What error message is displayed when accessing virus and threat protection?

Users generally encounter the following error message when accessing or using the virus and threat protection on Windows 11: Your IT administrator has limited access to some areas of this app. If you see this on the Windows Defender window, you have come to the right page. Go through the following sections to understand the causes and the most effective fixes for the error.

What can I do if virus and threat protection is not working?

Before we start fixing this issue, there are a couple of checks that you might want to perform:

Restart your PC – In some instances, this problem can be caused by a glitch, and a quick restart is all that’s needed to fix it. Install the latest updates – Sometimes, certain components can encounter glitches, and that can cause problems such as these. Keeping Windows updated is a great way to fix this issue. Check date and time – Issues like this can occur if the date or time isn’t correct on your PC. To fix it, you need to change time on Windows 11 and make sure it’s correct. Perform a System Restore – It’s possible that installed applications or settings are causing this issue. To fix it be sure to create a restore point and restore your system.

1. Run an SFC (System File Checker) scan

The SFC (System File Checker) scan is used to identify corrupt system files and replace them with their cached copy stored on the system. Running the scan will likely solve the problem if Windows Defender is corrupted. For a thorough scan of your system files, we recommend using a third-party tool that specializes in finding and repairing corrupted or damaged system files.

2. Uninstall any other third-party antivirus

If you have a third-party antivirus installed on the PC, it could conflict with the functioning of the virus and threat protection. Here’s how you can perform this action: Restoro’s technology replaces severely damaged Windows system files with clean, up-to-date ones from its secure online database. You can allow it to perform this action without harming your user data. This the ideal all-in-one tool for fixing Windows errors, PC crashes, or registry issues. It can boost the performance of your device and make it more secure within a few minutes. ⇒ Get Restoro Disclaimer: This program needs to be upgraded from the free version in order to perform some specific actions. Also, sometimes, when Windows detects a similar tool installed on the system, it disables Windows Defender to prevent the two from running into conflict. Hence, uninstalling the antivirus should be a direct approach to solving the error.

3. Use PowerShell

4. Turn on Real-time protection

After enabling real-time protection, you should be able to access virus and threat protection. For example, the toggle might be turned off either manually by you or by Windows itself if it detects a third-party antivirus.

5. Repair the Windows Security app

If a program throws errors on launch or during its functioning, repairing it could help. When you fix an app, Windows looks through its installation, identifies and replaces any problematic files, and checks its entries in the Registry. This is a quick troubleshooting method; you don’t lose any data or configured settings. SPONSORED

6. Run a malware scan

In many cases, it was reported that malware or virus was causing issues in launching the virus and threat protection. However, since the Windows Defender app is not working, you must use another tool to run a scan. Pick one of the best third-party antivirus software for Windows 11 and install it. After downloading the program, run a malware scan to find out and eliminate/quarantine any viruses present on the system. To ensure that there is nothing trying to stop your Virus and Threat Protection from working, a malware scan is essential. For a fast and advanced malware scan, we recommend ESET NOD 32. ESET is a complete antivirus with very advanced security features that will always protect you from threats. Plus, some amazing security features let you explore anything online safely.

7. Restart Security Center service

8. Make modifications to the Registry

Certain viruses are known to create entries in the Registry that conflict with the functioning of Windows Defender. If that’s preventing you from accessing virus and threat protection, deleting the above entries will solve the problem. If the above method doesn’t resolve the issue, you can also try fixing the broken registry items.

9. Enable Windows Defender using Registry

After making changes to the Registry, check if the problem with Windows Defender is solved, and you can access and make changes to it.

What can I do if the fixes listed here don’t work?

First of all, that’s an improbable scenario. However, if the solutions didn’t work, a restore point was unavailable, or system restore didn’t help, amongst other things, you can always reset Windows 11 to its factory settings. When you do that, the PC returns to the initial stage. In simple words, in the same stage, you first used it in terms of settings and stored data.

Why has virus threat protection stopped?

In most cases, when you run into this error, it is because you have some corrupted system files. Therefore, we always recommend running an SFC and DISM scan to look for any system-wide corruption and repair it to resolve some difficulties, such as the Windows Security issue. The above fixes should resolve the Windows 11 virus and threat protection not working issue and get things up and running. Many are still wondering whether Windows 11 needs antivirus, and in most cases, Windows Defender will do its job perfectly. However, some users prefer using third-party software.
