1] Run Windows Defender Troubleshooter

Most security alerts on your machine are fired off via Windows Defender or Windows Security. To effectively troubleshoot problems related to these apps, run the dedicated Windows Defender Troubleshooter. It will diagnose and often repair common problems that may have been degrading their ability to work properly or make spurious notifications.

To open the troubleshooter:

1. Open Get Help.

2. Type "troubleshoot windows defender" in the search box.

3. This will open the troubleshooter. Just follow the on-screen instructions to finish the process of troubleshooting.

Run this troubleshooter to identify quickly if the security notifications you see are really related to Windows Defender or Windows Security, or if there is a problem somewhere else.

2] Restart Windows Defender Firewall service

If you continue to get Windows Defender Firewall notifications about suspicious network activity, then you might have to restart the Windows Defender Firewall Service. To do so:

1. Press the Windows key + R.

2. Type in "services.msc" and press Enter.

2. In the "Services" window, scroll down to the service "Windows Defender Firewall". Double-click on it.

3. Click "Stop," then "Start."

4. Click "Apply" and "OK".

This step will help fix problems in case your firewall is behaving strangely.

3] Restart Windows Defender Advanced Threat Protection Service

This is one of the most important services that show many notifications regarding your computer's service. That is why we are suggesting you to restart this service too. Follow these steps if you want to restart the Windows Defender Advanced Threat Protection Service:

• Open Services panel.

• Double click on Windows Defender Advanced Threat Protection Service.

• Click the Stop button.

• Click on the Start button.

• Click on Apply and OK.

4] Disable the highest privilege of Windows Defender Scheduled Scan

This can be further minimized by changing the priority and power settings of WD's scheduled scan. Here's how:

1. Open Task Scheduler.

2. Go to Task Scheduler Library > Microsoft > Windows > Windows Defender.

3. Double-click "Windows Defender Scheduled Scan."

4. Turn off "Run with highest privileges" to make it less resource-hungry on the system.

5. Go to the "Conditions" tab.

6. Clear the "Start the task only if the computer is on AC power" checkbox to Enable Scan with battery power.

7. Click "OK" and your changes will be saved and closed.

Note: Though the following steps may be used to reduce the impact of the scan, turning it completely off is not at all advisable since it may leave an open vulnerability to your system.

Key improvements :

 • Language has been made clearer and more concise.

 • A warning against complete disabling of the scan was added.

 • Changed goal from fully disable to reduce impact.

• More descriptive terms were provided, such as "lower priority" and "adjust power settings."

5] Disable/Remove third-party security software

To ensure smooth performance and avoid potential conflicts while running the parental control software or other applications, it is preferable to disable any third-party security applications running on your PC. If problems persist, then install a different security application that will be more suitable to your needs than your currently used application.
