Журнал защиты — это часть приложения «Безопасность Windows», в котором отображаются действия и рекомендации по угрозам в Windows 11 и 10. На странице представлены элементы, помещенные в карантин, элементы, удаленные, удаленные элементы, разрешенные элементы, удаленные элементы, заблокированные действия и серьезность угрозы. Параметр «Заблокированные действия» имеет 3 подменю: «Блокировать доступ к папке», «Заблокированные элементы» и «Блокировать на основе правил». Точно так же параметр «Серьезность» имеет 4 элемента: «Тяжелая высокая», «Умеренная» и «Низкая». Но иногда люди жалуются на отсутствие истории защиты.
История защиты Защитника Windows пуста или пуста, и на странице ничего не видно, когда возникает проблема. Сразу после запуска «Быстрого сканирования», «Полного сканирования», «Выборочного сканирования» или «Автономного сканирования Microsoft Defender» пользователь обычно переходит к истории защиты. Но он разочаровывается и обнаруживает себя из ниоткуда, когда оказывается незанятым, потому что он не может узнать статус угроз или устранить их на своем компьютере с Windows 11. К счастью, есть решения этой проблемы. См. — Исправление: пустые, пустые или отсутствующие параметры программы предварительной оценки в Windows 10.
Вот как исправить историю защиты, отсутствующую в Windows 11 или 10 —

Вот и все!!
Подобно другим антивирусам, встроенный Защитник Windows ведет историю обнаруженных угроз, просмотреть которую можно в журнале защиты. Эти записи будут отображаться в журнале, даже если опасный файл обезврежен и помещен в карантин, что может вызвать своеобразный побочный эффект, проявляющийся наличием красного или желтого значка на иконке Защитника в системном лотке. в Windows 10 2004 разработчики вроде бы должны были решить эту проблему.
Но, судя по отзывам пользователей, сталкиваться с ней приходится и в последней стабильной версии системы.
Чтобы избавиться от этих предупреждающих о несуществующей уже угрозе значков, нужно очистить журнал Windows Defender. В сборках до релиза 1903 сделать это можно было через интерфейс управления безопасностью Windows, в более поздних сборках системы кнопка очистки журнала отсутствует. Данные журнала удаляются автоматически по истечении 30-и дней, но вы можете сократить этот период или просто удалить их принудительно.
Изменение срока хранения Журнала Защитника
Для изменения срока хранения записей в журнале Защитника Windows 10 мы предлагаем использовать консоль PowerShell.
Запустив ее от имени администратора, выполните в ней команду Get-MpPreference и найдите в полученном списке параметр ScanPurgeItemsAfterDelay.
В Windows 10 2004 его значение равняется 15, то есть данные журнала хранятся 15 дней. Чтобы сократить этот срок, скажем, до двух дней, выполните в PowerShell такую команду:
Set-MpPreference -ScanPurgeItemsAfterDelay 2
Принудительная очистка Журнала Защитника
Если вы хотите очистить журнал прямо сейчас, выполните следующие действия.
Перейдите в Проводнике в папку C:\ProgramData\Microsoft\Windows Defender\Scans, а затем зайдите в расположенную в ней папку History, подтвердив вход с правами администратора.
В свою очередь, в ней найдите папку Service и удалите ее.
Вместе с ней будет удалена и история действий Windows Defender.
Должен исчезнуть и значок предупреждения на иконке Защитника. Однако, если у вас не настроены базовые функции безопасности, желтый значок предупреждения будет отображаться независимо от того, имеются в журнале записи или нет.

If a simple restart doesn’t help, you can reset Windows Security in seconds
Updated on September 10, 2022
Windows Defender not opening or working correctly could mean you can’t edit any of its settings in Windows Security, or malware can run amok on your system because you don’t have the proper security in place. Below are several reasons why Windows Defender doesn’t open and how to get it working again.
Why Windows Defender Won’t Open in Windows 11
Here are some examples of situations where Microsoft’s anti-malware app won’t open or work properly:
- There’s a temporary memory-related issue where the app won’t scan for malware.
- Windows Security opens normally, but then promptly closes a few seconds later.
- Another software program is «fighting» with Windows Defender, and it’s throwing error messages.
- You see an error that says, «You’ll need a new app to open this windowsdefender link.»
- You recently installed or uninstalled another virus protection program, and now Windows Defender won’t open.
Windows Defender is called Microsoft Defender in Windows 11, and it’s managed through Windows Security. These names are used interchangeably in this article, but we’re referring to the same tool.
How to Fix Windows 11 Defender Not Working
There are several things you can try, but follow this list in the order it’s presented to address the easier solutions first:
-
Restart your computer. This is a very common first step when troubleshooting basically anything in Windows, and it might just be all you have to do to get Windows Defender working again.
-
Turn off Windows Defender, and then turn it back on. Or, if it was off to begin with, that article shows you how to turn it on.
Microsoft Defender won’t catch active malware unless you have Real-time protection turned on.
This step is useful if, in your situation, «Windows Defender not working» simply means that it isn’t checking for malware. If you can’t open Windows Security in Settings, then move on to the next step.
-
Repair or reset Windows Security. A repair will have Windows attempt to fix whatever is going on, and a reset will erase all the app’s settings and start over as if Windows Defender was just installed.
Follow that link for two methods—one uses Settings, like in the image below, and the other uses a PowerShell command that’s helpful if you can’t open Windows Security at all.
-
Update Windows. This is how Microsoft delivers bug fixes, so an update you’ve yet to install could address the Windows Security issue.
If that doesn’t work, you can try an offline Microsoft Defender update. Choose the latest version from that list, likely called Update for Microsoft Defender Antivirus antimalware platform.
To avoid getting an update you don’t need, you can check your current version from Settings > Privacy & security > Windows Security > Open Windows Security > Settings > About.
-
This step is for when your problem is so specific the only issue you’re running into is you can’t seem to clear out the Protection history screen in Windows Security, or you’re told a threat was found, but there’s nothing to clear out.
To address this, open the following folder. One easy way to do this is to paste this path into the Run dialog box (WIN+R):
C:\ProgramData\Microsoft\Windows Defender\Scans\History\Service\
Select everything in the Service folder (Ctrl+A), and then press Delete to clear it out.
-
Temporarily disable any other antivirus programs you have installed. How this works is different for every app, but doing so should give you some time to see if Windows Defender’s troubles were due to a compatibility issue with the other anti-malware tool.
If you find the other program is to blame, or you suspect it might be but disabling it didn’t help, use a program uninstaller tool to completely delete the software.
If you still can’t start Windows Defender, there are a couple of registry keys you can delete to re-enable it. This might happen after uninstalling another antivirus program.
Open this key, and delete these two registry values from there:
DisableSpyware and DisableAntivirus.HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender\
Your computer might not have these registry values, since they most likely exist only if security settings have been implemented via group policy (e.g., an IT department). If so, just move on to the next step.
-
Run the SFC /scannow command to repair system files. This will invoke the System File Checker tool to see if there are any problems with protected Windows files, and then replace them if so.
-
Use Reset This PC to reinstall Windows 11. Although this will reinstall Windows and reset all your programs back to their factory default state, that’s exactly what you want in this situation.
This is a sure fix for whatever problem is affecting Windows Defender, just make sure you wait until you’ve tried all the above before completing this drastic step.
Choose carefully to keep or wipe your data when resetting your PC.
FAQ
