Note: Windows Defender is now called Microsoft Defender Antivirus. Initially a downloadable free anti-spyware program, it has now evolved into a full antivirus program that is a built-in for Windows 8 and Windows 10

Windows Defender protects the computer against viruses, spyware and other malware. It is equivalent to Microsoft Essentials and offers real time protection against potential threats. Its execution does not slow down the PC nor impact on its general performance.

Key Features

Defense against spyware and malware

Windows Defender is able to recognize almost all potential spyware and malicious programs that try to infect the computer's system. Once it detects one of them, this program automatically blocks it.


In order to check up the integrity of Windows system and ensure that there is no infection, this antivirus can perform a thorough scan of the hard drives from the simplest document folder to the bottom of the registry keys.


As soon as Windows Defender finished analyzing the PC system, it offers the ability to purge all malicious items. This action can be performed easily with a single mouse click via the option called "Clean System".


This utility is provided with a large database where a great number of known threats are listed. Every time, the computer is connected to Internet, this base is updated so as to integrate latest malwares.

Is It Free?

Windows Defender is downloadable for free.

Alternative spelling: WindowsDefender1593.msi
