Windows defender is the default antivirus installed in Windows 10 to safeguard your PC from any virus and free from any malware. It’s just like Microsoft Security Essentials solutions in Windows 7 and previous versions.
Windows Defender in Windows 10 features
In Windows 7 and previous versions the Windows defender was just a spyware remover how however in Windows 10 it has seen a major update and it now deals with viruses, malware and spyware as well. Now a scan option is also available where users can quickly scan their files and folder as well.
The Windows defender by default settings automatically downloads and updates the software from Microsoft servers without any user interference. However if you have disabled automatic update, you have to do that process manually.

Now download either 32-bit or 64-bit depending on your Windows.
The update file will be named as mpas-fe.exe, mpam-fe.exe, or mpam-feX64.exe.

If your Windows 10 is offline and you’re using Windows Defender instead of third-party tools, we recommend you update the Defender at least three days once if not possible to update every day.
