I have a version of the Vundo virus that refuses to be removed by Malwarebytes. Any ideas on what I can try?

In particular, these are the three entries that won't delete - even after re-booting:

Registry Values Infected:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run\nzalesifiz (Trojan.Agent) -> Delete on reboot.

and

C:\WINDOWS\dpnocfg.dll (Trojan.Vundo.H) -> Delete on reboot.
C:\WINDOWS\evepuyuq.dll (Trojan.Agent) -> Delete on reboot.

Any ideas on what I can do?

I've run Malwarebytes several times, both in regular mode and in Safe mode, to no avail.

Thanks in advance.

Do you have any software installed like spybot that might be interfering with the removal?

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 and scan with SUPERAntiSpyware Free
  • Double-click SUPERAntiSypware.exe and use the default settings for installation.
  • An icon will be created on your desktop. Double-click that icon to launch the program.
  • If asked to update the program definitions, click "Yes". If not, update the definitions before scanning by selecting "Check for Updates". (If you encounter any problems while downloading the updates, manually download them from here. Double-click on the hyperlink for Download Installer and save SASDEFINITIONS.EXE to your desktop. Then double-click on SASDEFINITIONS.EXE to install the definitions.)
  • In the Main Menu, click the Preferences... button.
  • Click the "General and Startup" tab, and under Start-up Options, make sure "Start SUPERAntiSpyware when Windows starts" box is unchecked.
  • Click the "Scanning Control" tab, and under Scanner Options, make sure the following are checked (leave all others unchecked):
    • Close browsers before scanning.
    • Scan for tracking cookies.
    • Terminate memory threats before quarantining.
  • Click the "Close" button to leave the control center screen and exit the program.
  • Do not run a scan just yet.
Reboot your computer in "Safe Mode" using the F8 method. To do this, restart your computer and after hearing your computer beep once during startup (but before the Windows icon appears) press the F8 key repeatedly. A menu will appear with several options. Use the arrow keys to navigate and select the option to run Windows in "Safe Mode".

Scan with SUPERAntiSpyware as follows:
  • Launch the program and back on the main screen, under "Scan for Harmful Software" click Scan your computer.
  • On the left, make sure you check C:\Fixed Drive.
  • On the right, under "Complete Scan", choose Perform Complete Scan and click "Next".
  • After the scan is complete, a Scan Summary box will appear with potentially harmful items that were detected. Click "OK".
  • Make sure everything has a checkmark next to it and click "Next".
  • A notification will appear that "Quarantine and Removal is Complete". Click "OK" and then click the "Finish" button to return to the main menu.
  • If asked if you want to reboot, click "Yes" and reboot normally.
  • To retrieve the removal information after reboot, launch SUPERAntispyware again.
    • Click Preferences, then click the Statistics/Logs tab.
    • 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.
    • Please copy and paste the Scan Log results in your next reply.
  • Click Close to exit the program.

Chewy,

Update. That seems to have helped a lot. I just ran Malwarebytes again and it came up clean. Firefox still loads webpages a little slow (at least it seems) but nothing like it was when I was having the problems.

Edit: webpages are still downloading slower than normal. I know the virus (when I had it) went in and changed my browser default settings (from Firefox to IE). Is it possible that it also made some adjustments to how Firefox interacts with my DSL connection?

Thanks in advance.

ATFCleaner clears the temp web files if used properly, that also causes a slowdown of web pages loading where you have visited before

When you cache too much, things get corrupt and web page loading can stall

OK we need a full scan with MBAM of all drives but CD/DVD, update first and run ATFCleaner on all broswers

EDIT: Also, Malwarebytes is asking me to restart to complete the removal process. Should I turn off my System Restore before rebooting?

Latest - ran quick scans for Malwarebytes (in regular mode) and SuperAntiSpyware (in safe mode). Both came up clean, but Firefox still runs sluggish.
