What Are Some Features Of Microsoft Defender?
Additionally, many features come with the Microsoft Defender program, some of which include the following:
- Real-Time Protection – There are real-time protection options that come along with Microsoft defender. In a recent update, Limited Periodic Scanning was introduced and optionally allows Defender to scan a system periodically if another antivirus app is installed. Plus, it also introduced Block at First Sight, which uses machine learning to help predict whether a file is malicious.
- Browser Integration – Integration with Internet Explorer and Microsoft Edge enables files to be scanned as they are downloaded to detect malicious software that has been downloaded unknowingly. Furthermore, as of 2018, MS Defender is also available for Google Chrome via an extension and works alongside Google Safe Browsing.
- Application Guard – Defender Application Guard is a feature exclusive to MS Edge that was introduced in 2018. This prevents a malicious website or malware from affecting the system and the browser. Then, once installed, it will open your current tabs web page in MS Edge with Application Guard enabled.
- Controlled Folder Access – This feature was introduced with the Windows 10 Fall Creators Update to protect a user’s important files from the growing threat of ransomware. Additionally, Controlled Folder Access was released approximately a year later after the Petya family of ransomware first appeared. With it, you will be notified every time a program tries to access these folders and will be blocked unless given access by the user.
What Is The History Of Microsoft Defender?
Microsoft Defender wasn’t always the program we know today; it has undergone many name changes and adjustments over the years.
Furthermore, the Defender was initially based on GIANT AntiSpyware and was announced by Microsoft in 2004.
Additionally, the first beta release of Microsoft AntiSpyware was in 2005 and was a repackaged version of GIANT AntiSpyware.
Then, there were more modified builds released in 2005, with the last Beta 1 released in November of 2005.
At the 2005 RSA Security conference, Bill Gates, who is the Chief Software Architect and co-founder of Microsoft, announced that MS AntiSpyware would be made free to its users.
This was to ensure the security of their systems against the increasing malware threat.
In the same year, it was announced that Microsoft AntiSpyware was renamed Windows Defender.
Furthermore, beta 2 of this program was released in February of 2006, and it featured not only the program’s new name but also a redesigned user interface.
Additionally, the core engine was rewritten, which improved the performance of the application.
Also, since Beta 2, the program works as a Windows service, unlike its earlier releases.
This enables the application to protect the system even when a user is not logged on.
Beta 2 also requires Windows Genuine Advantage validation.
Sadly, Windows Defender did not contain some of the tools found in the earlier versions of Microsoft AntiSpyware.
For instance, Microsoft removed the System Inoculation, Secure Shredder, and System Explorer tools found in MSAS as well as the Tracks Eraser tool.
In October 2006, Microsoft released its final version of Windows Defender. This version supports Windows XP and Windows Server 2003.
However, unlike the different betas, it doesn’t run on Windows 2000.
Therefore, some of the key differences from the beta versions are improved detection, redesigned user interface, and delivery of definition updates.
