Updating Microsoft Defender

Microsoft Defender is a powerful malware protection tool that helps protect your computer from malicious software, such as viruses, spyware, and rootkits. It is important to keep your Microsoft Defender up to date to ensure the highest level of protection against new threats. This article will provide you with step by step instructions on how to update Microsoft Defender.

Checking for Updates

The first step in updating Microsoft Defender is to check for new updates. To do this, open the Start menu and type “Windows Security.” Then click on the “Windows Security” icon to open the Windows Security window. In the Windows Security window, click on the “Virus & threat protection” option. On the left side of the window, you will see the “Check for updates” option. Click on that option and Microsoft Defender will start checking for updates.

Installing Updates

Once Microsoft Defender has finished searching for updates, it will display a list of available updates. Select the updates you want to install and click “Install.” Microsoft Defender will begin downloading and installing the selected updates. Depending on the size of the updates, this process may take some time.

Scanning for Malware

Once all of the updates have been installed, Microsoft Defender will prompt you to scan your system for malware. It is recommended that you perform a full system scan to ensure that all potential threats are detected and removed. To start the scan, click on the “Scan now” button. Depending on the size of your system, the scan can take a while to complete.

Advanced Protection Features

Microsoft Defender also provides advanced protection features, such as real-time protection, cloud-based protection, and automatic sample submission. To enable these features, click on the “Advanced options” button in the Windows Security window. Then select the “Advanced” tab and check the boxes next to the desired options.

Setting Exclusions

If you have certain files or folders that you want Microsoft Defender to ignore, you can set exclusions for those items. To do this, click on the “Exclusions” option in the Windows Security window. Then select the files or folders that you want to exclude from the scan and click “Add.”

Configuring Notifications

You can also configure how Microsoft Defender notifies you of potential threats. To do this, click on the “Notifications” option in the Windows Security window. Then select the type of notification you want to receive and click “Apply” to save your changes.

Managing Quarantined Items

If Microsoft Defender detects a potential threat, it will place the item in quarantine. To view and manage the items in quarantine, click on the “Quarantine” option in the Windows Security window. From here, you can view the items that have been quarantined, restore them, or delete them.

Managing Exclusions

You can also manage the items that you have excluded from the scan. To do this, click on the “Exclusions” option in the Windows Security window. From here, you can view the items that have been excluded, add new items, or remove existing items.

Using the Windows Security App

Microsoft Defender also provides a Windows Security app that you can use to manage and update your security settings. To open the app, click on the “Windows Security” icon in the Start menu. From here, you can view your protection status, update your security settings, and manage your quarantine items.
