Hello!

Yesterday I noticed my google search links were being redirected (most often to a STOPzilla site). It didn't do it every time, but maybe once every 5 clicks. If I hit the back button to return to my google search results and then re-clicked the link, it would go to the correct site.

I ran Spybot, which found "Virtumonde.prx", and fixed it there. But after running the Spybot scan again, the malware entry reappeared. I googled around and found several Virtumonde fixes, including Malwarebytes. I ran that, found the problem again and fixed it. It appeared to have worked. To be safe, I also ran TDSSKiller, Symantec's Vundo remover, and VundoFix.

However, now when I reboot, I get an RUNDLL error saying:

"Error loading C:\windows\imawegumesawe.DLL
The specified module could not be found."

I went into MSConfig.exe and unchecked that startup command. On reboot it re-added itself. I went into the registry and deleted the entry (HKEY_LOCAL_MACHINE\software\microsoft\windows\currentversion\run - it was listed as "Ezofuluga" with the data 'rundll.exe C:\WINDOWS\imawegumesawe.dll",startup').

Of course, on reboot it returned.

I ran HijackThis and, without posting the entire log (I hope one line is okay) it showed this:

O4 - HKLM\..\Run: [Ezofuluga] rundll32.exe "C:\WINDOWS\imawegumesawe.dll",Startup

Now, to top it off, my google search results are still being redirected. :(

I didn't have HijackThis fix it because I wanted to see what you guys said.


FYI, running Windows XP
Can anyone help me get this file off my computer?

Hello and welcome.
Its not unusual to receive such an error after using specialized fix tools.

A "Cannot find...", "Could not run...", "Error loading... or "specific module could not be found" message is usually related to malware that was set to run at startup but has been deleted. Windows is trying to load this file but cannot locate it since the file was mostly likely removed during an anti-virus or anti-malware scan. However, an associated orphaned registry entry remains and is telling Windows to load the file when you boot up. Since the file no longer exists, Windows will display an error message. You need to remove this registry entry so Windows stops searching for the file when it loads.

To resolve this, download Autoruns, search for the related entry and then delete it.

Create a new folder on your hard drive called AutoRuns (C:\AutoRuns) and extract (unzip) the file there. (click here if you're not sure how to do this.)
Open the folder and double-click on autoruns.exe to launch it.
Please be patient as it scans and populates the entries.
When done scanning, it will say Ready at the bottom.
Scroll through the list and look for a startup entry related to the file(s) in the error message.
Right-click on the entry and choose delete. --> imawegumesawe.DLL
Reboot your computer and see if the startup error returns.

Next run MBAM (MalwareBytes):

Please download Malwarebytes Anti-Malware and save it to your desktop.
Download Link 1
Download Link 2MBAM 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. Temporarily disable such programs or permit them to allow the changes.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
    For instructions with screenshots, please refer to the How to use Malwarebytes' Anti-Malware Guide.
  • 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 definition 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. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

Wow! Thank you! It worked perfectly (knocking on wood)!

I was literally just minutes from formatting, I was just doing some last minute copying. If nothing else good came out of this malware, I now have current backups that I've been putting off for months!

Thanks for your time and excellent instructions. Everything appears back to normal. So, I'm saved this time. ;)

You guys ROCK!
No offense, but I hope I never need you again! ;)

I did run the scan and it came back clean. I'm going to head over to the security part of the forum and, hopefully, get some ideas for a better defense to prevent future infections.

OK,good idea. Now 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". Disk Cleanup will scan your files for several minutes, then open.
  • Click the "More Options" tab, then click the "Clean up" button under System Restore.
  • Click Ok. You will be prompted with "Are you sure you want to delete all but the most recent restore point?"
  • Click Yes, then click Ok.
  • Click Yes again when prompted with "Are you sure you want to perform these actions?"
  • Disk Cleanup will remove the files and close automatically.
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:Avoid gaming sites, pirated software, cracking tools, keygens, and peer-to-peer (P2P) file sharing programs. They are a security risk which can make your computer susceptible to a smörgåsbord of malware infections, remote attacks, exposure of personal information, and identity theft. Many malicious worms and Trojans spread across P2P file sharing networks, gaming and underground sites. Users visiting such pages may see innocuous-looking banner ads containing code which can trigger pop-up ads and malicious Flash ads that install viruses, Trojans and spyware. Ads are a target for hackers because they offer a stealthy way to distribute malware to a wide range of Internet users. The best way to reduce the risk of infection is to avoid these types of web sites and not use any P2P applications. Read P2P Software User Advisories and Risks of File-Sharing Technology.

Keeping Autorun enabled on USB and other removable drives has become a significant security risk due to the increasing number of malware variants that can infect them and transfer the infection to your computer. To learn more about this risk, please read:

It appears I spoke too soon. While the problem appeared solved for several reboots, it suddenly re-appeared. I opted to format my HD, which predictably resolved the problem.

FYI, in case others encounter this issue, I notice this malware caused my google search results to redirect links to anti-malware sites. Most often, STOPzilla, among a few others. I never tried to download software from those site, so I can't say if they were legitimate sites or not (probably not).

But still, I thank bleepingcomputer.com for offering the best help available. I hope my input will ultimately contribute to a permanent fix to this malware.
