What are MFE_DS.dll Error Messages?


Dynamic Link Library MFE_DS.dll Errors

MFE_DS.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like MFE_DS.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like AlertManagerReg.exe - to follow. These files were created so that multiple programs (eg. McAfee Total Protection) could share the same MFE_DS.dll file, saving valuable memory allocation, therefore making your computer run more efficiently.

Unfortunately, what makes DLL files so convenient and efficient, also makes them extremely vulnerable to problems. If something happens to a shared DLL file, either it goes missing or gets corrupted in some way, it can generate a "runtime" error message. Runtime is pretty self-explanatory; it means that these errors are triggered when MFE_DS.dll is attempted to be loaded either when McAfee Total Protection is starting up, or in some cases already running. Some of the most common MFE_DS.dll errors include:

Your MFE_DS.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with McAfee Total Protection), or deleted by a malware infection. Furthermore, MFE_DS.dll file corruption could be caused from a power outage when loading McAfee Total Protection, system crash while loading MFE_DS.dll, bad sectors on your storage media (usually your primary hard drive), or quite commonly, a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.



How to Fix MFE_DS.dll Errors in 3 Steps (Time to complete: ~5-15 minutes)

If you're encountering one of the error messages above, follow these troubleshooting steps to resolve your MFE_DS.dll issue. These troubleshooting steps are listed in the recommended order of execution.


Step 1: Restore your PC back to the latest restore point, "snapshot", or backup image before error occurred.

To begin System Restore (Windows XP, Vista, 7, 8, and 10):

  1. Hit the Windows Start button
  2. When you see the search box, type "System Restore" and press "ENTER".
  3. In the search results, find and click System Restore.
  4. Please enter the administrator password (if applicable / prompted).
  5. Follow the steps in the System Restore Wizard to choose a relevant restore point.
  6. Restore your computer to that backup image.

If the Step 1 fails to resolve the MFE_DS.dll error, please proceed to the Step 2 below.

Step 2: If recently installed McAfee Total Protection (or related software), uninstall then try reinstalling McAfee Total Protection software.

You can uninstall McAfee Total Protection software by following these instructions (Windows XP, Vista, 7, 8, and 10):

  1. Hit the Windows Start button
  2. In the search box, type "Uninstall" and press "ENTER".
  3. In the search results, find and click "Add or Remove Programs"
  4. Find the entry for McAfee Total Protection 2019 (16.0 R20) and click "Uninstall"

Step 3: Perform a Windows Update.

When the first two steps haven't solved your issue, it might be a good idea to run Windows Update. Many MFE_DS.dll error messages that are encountered can be contributed to an outdated Windows Operating System. To run Windows Update, please follow these easy steps:

  1. Hit the Windows Start button
  2. In the search box, type "Update" and press "ENTER".
  3. In the Windows Update dialog box, click "Check for Updates" (or similar button depending on your Windows version)
  4. If updates are available for download, click "Install Updates".
  5. After the update is completed, restart your PC.

If Windows Update failed to resolve the MFE_DS.dll error message, please proceed to next step. Please note that this final step is recommended for advanced PC users only.



If Those Steps Fail: Download and Replace Your MFE_DS.dll File (Caution: Advanced)

If none of the previous three troubleshooting steps have resolved your issue, you can try a more aggressive approach (Note: Not recommended for amateur PC users) by downloading and replacing your appropriate MFE_DS.dll file version. We maintain a comprehensive database of 100% malware-free MFE_DS.dll files for every applicable version of McAfee Total Protection. Please follow the steps below to download and properly replace you file:

    Windows 10: C:\Program Files\Common Files\McAfee\AMCore\
    Windows 10: C:\Program Files\Common Files\McAfee\Casper\
  4. Restart your computer.

GEEK TIP : We must emphasize that reinstalling Windows will be a very time-consuming and advanced task to resolve MFE_DS.dll problems.

Download MFE_DS.dll Files (Malware-Tested 100% Clean)


CAUTION : We strongly advise against downloading and copying MFE_DS.dll to your appropriate Windows system directory. McAfee, Inc. typically does not release McAfee Total Protection DLL files for download because they are bundled together inside of a software installer. The installer's task is to ensure that all correct verifications have been made before installing and placing MFE_DS.dll and all other DLL files for McAfee Total Protection. An incorrectly installed DLL file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
