What are VSOMod.dll Error Messages?

Dynamic Link Library VSOMod.dll Errors

VSOMod.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like VSOMod.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like Setup.exe - to follow. These files were created so that multiple programs (eg. McAfee Total Protection) could share the same VSOMod.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 VSOMod.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 VSOMod.dll errors include:

Access Violation at address - VSOMod.dll.
VSOMod.dll could not be found.
Cannot find C:\Program Files\McAfee\MfeAV\VSOMod.dll.
Cannot register VSOMod.dll.
Cannot start McAfee Total Protection. A required component is missing: VSOMod.dll. Please install McAfee Total Protection again.
Failed to load VSOMod.dll.
The application has failed to start because VSOMod.dll was not found.
The file VSOMod.dll is missing or corrupt.
This application failed to start because VSOMod.dll was not found. Re-installing the application may fix this problem.

Your VSOMod.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, VSOMod.dll file corruption could be caused from a power outage when loading McAfee Total Protection, system crash while loading VSOMod.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 VSOMod.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 VSOMod.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):

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

If the Step 1 fails to resolve the VSOMod.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):

Hit the Windows Start button
In the search box, type "Uninstall" and press "ENTER".
In the search results, find and click "Add or Remove Programs"
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 VSOMod.dll error messages that are encountered can be contributed to an outdated Windows Operating System. To run Windows Update, please follow these easy steps:

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

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