How to check if Microsoft Defender is enabled in Windows

The security of our computer is one of the most important issues today. With online threats increasing every day, it is essential to have active protection on our computer. Windows has a built-in protection program, the Microsoft Defender, which protects us from viruses and malware without having to install anything extra.

Why is it important? Many times Microsoft Defender can be disabled accidentally or by other programs, leaving your computer at risk. That's why it's a good idea to regularly check if it's working properly.

In this article, we will show you the simplest ways to check if Microsoft Defender is protecting your computer. The methods we will present are understandable even for novice users, and you do not need any special knowledge to follow them.

🔍 Method 1: Check from Windows Settings

This is the easiest way to see if the protection program is active:

1. Press the keys at the same time Win + I on your keyboard
2. The Settings window will open. Find and click on the option "Information and Security"
3. From the menu on the left, select "Windows Security"
4. Click on "Protection from viruses and threats"
5. If everything is OK, you will see the message "Your device is protected"

Advice: If you see red warnings or messages that something is wrong, then the protection program may be disabled.

🛡️ Method 2: Direct check from Windows Security

Windows Security is the control center for all security issues:

1. Click the button Start (the Windows logo)
2. Type "Windows Security" and press Enter
3. The security program will open. Click on "Protection from viruses and threats"
4. Check the status of Microsoft Defender - if it is active you will see a green check mark

Caution: If you see yellow or red indicators, it means there is a problem that needs immediate attention.

⚙️ Method 3: Check via Task Manager

This way shows you if the program is running in the background:

1. Press simultaneously Ctrl + Shift + Esc to open Task Manager
2. Click the tab "Services"
3. Search the list for the service with the name "WinDefend"
4. If you see the word next to it "Running", then Defender works normally

💻 Method 4: Advanced Check (PowerShell)

If you are a more experienced user, you can use PowerShell:

1. Click Win + X and select "Windows PowerShell (Admin)"
2. Type the following command:

Get-MpPreference

In the results, look for the line "RealTimeProtectionEnabled":

• If you see "True" - Defender is active
• If you see "False" - Defender is disabled

🔧 What to do if Microsoft Defender is disabled

If you find that the protection program is not working, try the following solutions:

Check for other security programs:
Many times other antivirus programs automatically disable Microsoft Defender. Check if you have another security program installed.

Activation from Settings:
Go to Settings → Windows Security → Virus & threat protection → Manage settings, and enable "Real-time protection".

Using PowerShell to enable:
Open PowerShell as administrator and run:

Set-MpPreference -DisableRealtimeMonitoring 0

Restart the computer:
Sometimes a simple restart can solve the problem.
