![]() ![]() Starting with Cloud protection, I turn this on with the High protection level and an extended timeout of 50 seconds. If you’d like to use my personal configuration as a starting point, the next few screenshots provide each setting grouped by category. The usual guidance is to configure these settings as dictated by your organization/security team. Once you click Create and provide a name for your policy, you’ll see a list of options for configuring Microsoft Defender: Microsoft Defender Antivirus Configuration settings Microsoft Defender Security Center no subscription screen ![]() Then, select Windows 10 and later and Microsoft Defender Antivirus from the dropdowns. First, open the MEM portal and select Endpoint security > Antivirus > + Create Policy: Create a Microsoft Defender Antivirus policy Let’s jump to configuring Microsoft Defender Antivirus. It’s just that if you want advanced analytics and all of the goodies that MDfE has, you need MDfE. And if you don’t configure Microsoft Defender Antivirus, it is still native to the system and will still be default to enabled. So if you’re looking to use Intune to configure Microsoft Defender Antivirus and you don’t have a license for MDfE, you can absolutely do that. But Microsoft Defender Antivirus can also be used independent of MDfE. It sends data to Microsoft Defender for Endpoint for antivirus signals, threat analytics, gathering details about blocked malware, and more ( which you can read about here). For our purposes here is all you need to know – Microsoft Defender Antivirus is the Next-generation protection pillar. Start on this docs article if you have a few hours. There’s a lot to unpack here, and certainly worth it’s own blog post. Microsoft Defender for Endpoint is Microsoft’s Threat Protection solution that centers around 6 pillars – Threat & Vulnerability Management, Attack Surface Reduction, Next-generation protection, Endpoint detection and response, Automated investigation and remediation, and Microsoft Threat Experts. But since it is a component of Microsoft Defender for Endpoint (MDfE), if you’re using MDfE you get additional functionality. It doesn’t require a client to be installed or deployed, Defender is entirely built in. As you may know, Microsoft Defender is built in to Windows 10 and provides native antivirus functionality. I personally think those sentences are incredibly confusing, which is part of the reason I’m writing this blog post now. But Microsoft Defender Antivirus does not require Microsoft Defender for Endpoint. This can also happen when alongside Defender another real-time protection is installed in the system.Microsoft Defender Antivirus is a component of Microsoft Defender for Endpoint, previously Microsoft Defender Advanced Threat Protection. ![]() In this case, the file cannot be removed until the calling process is active. ![]() In my case, it never happened that Defender failed to quarantine or remove the downloaded file after it was detected and the action was chosen.Īnother situation can happen when Defender detects the file which is actually used by another process (legal or malicious). In some cases, the remediation can take a few minutes. Next, Defender usually asks about what action should be taken. It is detected on execution or when it is directly accessed. The same file but downloaded by Firefox (especially files in archives) does not trigger any alert from Defender (the file is not scanned). If the file is not checked by SmartScreen (usually an archive), then after the download Defender shows an alert about the detected threat. When I download a malicious file via Edge, the download is usually blocked by SmartScreen. From my experience with malicious downloads, Defender works differently with Edge (Chrome) and Firefox. ![]()
