Should I turn on Windows Defender?
Now, it’s a fully integrated part ofWindows 10.
What Is Windows Defender?
Windows Defender offers real-time protection against various threats, such as adware,spyware, andviruses.
The system can help protect your box from many rogue programs online and those inadvertently downloaded via email.
(In Windows 8 or 7, look inControl Panel>System and Security.)

This area contains the controls to run malware scans and at-a-glance status reports for your PC.
Defender updates automatically, but updating the program yourself is always a good idea before running a manual scan.
Still, running a full scan every month or so is a good idea.

This is a basic, no-nonsense security product, so added features such as scan scheduling are not available.
The Anniversary Update for Windows 10, however, added enhanced notifications, which provide periodic status updates.
Still, it’s not considered the best option for PC security.
Windows Defender, by comparison, needs only to be activated to provide adequate protection for your PC.
