a file that is difficult to remove, you need to restart the computer so the malware can be fully removed. Failure to do so will prevent MBAM from removing all the malware. Your log indicates some files will be deleted on reboot. If you have not rebooted, make sure you do this. When done, rescan again with MBAM, click the Logs tab and copy/paste the contents of the new report in your next reply.

If McAfee is blocking the registry fixes, you are going to have to tell it not to do that or temporarily disable it from doing so.
