### 🛡️ How to Disable or Uninstall Antivirus Software

Removing antivirus software will make your system more vulnerable to malware, viruses, and other threats. Only do this if you have a good reason (e.g., testing, gaming performance, or using your own security setup).

***

### 🛡️ Step 1: Identify Your Antivirus Software

| Antivirus                           | Common Source                                  |
| ----------------------------------- | ---------------------------------------------- |
| **Windows Defender**                | Built into Windows                             |
| **Avast / AVG**                     | Free/paid AV software                          |
| **McAfee**                          | Often pre-installed on PCs                     |
| **Norton / Symantec**               | Subscription-based AV                          |
| **Bitdefender**                     | Paid AV with system control                    |
| **Kaspersky**                       | Strong security, controversial in some regions |
| **Trend Micro, ESET, Sophos, etc.** | Less common, but still effective               |

To check:

* Press `Windows + R`, type `appwiz.cpl`, and press Enter to view all installed programs.
* Also check the **System Tray** (bottom-right of screen) for icons.
* Open **Task Manager > Startup tab** to spot antivirus-related items.

***

### 🛡️ Step 2: Uninstall Third-Party Antivirus Software

1. Press `Windows + R`, type `appwiz.cpl`, and press Enter.
2. Locate any of the following (examples):
   * **Avast Antivirus**
   * **McAfee LiveSafe**
   * **Norton Security**
   * **Bitdefender**
   * **AVG Antivirus**
   * **Kaspersky**
3. Select each one, then click **Uninstall**.
4. Follow the uninstaller’s instructions — some may require a reboot.
5. Repeat this for all antivirus software found.

### 🛡️ Step 3: Disable Windows Defender (Microsoft Defender Antivirus)

{% hint style="warning" %}
Microsoft Defender automatically reactivates if no other antivirus is installed. You’ll need to disable it manually if you want **zero antivirus** on the system.
{% endhint %}

**Option 1: Disable via Windows Security Settings**

1. Press `Windows + I` → **Privacy & Security** → **Windows Security** → **Virus & threat protection**.
2. Under **Virus & threat protection settings**, click **Manage settings**.
3. Turn **Real-time protection** to **Off**.
4. (Optional) Disable **Cloud-delivered protection** and **Tamper Protection**.

**Option 2: Disable via Group Policy (Windows Pro)**

1. Press `Windows + R`, type `gpedit.msc`, and press Enter.
2. Navigate to:

   Copy

   ```
   Computer Configuration → Administrative Templates → Windows Components → Microsoft Defender Antivirus
   ```
3. Double-click **Turn off Microsoft Defender Antivirus**.
4. Set it to **Enabled** → Click **OK**.
5. Restart your PC.

**Option 3: Disable via Registry Editor (Any Windows Edition)**

> ⚠️ Use with caution.

1. Press `Windows + R`, type `regedit`, press Enter.
2. Navigate to:

   Copy

   ```
   HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender
   ```
3. Right-click in the right pane → **New > DWORD (32-bit)** → Name it `DisableAntiSpyware`.
4. Set its value to `1`.
5. Reboot your PC.

***

### 🛡️ Step 4: Confirm Everything Is Disabled

1. Press `Ctrl + Shift + Esc` to open Task Manager.
2. Check the **Processes** and **Startup** tabs for any antivirus-related tasks.
3. Open **Windows Security** again to verify Defender status.
4. You can also use `msinfo32` → Look under **System Summary** → Look for any mention of active AV.
