Antivirus software is an essential tool that protects your computer from various threats such as viruses, malware, spyware, and other malicious software. Windows Defender is a built-in antivirus software that comes with Windows operating system. In this article, we will discuss what Windows Defender is and how it works.
What is Windows Defender?
Windows Defender is an antivirus software developed by Microsoft that provides real-time protection against various threats. It is a built-in feature of Windows operating system and comes pre-installed in Windows 10. Windows Defender was previously known as Microsoft Security Essentials and was available as a separate download for earlier versions of Windows.
How does Windows Defender work?
Windows Defender uses a combination of signature-based detection, behavioral analysis, and machine learning to detect and remove various threats. Signature-based detection compares the virus signatures with the database of known threats to identify and remove them. Behavioral analysis monitors the behavior of software and identifies suspicious activities. Machine learning uses artificial intelligence to analyze patterns and identify new threats.
Is Windows Defender enough?

In such cases, users can opt for third-party antivirus software that provides additional features and better protection.
