Windows operating system is far more prone to malware than other operating systems present. It can become fragile in terms of security. Various reasons for that are not only that it is commonly used, but it has a Windows registry that stores configuration settings. Any change in the Windows Registry can tweak the behavior of your operating system and any change in that can lead to corruption. A normal user may not have much idea about the internal mechanism and may put the OS and System at risk of being exploited.

Despite dominating the OS market share, this antivirus solution has much less market share than the existing providers of the market. Microsoft comes with multiple features that you can use to keep your operating system secure. Does it secure everything? well, let’s walk through some of the potential features it covers, first.

Microsoft has tailored the features of Windows Defender according to what they feel would secure their native OS. There can be various ways the malware attack can happen to your PC, let it be phishing email third-party site downloads, or even an insecure app. The real-time protection of Windows Defender is indeed a standout attribute. I ran a few tests on a Windows 10 with Windows Defender on. The results were pretty impressive, especially the Real-Time protection feature. While it did a great job finding the intrusion file, it would still be incomplete to say it is all that you need.

I figured the best use case for Windows Defender is using it with a known Antimalware present in the market like Malwarebytes or Macafee. A combination of Windows Defender with known Antivirus can drastically improve the security of your PC. Windows Defender is best when your device does not have much sensitive content in it. If you do have some files or information that you can’t risk, you should use a combination of market-present antimalware along with Windows Defender.
