It sounds like your Mac might be infected with malware that is mimicking Windows Defender and causing issues at startup. Here's how you can remove it:
### 1. **Boot into Safe Mode**
- **How to Do It**: Shut down your Mac. Turn it on and immediately press and hold the **Shift** key. Release the Shift key when you see the Apple logo and a loading bar.
- **Why This Helps**: Safe Mode only loads essential system files and can prevent the malware from running, giving you a chance to remove it.
### 2. **Check for Suspicious Applications**
- **How to Do It**: Once in Safe Mode, go to **Applications** > **Utilities** > **Activity Monitor**. Look for any unfamiliar or suspicious processes running. If you find any, select them and click the "X" button to force quit.
- Next, go to **Applications** and **System Preferences** > **Users & Groups** > **Login Items**. Remove any suspicious items from the list of applications that launch at startup.
- **Why This Helps**: Removing or disabling suspicious applications and login items can prevent the malware from activating.
### 3. **Delete the Malware Files**
- **How to Do It**: Go to your **Applications** folder and look for any apps that you don’t recognize or that might be related to the fake Windows Defender. Drag them to the Trash. Also, check the **~/Library/LaunchAgents/** and **/Library/LaunchDaemons/** folders for any suspicious files or scripts and remove them.
- **Why This Helps**: Malware often installs files in these locations to run automatically. Deleting these files can help stop it from launching.
### 4. **Run a Malware Scan**
- **How to Do It**: Download a reputable anti-malware tool designed for Mac, such as Malwarebytes for Mac. Install the software, run a full system scan, and follow the prompts to remove any detected threats.
- **Why This Helps**: A dedicated anti-malware tool can identify and remove malware that might be hidden in various parts of your system.
### 5. **Reset Browser Settings**
- **How to Do It**: If your browser has been affected, reset it to default settings. In Safari, go to **Safari** > **Settings** > **Privacy** and click on **Manage Website Data...** to remove all stored data. In Chrome, go to **Settings** > **Reset Settings**.
- **Why This Helps**: Malware can sometimes hijack your browser. Resetting it can clear any malicious extensions or settings changes.
### 6. **Update macOS**
- **How to Do It**: Go to **System Settings** > **General** > **Software Update** and make sure your macOS is up to date.
- **Why This Helps**: Keeping your system updated ensures you have the latest security patches, which can help prevent future infections.
### 7. **Consider a Reinstallation of macOS**
- **How to Do It**: If the malware persists, you may need to reinstall macOS. You can do this by restarting your Mac in **Recovery Mode** (press Command + R at startup) and selecting "Reinstall macOS" from the options. Make sure you have a backup of your data before doing this.
- **Why This Helps**: Reinstalling macOS can remove deeply embedded malware, though it should be a last resort.
If you're unable to remove the malware using these steps or feel uncomfortable doing so, consider taking your Mac to an Apple Store or authorized service provider for professional help.
