One of the most common behaviors of Windows Defender is that if it detects third-party antivirus software, Windows Defender will automatically shut down. Windows is designed to detect the presence of installed security software, and we often see the notification in the Action Center. One of the common problems we’ve encountered in the past is when I am more security software installed. They often create conflict with each other and ultimately create more problems than doing good. Frequent freezing and crashing of applications are some of the common problems that occur when installing more than one antivirus software.

So, to avoid this situation, Windows Defender will automatically shut down when it detects another security program. Likewise, if this security application has a firewall, Windows Firewall will also stop working. So in case you want Windows Defender to work, you will need to uninstall the third party security software and reboot the system. Users often don’t know if the security software is actually installed or not because when buying a new laptop, it mostly comes with a trial version of the security software like Norton, McAfee, etc. So, when installing applications like Flash or Java, it may ask you to uninstall the free security scanner when most of them don’t notice.

So it is better to search your PC if you are unsure whether the security software is installed or not. Once removed, you may need to activate Windows Defender manually. Type “Windows Defender”In the search box and then press Enter. Click Settings and make sure there is a check mark on Enable real-time protection. In Windows 10, open Windows Security> Virus Protection and turn on the switch Real-time protection in the On position.
