Microsoft Windows Defender Antivirus for Windows 10

Who doesn’t know Microsoft Windows Defender Antivirus? Every copy of Windows has this piece of software (formerly known as Microsoft Security Essential). But interestingly enough, a lot of people are not sure or never actually used this antivirus. There is a certain myth or sentiment that believes that any Windows built-in software are bad. We believe that this myth started from Internet Explorer being infamously slow and unreliable. People often said that once you install Windows, the first thing you do is get a browser to replace Internet Explorer. But, is that the same case with Microsoft Windows Defender? We believe that if you answer ‘yes’ than you’re wrong.

Windows Defender got its name since Windows 8.1 and still the same until Windows 10. It was released as a downloadable free antispyware program for Windows XP and was later shipped with Windows Vista and Windows 7. And then it became a full antivirus program in Windows 8. So, now we know why it received such a bad reputation in its earlier phase. Since before the name change in Windows 7, Windows Defender received a lot of serious updates that increase its reliability and performance as antivirus software. Especially in 2019, this antivirus has risen to be on the list of best free antiviruses in the world. Despite its improvements, Microsoft wants to make users who want a third-party antivirus install their software of choice with no problems. Windows Defender will switch itself off when a third-party antivirus installation is detected.

In Windows 10, Windows Defender has its own set of dedicated settings in the Settings app. To make it more recognizable, Windows Defender is renamed to Windows Defender Antivirus and later removed in the Windows 10 April 2018 Update and transferred to Windows Defender Security Center.
