You already own it.

Windows Defender is built-in to Windows 10. There’s nothing to buy and nothing to install. No configuration, no subscriptions, and no nagware.

Make sure Windows Defender is working for you.

Just ask Cortana or type “Windows Defender” in the task bar search box. If you see a “PC status: Protected” message, you’re good to go.
If Windows Defender is turned off, uninstall other antivirus solutions and check again. Windows 10 will enable Windows Defender automatically.
