However, despite its convenience and somewhat acceptable protection capabilities, Microsoft Defender is lacking in some departments, and users are still left to fend for themselves when it comes to certain online threat-related situations. The fact that Windows Defender comes built-in and completely free for all Windows devices also adds to the universal appeal of the antivirus software. It is a convenient antivirus solution for Windows users and has a bunch of security features centered around device and online protection from spyware, adware, ransomware, and other malware. It was previously known as Windows Defender until the 10th of May, 2020, and now also appears as Windows Security in the newest Windows 10 updates.

It uses the same detection engine and malware definitions as Microsoft Security Essentials and Microsoft Forefront Endpoint Protection. However, it can be run on a computer that already has an antivirus product without any potential interference, and can therefore be used to scan a potentially infected computer as a second check from another antivirus program. It is not meant to be used as a day-to-day tool, as it does not provide real-time protection against viruses, cannot update its virus definitions and expires after ten days. It was released on 15 April 2011, following the discontinuation of Windows Live OneCare Safety Scanner. Microsoft Safety Scanner is a free disposable virus scanner similar to Windows Malicious Software Removal Tool that can be used to scan a system for computer viruses and other forms of malware.
