Follow the steps below to install Microsoft Defender on your devices. And yes, devices Important: This article is about the Microsoft Defender app that is included with Microsoft Family or Personal subscriptions.
If you're looking for information about the Microsoft Defender Antivirus that is built into Windows, see Stay protected with Windows Security. After installing, sign in with your personal Microsoft account such as outlook.
When you first sign into Microsoft Defender on Android, we'll walk you through a few easy steps that start with setting up web protection. During this process, we'll ask you to give Defender permission to do two things: run in the background and use the Accessibility Service. A security tool that only works sometimes isn't nearly as effective.
You want Microsoft Defender to always watch your back, protecting you from the malicious sites you weren't expecting. In order to do that, Defender needs permission to run in the background. In order to make sure the site you're going to isn't known to be dangerous, Defender needs to be able to see the address. To do that on Android, we use the Accessibility Service to read, almost literally, the address from your browser.
Important: Only one app at a time can have permission to use the Accessibility Service. If you give that permission to a different app, web protection in Defender will be turned off. After setting up web protection, we'll set up anti-malware protection. To do this we need to ask for a couple more permissions. Microsoft Defender scans apps and files on your device to watch for possible threats.
To do that, it needs to be able to access those files. We only use that permission to look for malicious apps, a process that happens entirely on your device. No information about your apps or files is sent to Microsoft. If you want Microsoft Defender to tell you if we find a threat, you'll need to allow us to send you notifications on your device. Note: If you already allowed Microsoft Defender to run in the background for web protection, you won't be asked for this permission again.
Protecting your device is a full-time job, but you probably want to use your device for other things, like texting, gaming, work, and entertainment.
By allowing Microsoft Defender to run in the background, you allow us to help keep you safer all the time. Finally, Microsoft Defender will run an initial scan of your device to see if there are threats already on it.
This scan usually only takes a minute or two. If that initial scan finds any threats Microsoft Defender will notify you and help you remove them. When you first sign into Microsoft Defender on iOS, we'll walk you through a few easy steps that to set up web protection.
During this process, we'll ask you to give Defender permission to do two things: set up a local virtual private network VPN and allow notifications.
Due to the built-in security settings in iOS, other apps aren't able to see the address URL an app is trying to open, including those being opened in the web browser. To make sure the site you're going to isn't known to be dangerous, Defender needs to be able to see the address.
To do that, we set up a local VPN. It's called a local VPN because it never leaves your device—it's just a connection between your browser and Microsoft Defender running on your device. When you click on a link, the browser sends the address you're going to through that local VPN to Defender. Defender checks the address and then assuming it's good , lets the browser open that site.
The whole thing happens so quickly you won't even notice. If the site is found to be malicious that's where notifications come in. We block access to the site, but iOS won't let us notify you of the problem in the browser, so instead we send you a notification telling you that the site you're trying to go to is dangerous.
From that notification you can close the browser tab and stay safe. Or, if you're completely sure that the site is safe, you can choose to continue to the site anyway. Important: You can choose not to allow notifications and web protection will still work, but you won't get the notification that it was Defender who blocked the site you were trying to go to. PKG installation file. When you first sign into Microsoft Defender on Mac, we'll will walk you through a few easy steps to set up anti-malware protection on your device.
During this process, we need you to give Microsoft Defender a couple of permissions so that it can protect you. To start with, we'll have you open the Security settings , then follow these steps:. Select the padlock at the bottom left so you can make changes. You'll be prompted to enter your password or other authentication.
You should see a prompt that says that Some system software requires your attention before it can be used. Select the Details button. Note: If you're using macOS Catalina Next, we'll need permission to access your files. Microsoft Defender scans apps and files looking for threats and it can only do that if it has permission to access the files.
We'll ask you to select Open Privacy Settings , then follow these steps:. Finally, Microsoft Defender will run an initial scan of your device to see if there are any threats already on it.
That scan may take a while—depending on the speed of your device and how many apps you have—but you can keep using your computer while the scan runs in the background.
Tip: If Microsoft Defender is successfully installed and running, you'll see its icon on the title bar near the clock at the top right. If you're part of a Microsoft Family subscription the last step is to decide if you'd like to share your security status with your family organizers.
The family organizer is the person who established the Microsoft Family subscription, and any other family members that person has selected to be family organizers. By sharing your security status, you make it easier for the family organizers to help keep your devices safe. This only shares security information from Defender, not any other information about your device or any of your personal data.

Is Microsoft Defender Good Enough? With Windows 8, the product was tidied up a bit, bundled with Windows, and renamed Windows Defender.
But Windows Defender boasts some advantages, too. Windows Defender also plays nicer with web browsers and other apps—respecting their security and privacy settings more than most other antivirus apps. What you use is up to you, but Windows Defender is not a bad choice and has overcome most of its problems from a few years back. We do, however, recommend running an anti-malware app like Malwarebytes in addition to whatever antivirus app you choose.
It will only pop up to inform you when it finds malware. Antivirus definition updates automatically arrive through Windows Update and are installed like any other system update. Here, you can see all the threats that Windows Defender has quarantined. To see more about a threat, click the arrow to its right. By default, Windows Defender automatically enables real-time protection, cloud-based protection, and sample submission.
Real-time protection ensures Windows Defender automatically finds malware by scanning your system in real time. You could disable this for a short period if necessary for performance reasons, but Windows Defender will automatically re-enable real-time protection to keep you safe later.
Cloud-based protection and sample submission allow Windows Defender to share information about threats and the actual malware files it detects with Microsoft. If antivirus is dramatically slowing down a certain app you know is safe by scanning it, creating an exclusion can speed things up again. If you use virtual machines, you might want to exclude those large files from the scanning process. Maybe You Should Use Exclusions.
Just be careful to use exclusions sparingly and smartly. Windows 10 automatically disables Windows Defender if you install another antivirus app. You can still use Windows Defender to perform a manual—or offline—scan as a backup to your preferred antivirus app, though. If you ever uninstall the other antivirus, Windows Defender will automatically kick into gear once again and take over, providing antivirus protection.
Do note, however, that certain anti-malware apps—like Malwarebytes—can be installed alongside Windows Defender and both will offer complimentary real-time protection. While it may not be perfect, Windows Defender does do a decent job, is minimally intrusive, and—when combined with other safe computing and browsing practices—might just be enough.
