Microsoft Windows Defender Review

Due to its name, there have been great expectations as to the effectiveness of Microsoft Windows Defender. Formerly known as GIANT AntiSpyware, the company acquired by Microsoft used to be a leader in online protection and the future after this merge seemed promising. Nevertheless, the truth is that there is a lot of complaining as to the lack of proper protection deriving from the installation of this security software. Below, we are going to analyze all the aspects of this security option in our detailed review of Microsoft Windows Defender. In this way, we will be able to conclude as to why we should or should not bother with this solution online.


Microsoft Defender for Windows 8, as well as all prior versions of Windows, is available online for download. If you have not already been using the built-in antispyware component on Windows, you can find it on and have it running for you in no time. As for special features, this software does not have any to boast of.

Instead, there is a simple and straightforward option for all the software users to comply with and get the coverage against malware and other online threats automatically. In the Windows 8 version, Microsoft Windows Defender was upgraded to a proper antivirus solution that does not leave anything to chance and requires no extra assistance from other tools.

Installation and Interface

As stated above, there is nothing complicated about the procedure of installing Microsoft free Windows Defender. You click on the button that launches the download and, once you are done, it begins the installation on its own. From then on, you find yourself with the software ready to offer its benefits to you. All users are able to pull the installation through, regardless of their knowledge in computing.

This can be really beneficial to people who are not accustomed to complex systems and software options. The interface of the software is basic and does not allow you to do much, though. In fact, you may find it difficult to update when needed and of course there are problems when trying to uninstall the software.

Help and Support

Microsoft is a true giant as a company and this is highlighted in the options that it provides regarding help and support. According to the issue you come across, you can browse through the categories of products and services at the official website of Microsoft or get to read through the blog, the newsletter or even the product guide.

Additionally to the community solutions available within your reach, you can also seek help from professionals via email, live chat and phone. So, overall there are many different things that you can look forward to in the field of help and support given by Microsoft. This is certainly the highlight of this software!

Overall Protection

The fundamental issue that needs to be tackled by any online protection software has to do with its capacity to offer thorough protection. This is where Microsoft Windows Defender does not live up to the security standards and thus fails to inspire people to try it out. In specific, AV-TEST reveals that there has been significant percentage of malware left undetected during testing and we have verified that, too.

On the bright side, the performance impact resulting from the use of the software is minor and therefore you will be expected to have minimal if any deterioration in the performance of your computer. Still, there is not much stability in the real-time protection promising to offer to the Internet users. So, rather than a complete solution in online protection, Microsoft Windows Defender should be considered as a valuable tool working in combination with other tools for malware detection.

Supportable Platforms

As its name suggests, Microsoft Free Windows Defender is suitable for Windows, exclusively. Windows XP, Vista and 2003 are compatible with its use, as well as Windows 7 and 8. It used to be a built-in antispyware component for computers running on Windows and it has been upgraded to autonomous anti-virus software for the very same computers. If you are using any other OS, it goes without even saying that you ought to look somewhere else for online protection.

Pros in a nutshell:

  • Easy to Setup and Use
  • Free of Charge
  • Low Performance Impact

Cons in a nutshell:

  • Basic Features
  • Problems with Malware Detection
  • Unreliable

Bottom Line

Even though Microsoft has proven its value over time, our review cannot end with us recommending the use of this software as a complete system of online protection. There are severe weaknesses in the detection of malware, which leads us to conclude that Microsoft Windows Defender is rather unreliable to use. It is light to activate and it will not slow your computer down. As a result, it can be used in combination with other tools and it is perfectly fine, since it does not cost anything to download and install. Nevertheless, it has not proven its value in keeping online threats at bay so far.
