此时，如果防病毒、防火墙和 Web 保护的安全提供商(no security providers for antivirus, firewall, and web protection)问题仍未解决，则很可能是由于某种常规无法解决的系统损坏。在这种情况下，您可以尝试全新启动、就地升级或修复(Fresh Start, In-place upgrade or Repair)来重置每个Windows组件。您可以尝试云重置(try Cloud Reset)，看看是否有帮助。
Hopefully, any of these solutions will work for you!
Windows Security says No Security Providers in Windows 11/10
If whеn you initiаte a virus scan in Windows Defender on Windows 11/10 and the scan doesn’t run; and then you check Windows Security settings and notice that there are no security providers for Antivirus, Firewall, and Web protection, then this post is intended to help you. In this post, we will identify possible causes, as well as provide the appropriate solutions you can try to remediate the issue.
This issue can be caused by but not limited to corrupt system files, malware infection, disabled security center service.
Windows Security says No Providers
If Windows Security is not working and showing a message that there are No Security Providers for Antivirus, Firewall, Web protection then, you can try our recommended solutions below in the order presented and see if that helps to resolve the issue.
- Make sure the Windows Security service is running
- Check for and delete rogue entries in the registry
- Uninstall third-party security software
- Perform Windows Defender Offline Scan at boot time
- Run SFC and DISM scan
- Perform System Restore
- Perform a Fresh Start, In-place upgrade repair or Cloud Reset
Let’s take a look at the description of the process involved concerning each of the listed solutions.
1] Make sure the Windows Security service is running
If the Windows Security Center service is turned off, you will most likely be faced with this issue. In which case, you need to verify that this essential service is running.
If this doesn’t resolve the issue, continue with the next solution.
2] Check for and delete rogue entries in the registry
Malware infection may be the cause of this issue. Some malware adds malicious or rogue entries in the registry that blocks legitimate AVs from running.
To check for and remove these entries, follow these steps:
- Press Windows key + R to invoke the Run dialog.
- In the Run dialog box, type regedit and hit Enter to open Registry Editor.
- Navigate or jump to the registry key location below:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Image File Execution Options
- On the right pane, see if there’s any entry for MSASCui.exe, MpCmdRun.exe, or MsMpEng.exe.
- If any of these entries are present, then right-click and click Delete.
If you do not find any of these entries, then all is fine and you don’t need to do anything. If that’s the case, proceed with the next solution.
3] Uninstall third-party security software
Sometimes, when you install any third-party security software, it conflicts with Windows Defender, the inbuilt security software for Windows 10. When this conflict happens, critical services can be disabled which can cause this issue.
In this case, uninstalling the third-party security software with its native uninstaller could resolve the issue. If not, continue with the next solution.
4] Perform Windows Defender Offline Scan at boot time
Windows Defender in Windows 10 allows you to conduct an offline scan – also referred to as Windows Defender boot-time scan – that can help you get rid of persistent and difficult-to-remove malware and malicious software, using the latest threat definitions.
If the issue persists after you have performed the offline scan, you can try the next solution.
5] Run SFC and DISM scan
If you have system file errors, you may encounter this issue.
The SFC/DISM is a utility in Windows that allows users to scan for corruptions in Windows system files and restore corrupted files.
For ease and convenience, you can run the scan using the procedure below.
- Press Windows key + R to invoke the Run dialog.
- In the Run dialog box, type notepad and hit Enter to open Notepad.
- Copy and paste the command below into the text editor.
@echo off
date /t & time /t
echo Dism /Online /Cleanup-Image /StartComponentCleanup
Dism /Online /Cleanup-Image /StartComponentCleanup
echo ...
date /t & time /t
echo Dism /Online /Cleanup-Image /RestoreHealth
Dism /Online /Cleanup-Image /RestoreHealth
echo ...
date /t & time /t
echo SFC /scannow
SFC /scannow
date /t & time /t
pause
- Save the file with a name and append the .bat file extension – eg; SFC-DISM-scan.bat.
- Repeatedly run the batch file with admin privilege (right-click the saved file and select Run as Administrator from the context menu) until it reports no errors.
- Restart your PC.
On boot, check to see if the issue is resolved. If not, proceed with the next solution.
6] Perform System Restore
If you noticed that the problem occurred recently, it’s entirely possible that the issue was facilitated by a change that your system has gone through recently.
If you have no idea what changed that might have ended up breaking the Windows Security Center, you can use System Restore (any changes like application install, user preferences, and anything else made after the restore point will be lost) to revert to date before when you noticed the issue.
To perform System Restore, do the following:
- Press Windows key + R.
- In the Run dialog box, type rstrui and hit Enter to open up the System Restore Wizard.
- Once you arrive at the initial screen of System Restore, click Next to advance to the next window.
- At the next screen, start by checking the box associated with Show more restore points.
- After you’ve done this, select a point that has an older date than the one in which you first started to notice the error.
- Click Next to advance to the next menu.
- Click Finish and confirm at the final prompt.
At the next system startup, your older computer state will be enforced.
If the issue is still unresolved, move to the next solution.
7] Perform a Fresh Start, In-place upgrade repair or Cloud Reset
At this point, if the no security providers for antivirus, firewall, and web protection issue is still unresolved, it’s most likely due to some kind of system corruption that cannot be resolved conventionally. In this case, you can try Fresh Start, In-place upgrade or Repair to reset every Windows component. You can try Cloud Reset and see if that helps.
Hopefully, any of these solutions will work for you!
