Microsoft Windows defender
You haven't specified a Windows version, but Microsoft Defender Antivirus comes with Windows 10, Windows 11, and their corresponding Windows Server siblings. The AV is one of the best, if not the best. It is so good that r/techsupport has forbidden conversations over AVs. More on reddit.com

What is your operating system? If it is Win10 or Win11, Defender is already there. Defender has shipped with every OS since Windows 8 as the default security suite, much better than Essentials. I don't believe you're going to be able to install it, which is what the error message means. More on reddit.com

February 17, 2024Windows Defender Install?
What problem are you trying to solve here? If you have Norton on your PC, it is filling the role of Antivirus monitoring on your PC. If you'd rather have Microsoft Defender Antivirus, it's also installed (as a default component in Windows) on the PC. You'd have to uninstall Norton from Add/Remove programs if you prefer Defender.

(Behind the scenes Norton unregisters itself with Windows Security via a private API using WMIC and Microsoft Defender Antivirus goes from Automatic Disabled running mode into Active running mode) More on reddit.com
