After downloading a torrent from FrostWire 4.0 I started to notice weird things happening on my pc
Right after that I deleted the file I downloaded.

First the explorer would keep crashing.
then I could not connect to many sites.
My computer was a bit slower
And sometimes when I was running FireFox 3.0 the trojan would execute another firefox window telling me I'm infected and to download their software
So I downloaded a beta version of McAfee Total Protection
When I searched the trojoan on google I found a page about it on McAfee's website and lots of people told me that site isn't safe.
I think it is attached to explorer.exe and winlogon.exe because when I delete them I reboot and they come back again.

I am running under Windows XP Professional ServicePack2

I have a 1.8GHz P-4
512 SDRAM

I used FireFox 3 during the attack and I am now using version 2

McAfee has detected two files after I did a scan/clean
(these files are in memory I believe and recreate upon restart)

1.) File name: EFCDUONF.dll
detection name: Vundo.gen.h

2.) File name: LCELPILA.dll
detection name: Vundo.gen.h


I appreciate any help regarding this problem.

Hello and welcome. Please run a few tools and post back the logs.

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. Reagardless 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.

McAfee keeps telling me it has removed the vundo trojan in the system restore folder, it keeps popping up! I am currently running the SUPER scan. And it keeps finding the vundo trojan but in different locations. SUPER hasn't detected anything in memory. So why do these trojans keep comming back after being removed?

It's running smooth now. I just hope that trojan doesn't come back, it always seem to come back somehow, like their is a hidden master file somewhere.

Ok ley's do one more think to help prevent that.

Now you should Set a New Restore Point to prevent possible reinfection from an old one. Some of the malware you picked up could have been saved in System Restore. Since System Restore is a protected directory, your tools can not access it to delete these bad files which sometimes can reinfect your system. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state.

The easiest and safest way to do this is:
  • Go to Start > Programs > Accessories > System Tools and click "System Restore".
  • Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name then click "Create". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
  • Then use Disk Cleanup to remove all but the most recently created Restore Point.
  • Then go to Start > Run and type: Cleanmgr
  • Click "OK".
  • Click the "More Options" Tab.
  • Click "Clean Up" in the System Restore section to remove all previous restore points except the newly created one.
