wow.dll error when I right click file in Windows Explorer

Recommended Posts

Hello, I have been receiving the following RunDLL error message when I right click a file in windows explorer: "There was a problem starting C:\users\studio~1\AppData\local\temp\sdktyxo\sevpnct\wow.dll . Specified module could not be found". Also, start up is slow and I am prompted to update my registry keys at start. I ran MalwareBytes Anti-Malware and got this report:

Attached is fine.

Malwarebytes Anti-Malware <---------your version is way out of date, at some point please update the program.


Here you go......

Please read the following information first.

You're infected with Rootkit.ZeroAccess, a BackDoor Trojan also.



One or more of the identified infections is known to use a backdoor.

This allows hackers to remotely control your computer, steal critical system information and download and execute files.

I would advice you to disconnect this PC from the Internet immediately. If you do any banking or other financial transactions on the PC or if it should contain any other sensitive information, please get to a known clean computer and change all passwords where applicable, and it would be wise to contact those same financial institutions to apprise them of your situation.

Though the infection has been identified and because of it's backdoor functionality, your PC is very likely compromised and there is no way to be sure your computer can ever again be trusted. Many experts in the security community believe that once infected with this type of trojan, the best course of action would be a reformat and reinstall of the OS. Please read these for more information:

How Do I Handle Possible Identify Theft, Internet Fraud and CC Fraud?


When Should I Format, How Should I Reinstall


I will try my best to clean this machine but I can't guarantee that it will be 100% secure afterwards.

Let me know what you decide to do. If you decide to go through with the cleanup, please proceed with the following steps.


Run RogueKiller again and click Scan

When the scan completes > click on the Registry tab

Put a check next to all of these and uncheck the rest: (if found)

[HJ INPROC][sUSP PATH] HKCR\[...]\InprocServer32 : (C:\Users\StudioBryanHanes\AppData\Local\Temp\sdktyxo\sevpnct\wow64.dll) [-] -> FOUND

[HJ INPROC][ZeroAccess] HKCR\[...]\InprocServer32 : (C:\$Recycle.Bin\S-1-5-18\$a557dfdef3dddded94da594ffe765ee2\n.) [x] -> FOUND

Now click Delete on the right hand column under Options


Next click on the Files tab and put a check next to these and uncheck the rest. (if found)

[ZeroAccess][FILE] @ : C:\$recycle.bin\S-1-5-18\$a557dfdef3dddded94da594ffe765ee2\@ [-] --> FOUND

Now click Delete on the right hand column under Options



Download Malwarebytes Anti-Rootkit from HERE

  • Open the folder where the contents were unzipped and run mbar.exe
  • Follow the instructions in the wizard to update and allow the program to scan your computer for threats.
  • Click on the Cleanup button to remove any threats and reboot if prompted to do so.
  • Wait while the system shuts down and the cleanup process is performed.
  • Perform another scan with Malwarebytes Anti-Rootkit to verify that no threats remain. If they do, then click Cleanup once more and repeat the process.
  • When done, please post the two logs produced they will be in the MBAR folder..... mbar-log.txt and system-log.txt

Bottom right corner of this page.


New window that comes up.




If no additional threats were found, verify that your system is now running normally, making sure that the following items are functional:

Internet access

Windows Update

Windows Firewall

If there are additional problems with your system, such as any of those listed above or other system issues, then run the fixdamage tool included with Malwarebytes Anti-Rootkit and reboot. It's located in the Plugins folder which is in the MBAR folder.

Just run fixdamage.exe.

Hi Charlie - I followed your advice, erased the items you noted found by RogueKiller, ran the Rootkit, cleaned up, and ran a second time with no threats found. I've attached the log reports from Rootkit. Everything seems to be running normally. If there are any other precautions I need to take, please let me know, otherwise THANK YOU for your assistance!

Well Done, lets run ComboFix to clear up any leftovers.

Please download and run ComboFix.

The most important things to remember when running it is to disable all your malware programs and run Combofix from your desktop.

Please visit this webpage for download links, and instructions for running ComboFix


Ensure you have disabled all anti virus and anti malware programs so they do not interfere with the running of ComboFix.

Information on disabling your malware programs can be found Here.

Make sure you run ComboFix from your desktop.

Give it at least 30-45 minutes to finish if needed.

Please include the C:\ComboFix.txt in your next reply for further review.


If you get the message Illegal operation attempted on registry key that has been marked for deletion after you run ComboFix....please reboot the computer, this should resolve the problem. You may have to do this several times if needed.

Looks Good......

Lets check for any adware while you're here:

Please download AdwCleaner from here and save it on your Desktop.

AdwCleaner is a reliable removal tool for Adware, Foistware, toolbars and potentially unwanted programs.

AdwCleaner is a tool that deletes :

· Adwares (software ads)

· PUP/LPI (Potentially Undesirable Program)

· Toolbars

· Hijacker (Hijack of the browser's homepage)

It works with a Search and Deletion method. It can be easily uninstalled using the "Uninstall" mode.

  1. Right-click on adwcleaner.exe and select Run As Administrator (for XP just double click) to launch the application.
  2. Now click on the Search tab.
  3. Please post the contents of the log-file created in your next post.

Note: The log can also be located at C:\ >> AdwCleaner[XX].txt >> XX <-- Denotes the number of times the application has been ran, so in this should be something like R1.


Please look over what was found......especially any folders, we're going to permanently delete it all in the next step....if there's something you may want to keep...please let me know and I'll explain to why it shouldn't be on your system.

If you see AVG Secure Search being targeted for deletion, Here's Why and Here. You can always Reinstall it.

Please note that Antivir Webguard uses ASK Toolbar as part of its web security. If you remove ASK by using Adwcleaner, Antivir Webguard will no longer work properly. Therefore, if you use this program please use the instructions below to access the options screen where you should enable /DisableAskDetections before using AdwCleaner.

You can click on the question mark (?) in the upper left corner of the program and then click on Options. You will then be presented with a dialog where you can disable various detections. These options are described below:

/DisableAskDetection - This option disables Ask Toolbar detection.

May have spoke too soon...I have some trouble with my web browser (IE 10.5). I am able to get to google, search for something, click through the link, etc., but I can't type anything directly into the address bar (for instance, can't type www. whatever .com, rather need to search for whatever and click through). Also having trouble clicking back. Is this related to the same virus?

Ok so I might have screwed this up - I originally looked for the restore point in ComboFix, which cause it to initiate another restore point and got rid of the first one it generate. I am able to go back the restore point that was created with MalwareBytes antiroot kit a few steps back. Should I go for that one instead??

. I downloaded GoogleChrome which seems fine so far

I recommend and use Chrome myself, it' a much safer than IE. Once you get used to using it, you find it's a much better browser.


You can reset or re-install Internet Explorer:

Out dated programs on the system are vulnerable to malware.

Please update or uninstall them:


Java™ 7 Update 1 <----please update, should be Update 21

Java version out of Date! <--------Go to control panel > Java > Update Tab > Update Now

Uncheck the box to install the Ask toolbar!!! and any other free "stuff".

If there's no update tab in Java, uninstall it and Download and install the latest version from Here

Uncheck the box to install the Ask toolbar!!! and any other free "stuff".


A little clean up to do....

Please Uninstall ComboFix: (if you used it)

Press the Windows logo key + R to bring up the "run box"

Copy and paste next command in the field:

ComboFix /uninstall

Make sure there's a space between Combofix and /


Then hit enter.

This will uninstall Combofix, delete its related folders and files, hide file extensions, hide the system/hidden files and clears System Restore cache and create new Restore point

(If that doesn't work.....you can simply rename ComboFix.exe to Uninstall.exe and double click it to complete the uninstall)


If you used DeFogger to disable your CD Emulation drivers, please re-enable them.


Please download OTC to your desktop.


Double-click OTC to run it. (Vista and up users, please right click on OTC and select "Run as an Administrator")

Click on the CleanUp! button and follow the prompts.

(If you get a warning from your firewall or other security programs regarding OTC attempting to contact the Internet, please allow the connection.)

You will be asked to reboot the machine to finish the Cleanup process, choose Yes.

After the reboot all the tools we used should be gone.

Note: Some more recently created tools may not yet be removed by OTC. Feel free to manually delete any tools it leaves behind.

Any other programs or logs you can manually delete.

IE: RogueKiller.exe, RKreport.txt, RK_Quarantine folder, C:\FRST, MBAR, etc....AdwCleaner > just run the program and click uninstall.


Any questions...please post back.

If you think I've helped you, please leave a comment > click on my avatar picture > click Profile Feed.

Take a look at My Preventive Maintenance to avoid being infected again.

Good Luck and Thanks for using the forum, MrC
