Believe it or not, Microsoft did a really decent job with Windows Defender compared to the heavily enforced Edge.

It isn’t perfect, but it is a respectable free solution for antimalware system protection.

However, there appears to be a plethora of Windows Defender error prompts, with one, in particular bearing the 0x80016ba code.

There are several reasons why this problem appears, and we’ve included a list of potential solutions.

Check it out if you’re having trouble with the Windows mentioned above Defender problem number 0x80016ba.

How can I fix the 0x80016ba problem in Windows Defender?

1. Turn off Windows Defender

1. Use the search bar or the notification area to open Windows Security.
2. Choose between virus and threat prevention.
3. Open the settings for virus and threat protection.
4. Both Real-time and Cloud-delivered protection should be disabled.
5. Exit Windows Defender Center and reactivate your third-party antivirus.

Due to system conflicts, only one antimalware tool can be active at any given moment. It’s a no-no to have two antivirus programs running simultaneously, especially when both work in the background and provide real-time protection.

As a result, you must make a decision. Whether you’ll employ a native antimalware program or a third-party alternative to combat malware.

Furthermore, while most antivirus solutions stop Windows Defender automatically upon installation, some of them may not.

If you’ve already made your decision and installed a third-party antivirus, ensure sure Windows Defender is turned off afterwards.

Of course, this only applies if you’re running a specialist antivirus program. If you choose to use Windows Defender instead and the problem keeps reappearing, please make sure you follow the procedures.

2. Make a system update

1. Type update into the Windows Search box, and then select Check for updates from the results list.
2. Install any pending updates by clicking the Check for Updates button.
3. View installed updates history, on the other hand, is located in the same section.
4. Now, go to Uninstall updates and uninstall the most recent security update.

The 0x80016ba error code can be caused by several reasons: a bad definition update.

If you can’t find Windows Defender or can’t run a scan, we recommend that you upgrade your system.

Security updates are the most often sent on Windows 10, and it’s possible that one of them caused the issue.

Updates are now mainly given automatically, but they may be delayed depending on your settings. As a result, manually checking for updates isn’t a bad idea.

You can also seek for improvements by uninstalling recent Windows Defender-related upgrades.

3. Scanning huge, compressed files should be avoided (ZIP, ISO, CAB)

1. Make a new folder and call it whatever you like.
2. In this newly created folder, place all huge, archived files.
3. From the notification area, launch Windows Defender.
4. Virus and threat protection is an option.
5. Open the settings for virus and threat protection.
6. Scroll down and select Add or delete exclusions from the drop-down menu.
7. Select Folder from the drop-down menu when you click Add an exclusion.
8. Look for the folder you want to exclude and add it as an exclusion.

Large chunks of compressed data have also been reported to trigger this problem by some users. Specifically, the scanning technique was performed as expected until compressed or archived files were used.

The Defender will then crash, and the error prompt will appear. Starting with ISO files and progressing through Microsoft‘s own CAB extensions, this covers all standard file formats.

Compared to third-party applications, Windows Defender makes file format exclusions a little more challenging to work with.

You can put all of your large, archived files in one folder and keep that folder out of subsequent scans. The in-scan errors should now be resolved.

However, because those formats are frequently the source of the virus, there is a risk aspect involved.

Follow the procedures we described above to exclude a specific folder from Windows Defender’s screening routine.

4. Verify that the Windows Defender service is running

1. Restart your computer after uninstalling a third-party antivirus.
2. To open the elevated Run command-line tool, use Windows key + R.
3. Type services.msc into the command prompt and hit Enter.
4. Scroll to the bottom of the page until you see Windows Defender Antivirus Service.
5. It should start automatically (this is required) however, it may be altered to Manual owing to a collision with another tool. If this is the case, right-click on it and select Properties from the menu.
6. Change the Startup type to Automatic and save your settings.
7. Restart your computer.

Windows Defender cannot be uninstalled from Windows 10. It can be muted (as previously stated), but its dedicated service will continue to operate in the background.

Unless it’s manually halted or by a third-party antivirus. In many cases, that service is the likely cause of Windows Defender failure.

The dedicated service, in particular, should consistently execute in the background, starting with the system shell.

This is especially true if you use Windows Defender for real-time protection or scheduled scans. The Windows Defender service is now frequently deactivated for unknown reasons.

Some third-party apps will limit it, but it should always be enabled if you’re simply using Windows Defender for system security.

As a result, we recommend using the methods above to check Windows Defender’s dedicated service.

5. Restart your computer

1. All vital files from the system partition should be copied to a data partition, external disk, or the cloud.
2. To open Settings, press Windows key + I.
3. Select Update & Security from the drop-down menu.
4. Choose Recover.
5. Under Reset, this PC clicks Get started.
6. Select Remove Everything to begin the restoration process.

Finally, there’s looking into rehabilitation methods to resolve the problem and eliminate the risk of recurrence completely.

Some users claim that the Windows 10 system update generates Windows Defender problems.

Microsoft Security Essentials was not entirely deleted when specific customers updated to Windows 10 from Windows 7. This results in a clash between the new and old native security solutions.

Aside from a clean system reinstall, the best remedy that comes to mind for this is to reset your PC to factory settings.

You’ll effectively have a brand-new Windows 10 machine without any Windows 7 files colliding. We recognize that this is time-consuming and that you will lose some data in the process.

However, we believe that this is a small price to pay for a well-performing system. If you’re not sure how to restore factory settings on your PC, please be sure to follow the procedures outlined above.

We hope that our solutions assisted you in resolving the 0x80016ba Microsoft Security Essentials problem code in Windows 10.
