This article is about turning on Windows Defender antivirus (or Microsoft Security Essentials for the older Windows 7 and Vista OS) in order to help protect your computer from malware and spyware. This is a free, built-in software program from Microsoft that is often overlooked because users usually install other third-party antimalware programs on their computers like Avast, Bitdefender, McAfee, etc.

The first thing you should try is to restart the service that Windows uses to keep the tool active. You can do this by opening Run and looking for the Security Center service, then right-clicking it and selecting Restart.

If this doesn’t work, you can try to turn on Windows Defender by opening your settings and selecting Virus & threat protection. Open this and toggle the switches for real-time protection and cloud-delivered protection on. These are the only two options that guarantee that Defender will be turned on. If these don’t work, you may need to reset the app.

If your computer isn’t currently protected against malware, the first step to take is to turn on Defender. This can be done by typing “action” into the search function, and clicking either the spyware or virus protection option from the results page.

Once Defender is activated, real-time protection will scan and monitor your system. When it detects anything that could be malicious, you’ll be notified and given the choice to allow it or move it to quarantine.

You can also enable Network Inspection System, which sends samples of any detected malware to Microsoft for analysis. You can also select whether or not to join Microsoft’s Malware Protection Center (MAPS), which will send basic information about any malware detected on your system, such as where it came from and how you dealt with it. This isn’t a requirement, but it’s an optional feature that many people choose to use. It’s important to note that Windows Defender may not be able to detect and prevent all forms of malware, so it’s best used in conjunction with other security measures.
