I believe my computer has been infected with Virtumonde, and I'm having great difficulty removing it from my system. I've read this can be hard to remove fully so I thought it'd be best to get some help from people who know more than myself.

The problems started on Tuesday evening, ads in websites became more malicious (i.e. "You have a virus! Click here to get the latest scanner!" or "Someone has left you a message") and I could no longer search Google or access Facebook. I ran McAfee Security Center 2008 on Wednesday and found nothing. I then installed and ran SpyBot - Search & Destroy on Thursday and it found numerous cases of "Virtumonde". Based on the description given by SpyBot, I believe this is causing the problems.

Trouble is, although SpyBot will recognise and "fix" the problem, it keeps returning. Whenever I do a scan I keep finding the Virtumonde virus. However, I am now able to search Google and access Facebook. But Virtumonde is still there, and understandly, I would like it gone.

Furthermore, my computer is now complaining that Automatic Updates has been switched off (despite the fact when I go to System in Control Panel I can see that it is on). When I click the button to turn Automatic Updates back on in the error window, it tells me that Windows Security Center cannot change these settings for me, and that I'll have to do it manually (despite the fact that Auto Updates are on). Could this be related to the Virtumonde virus?

I'd really appreciate some help on this. I've already backed up my files just in case, but if anyone can help me fix this problem, that'd be great.

Just so I don't waste your time let me tell you the other things I've already tried (other than McAfee and SpyBot): VundoFix (which didn't find anything), Symantic Vundo Removal Tool (didn't find anything) and Ad-Aware Free, which crashes half way through every scan after the 'Infected Files counter quickly accelerates to 447.

So, any help would be greatly appreciated. I've had a search on Google and found topics and blogs where people talk about registry files and deleting particular things etc., but I don't want to cause any more damage.

EDIT: I forgot to add, I'm running Windows XP.

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.

OK, the log is posted below. It did ask me to restart my system in order to remove something, but after restarting nothing seemed to happen. Is Malwarebytes supposed to automatically launch itself in order to get rid of the remaining malware, or has this been done without being shown?

or has this been done without being shown?


the delete after reboot would be invisible, it happenes during the windows load, however it's a good idea to rescan with MBAM to see if it worked, many files are protected by more hidden files and return

No. Try not. Do... or do not. There is no try.

There are no shortcuts or guarantees when it comes to malware removal. Sometimes it takes several efforts with different or the same tools to do the job. Even then, with some types of malware infections, the task can be arduous.

Rescan again with MBAM (Quick Scan) in normal mode and check all items found for removal. Don't forgot to reboot afterwards. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. When done, click the Logs tab and copy/paste the contents of the new report in your next reply.

That came up clean. Are there any more symptoms of infection?

Nope. Everything now seems to be fine - Google works perfectly, I've stopped getting malicious ads and I'm no longer being randomly redirected to other pages. The "Automatic Updates are OFF" problem has gone away too.

Thanks to everyone for their fantastic help - I'll definitely be keeping MBAM installed to use on a regular basis! :thumbsup:

You're welcome on behalf of the Bleeping Computer community.

If there are no more problems or signs of infection, you should Create 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 this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point. 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.
  • 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.
Vista Users can refer to these links: Create a New Restore Point and Disk Cleanup.

Tips to protect yourself against malware and reduce the potential for re-infection, be sure to read:
• "Simple and easy ways to keep your computer safe".
• "How did I get infected?, With steps so it does not happen again!".
• "Best Practices - Internet Safety for 2008".
• "Hardening Windows Security - Part 1 & Part 2".
• "IE Recommended Minimal Security Settings" - "How to Secure Your Web Browser".

• Avoid online gaming sites and peer-to-peer (P2P) or file sharing programs as they are a security risk which can make your system susceptible to a smörgåsbord of malware infections, remote attacks, exposure of personal information, and identity theft. Many malicious worms and Trojans target and spread across P2P files sharing networks and gaming sites. In some instances the infection may cause so much damage to your system that recovery is not possible and the only option is to wipe your drive, reformat and reinstall the OS. The best way to reduce the risk of infection is to avoid gaming sites and not use any P2P applications. Read P2P Software User Advisories and Risks of File-Sharing Technology.
