Windows® Defender definitions are actually files that act like a database of known spyware and other potentially unwanted software. Because Internet threats and dangerous programs are constantly developed, Windows® Defender relies on up-to-date definitions to determine if software that's trying to install itself to your computer is spyware or potentially unwanted software. Windows® Defender works with your Windows® Update settings to automatically install the latest definitions. Using this article, you will learn how to check if the database update is correctly set up.
Checking Windows® Defender definitions setting:
- Open the Start menu and click on the “Control Panel” button.
- In the search box, type “Defender”. Then, click on Windows® Defender in the list of results.
- In the main navigation bar, click on the “Tools” button and then on the “Options” button.
- Automatic update - Select “Automatic scanning” in the left pane. Set the automatic scan time and be sure that the “Check for updated definitions before scanning” checkbox is checked. This is how you can be sure that you have regularly updated the database and checked the computer.
