Strange .dll error message

By smurphydej ·
I am receiving a specific .dll message when I start my laptop. It is "Error Loading c:\windows\system32\wnxmmwyg.dll The specified module could not be found.

I tried looking up the error message however nothing was found. I have never seen "wnxmmwyg.dll" error message. Has anyone ever come across this before?

ps. my labtop is working fine just annoying that this pops up everytime I start the laptop

Never heard of that .dll....

by ---TK--- In reply to Strange .dll error messag ...

couple of things you can do but I would first start with the basics...

1.Run a spyware scan (spybot S&amp or Malwarebytes).
2.Check for corrupt files with check disk (run command, type cmd, type chkdsk /R, it will prompt you y/n hit y enter, then reboot.
3.Download CCleaner, and run a registry scan and clean that up.

If your still getting the error I would go into msconfig, run command > msconfig. Go to the start up tab. From here I would start disabling things, but I do have to warn you that if you disable the wrong thing it can and probably will cause your system become unstable... So, I would first disable a few at a time... Until the issue goes away, then re enable the other programs that you disabled...

If you get into trouble you can always get into the system with "safe mode" and undo what you did. After POST but before the windows load screen hit "F8" and choose Safe Mode...

It could be malware

by Jacky Howe In reply to Strange .dll error messag ...

Follow the steps below with the System started and restarted in Safe Mode with Networking. Running in Safe Mode loads a minimal set of drivers for the Operating System. You can use these options to start Windows so that you can modify the registry or load or remove drivers. If you can access the Internet use it to download the files.

If you can't access the internet to update MBAM try the instructions below to clear a path to the internet to be able to run MBAM. You can also download the updates for MBAM and run them from the USB.

From another System download and install Spybot, update it and copy the the installed folders to a USB Stick. Copy MBAM and the Update as well.

Removing malware from System Restore points
To remove the malware, you must first disable System Restore, then scan the system with up-to-date antivirus software - allowing it to clean, delete, or quarantine any viruses found. After the system has been disinfected, you may then re-enable System Restore. The steps for disabling System Restore vary, depending on whether the default Start Menu or the Classic Start Menu is being used.

Default Start Menu XP
If using the default Start Menu, click Start | Control Panel | Performance and Maintenance | System. Select the System Restore tab and check "Turn off System Restore".

Classic Start Menu XP
If using the Classic Start Menu, click Start | Settings | Control Panel and double-click the System icon. Select the System Restore tab and check "Turn off System Restore".

Start, right mouse click Computer and select Properties. Select Advanced System Properties, click contine and then System Protection. Untick the box nect to Local Disk C: and click on Turn System Restore off.

After scanning the system and removing the offending malware, re-enable System Restore by repeating the steps, this time removing the check from "Turn off System Restore".

Once you have restarted the Infected System in Safe Mode, navigate to the USB stick and run Spybot.

Download Spybot - Search & Destroy and install it. Update it.

Download Malwarebytes Anti-Malware, install it and update it.

<a href="" target="_blank"><u>Malwarebytes</u></a>

* Double-click mbam-setup.exe and follow the prompts to install the program.
* At the end, be sure a checkmark is placed next to Update Malwarebytes' Anti-Malware and Launch Malwarebytes' Anti-Malware, then click Finish.
* If an update is found, it will download and install the latest version.
* Once the program has loaded, select Perform Quick Scan, then click Scan.
* When the scan is complete, click OK, then Show Results to view the results.
* Be sure that everything is checked, and click Remove Selected.

If you encounter any problems while downloading the updates, manually download them from here and just double-click on mbam-rules.exe to install.
<a href="" target="_blank"><u>mbam-rules</u></a>

I would keep scanning with it until it is clean by closing out and rebooting and running it again.

Run this Rootkit Revealer GMer

Tip! If you want to write protect the USB drive/stick while you are working on an infected System.
In the recent release of Windows XP Service Pack 2 (SP2), a new feature was added by Microsoft to allow the write protection of USB block storage devices. This entails a simple Registry modification that requires no hardware devices to write protect thumb drives.

If the USB drive has no small switch for write protection you can turn it on through the Registry via Command Line.

REG ADD HKLM\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies /v WriteProtect /t REG_DWORD /d 1 /f

and one to turn it off but a System restart is required. Place the Batch file on the USB to turn it off.

reg delete HKLM\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies /f

If TaskManager has been disabled this will enable TaskManager to allow access to the Registry.

Command line removal or create Batch files.

Click Start Run and type cmd and then press Enter.

Execute the following commands in the command line in order to activate the registry editor and Task Manager:

reg delete HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System /v DisableTaskMgr /f

reg delete HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System /v DisableRegistryTools /f

With the new strains of Virus that have been created you may find it necessary to rename the executable files so that they will work. Rename mbam-setup.exe and then navigate to the install folder and rename mbam.exe. Do not change the files extension from .exe. Do the same with Spybot.

If it comes up clean

by Jacky Howe In reply to It could be malware

then try this.


Download and install CCleaner to tidy up your Registry. Backup the Registry as you go along, rescan again and again saving as you go until there are no errors left.

Cleaner: Windows

When you first open Ccleaner you will have an option to Analyze or Run Cleaner, after checking the left Pane and making your choices. Delete all Temp Files. If you scroll down you will see a greyed out box that has Advanced next to it. Left click on it and keep pressing OK to all of the responses. I normally Untick Windows Log Files and Memory Dumps as they may come in handy.

You don't have to install all of the add ons or shortcuts just the one to the Desktop.

Look in the log/history of your Anti-Virus software

by robo_dev In reply to Strange .dll error messag ...

often the AV software will quarantine a virus, yet the file name is still in the registry.

You may just need to go into the registry and clean out that reference.

That file name sounds very virus-like.
