Hi,

I'm trying to open Autorun on a CD to set up a new router, but everytime I try to open it, I get an error box that says: "This application has failed to start because MFC71U.DLL was not found. Re-installing the application may fix this problem."

So I downloaded the MFC71U.DLL file and put it in Windows>system32, but I still can't open Autorun. Should I have put this dll application in a different folder?

Thank you,

Julie

It's likely that your original .dll was corrupt not actually missing. Use the following method to install your new copy. You can skip the portion about the zipped file due to the fact you have already downloaded it.

go to My Computer or Windows Explorer and find your way to C:\Windows\System32\ now look for the file MFC71U.DLL and right click on it and select Rename .. add old to the beginning (oldMFC71U.DLL). Go back to your desktop and open the zipped file (open it to desktop)> copy the file to C:\Windows\System32\ shut down the windows and reboot. The problem should be gone. You can now delete the zip and file from the desktop. Keep us updated.

Thanks, but it didn't work. I did it exactly as written (I even re-downloaded the file again).

Any other suggestions?

Thanks again,

Julie

Hi Julie, I am moving us to the Am I Infected forum from XP. I want to be certain there is no malware at faault.

First TFC by OT
Please download TFC by Old Timer and save it to your desktop.
alternate download link
Save any unsaved work. TFC will close ALL open programs including your browser!
Double-click on TFC.exe to run it. If you are using Vista, right-click on the file and choose Run As Administrator.
Click the Start button to begin the cleaning process and let it run uninterrupted to completion.
Important! If TFC prompts you to reboot, please do so immediately. If not prompted, manually reboot the machine anyway to ensure a complete clean.


Next run MBAM (MalwareBytes):

Please download Malwarebytes Anti-Malware (v1.44) and save it to your desktop.alternate download link 1
alternate download link 2
MBAM 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.
  • 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.

Thank you. I ran Old Timer, rebooted, downloaded Malwarebytes (no problems), updated and scanned. It found 20 infections, mostly Trojans. I removed the infections, rebooted, and I'm still getting the same error message regarding the dll application when I try to use the Autorun on the CD.

Thanks for suggesting the virus scan. I had scanned earlier today with McAfee and removed a couple Trojans, but Malwarebytes found even more. I do think that the Fake Alert one returned after McAfee supposedly took care of it. I will scan again tomorrow.


Any other ideas about the missing dll application that actually isn't missing now because I re-downloaded it?

Thank you,

Julie

Hello please post the scan log. So I can see if these infectiions are blocking or changing files.

Also there may be a damaged one trying to run. 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.
{ MFC71U.DLL }
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.
Reboot your computer and see if the startup error returns.

I ran the AutoRuns scan and I didn't see anything related to the MFC71U.DLL. I did see a handful of orphaned items and deleted those hoping that would solve the problem, but I just rebooted and tried to open the CD AutoRuns file and got the same error DLL message again.

Select the option for Safe Mode using the arrow keys.
Then press enter on your keyboard to boot into Safe Mode
.

Double-click ATF-Cleaner.exe to run the program.
Under Main "Select Files to Delete" choose: Select All.
Click the Empty Selected button.

If you use Firefox or Opera browser click that browser at the top and choose: Select All

On the left, make sure you check C:\Fixed Drive.
Perform a Complete scan. After scan,Verify they are all checked.
Click OK on the summary screen to quarantine all found items.
If asked if you want to reboot, click "Yes" and reboot normally.

The SUPER found one more problem. Here's the log:

SUPERAntiSpyware Scan Log

C:\PROGRAM FILES\THE PRINT SHOP 22\THE PRINT SHOP FORM CREATOR\ADMIN\PSWDMNGR.DLL


After quarantining, I rebooted, then tried opening the autorun again from the CD and still got the same error message.

I appreciate your help. Do you have any other suggestions?

Julie

P.S. How strange that this malware was hiding in my Print Shop program file. I opened Print Shop after removing the Adware.Vundo/Variant and it works fine.

Edited to ask - do you that it is possible that this threat detection was a false positive??

No, but I am now working with Cyfre on another method to do this (wirelessly).

So even though I didn't get the dll problem resolved, I think the computer is now squeaky clean. :thumbsup:

Hopefully that dll problem won't come back to haunt me in the future.

I greatly appreciate your time and help!

Hello,

You're sharp. :thumbsup:

Yes, it is a different computer. Yesterday, when you had me running the virus scans on my desktop, I thought it might be a good idea to check my laptop while I was at it. I'm really glad I did as I thought that I had gotten rid of everything with the McAfee last week. When I rescanned the laptop with McAfee again a couple of days ago, it said it was clean. But when you told me about the SUPER, I thought I should scan with it just to be certain.

I thought it would only be fair to get in line with a new post in the other virus forum rather than continuing on in this thread with a new problem. I hope that was the right thing to do.

Btw, I dumped the McAfee today (coincidentally, my subscription was going to expire in a couple of days), and I'm now on a 30 day trial with Kaspersky. I already like it much better. It stopped two worms this afternoon and it offers so much more protection. I'll scan with it overnight tonight to see what it finds.

Kind regards,

Julie
