Windows Defender 2018-2019 Latest Version Full Free Download

Introduction   

Windows Defender is the well-known security tool from Microsoft that protects your system and your data against spyware and other malicious applications. Formerly named “Microsoft Anti Spyware”, Windows Defender is included by default in the latest 3 Windows editions (Vista, 7 and 8) and can be downloaded and installed separately on Windows XP and Windows 2003.

In my opinion, Windows Defender is one of the best things offered by the latest Windows editions. Though it is neat, lightweight and easy-to-use, it is also really handy and reliable. I like a lot the fact that it maintains a history of detected suspicious system activities and potentially malicious software, letting you review what actions have been taken regarding these detection. Furthermore, it provides 3 types of scanning (quick, full and custom) which can be scheduled to be automatically performed whenever you want. It also allows you to choose what actions you want Windows Defender to perform, by default, when it detects suspicious software (remove them, quarantine them, ignore and allow them).

The scan reports are comprehensive and thorough, providing loads of info about the detected items. Another handy feature is the fact that you can choose to exclude certain file types and locations from your computer from being scanned for malware by Windows Defender.

Windows Defender 2018-2019  

Microsoft added built-in security software to Windows for the first time. Since then, it’s appeared under various names, but currently it’s known as Windows Defender Security Center (WDSC). What started out as a basic antivirus detection feature has slowly grown into something that resembles a security suite. It doesn’t have anything close to the features you’d see in a third-party suite, but it does a fair job at antivirus and malware scanning.

The crucial section is Virus & threat protection. This is where you can manually start a full scan, enable real-time protection, or carry out an offline scan for removing particularly nasty bits of malware.

Device performance & health, meanwhile, just gives your PC a general health report card including Windows Update status, driver status, and so on. It does not report on any potential security weaknesses, short of lagging updates.

You can dive a little deeper into WDSC beyond this, but not by much. If I had to guess, Microsoft plans to expand its functionality over time, and right now we’re just seeing the basic scaffolding being built. That’s just speculation, however.

Performance 

Windows Defender stacks up alright in anti-virus detection. A-V Test gave Defender a 99 percent detection rate for real-world testing against 0-day, web, and email threats.  For run-of-the-mill malware, meanwhile, Defender scored very highly against more than 10,000 samples at 99.7 percent detection.

A-V Comparatives found a similarly high performance level for real-world protection, with about 9 false positives out of 329 test samples. SE Labs, for its part, gave Defender a AA overall rating in the period of April through June. (The highest that an antivirus can score with SE Labs is a AAA rating.) During its testing, Defender failed to protect against six targeted attacks and four web-based attacks.

As for the drain on your PC’s resources, that’s a little harder to measure than with third-party software. WDC is built right into the operating system and starts up automatically. To counteract that, we turned off the entirety of Windows Defender (both the scanning tool and the overall program) using the registry. Then we fired up our first benchmark: PC Mark 8’s Work Conventional benchmark, which simulates everyday tasks like video chatting, web browsing, and word processing, and recorded the score. Afterward, we switched   back on and started a full system scan before running PC Mark 8 again.

The results fell in line with the best third-party options: Windows Defender had no real effect on performance. Running Windows 10 with Defender off garnered a Park score of 2498. Once it was back on, the score went up to 2516—right within the margin of error for Park 8 results.

That story also held true in our mandrake performance benchmark, which puts far more strain on system resources. With Windows Defender turned off, we were able to transpose a 3.8 GB M K V file on the Android Tablet preset in one hour, 14 minutes, and 21 seconds. With Windows Defender turned on, it took one hour, 15 minutes, and 30 seconds. That difference is so small that it’s insignificant.

Conclusion  

Windows Defender is a fine basic security solution. For advanced users who are hyper-aware about all the various threats out there, this free option might be enough if they also periodically scan their systems with something like the free version of Malware bytes. The average user, however, should look for a more feature-rich third-party solution.

It always seemed strange to me that Microsoft let third-party software companies corner the market for protecting Windows from malware. I was personally excited when Microsoft acquired Sybarites Software’s antivirus products back in 2005 and remanded them as the Microsoft Forefront Security family of products. Then around 2012 Microsoft began releasing a series of announcements indicating they were ending further development of several Forefront products including Forefront Threat Management Gateway (which was a rebounding of Microsoft I SA Server, which was itself a reworking of the earlier Microsoft Proxy Server) and Microsoft Unified Access Gateway (which was based on a product originally acquired from Whale Communications). The only Forefront product that’s apparently still being developed is Forefront Identity Manager, but even that hasn’t seen a refresh since 2012.

Then the antivirus products Forefront Endpoint Protection and Forefront Client Security were moved from the Forefront Family to Microsoft’s System Center family of products and renamed as System Center Endpoint Protection, and this is still around, although now it’s under the System Center Configuration Manager umbrella. Then as if all that naming confusion wasn’t enough, Microsoft did an even better job of confusing the end-user market with their Windows Defender anti-malware product, which was initially released in 2006, then superseded in 2009 by Microsoft Security Essentials, then integrated into Windows 8 as Windows Defender, and then renamed as Windows Defender Security Center in Windows 10 Creators Update. I’ve actually lost track whether or not Windows Defender Security Center now uses the same anti-malware engine as System Center Endpoint Protection. But who cares as long as it does its job, right

Well, that’s the question we need to ask, and to try and answer it I’ve invited Raymond  share some thoughts on the subject. Raymond is an independent IT architect and trainer from the Netherlands.

Windows Defender in Windows 

Until not so long ago, Microsoft didn’t really show a lot of interest to get Windows Defender on the market as a competitive offer to technically compete with competing products from other vendors. The only valid reason for a company to choose Windows Defender  Windows and that it provides integration with its update mechanisms. Tests regarding system security products showed time and time again how the product was no better than mediocre in detection and prevention of malware infections. It always bugged me as a Windows expert that Microsoft didn’t seem to bother and use its knowledge of the platform to come up with the best protection possible and expand on the feature set in a way that only Microsoft can do on the platform.

This all seems to have changed over the past year. Finally, Microsoft showed some care about the malware detection tests and optimized Windows Defender AV to also detect the stuff that other vendors are detecting during those tests. At the same time, Defender seems to become a brand to protect Windows as Windows Defender Advanced Threat Protection (W DA T P) hit the market. W D ATP is the cloud-based intrusion detection platform that Microsoft offers as a part of the Windows E 5 offering. The platform uses machine learning algorithms to detect behavior caused by hacks and malware. Especially when a hack is not based on malware, this is a brilliant way to detect that things are going wrong.

Windows Defender 2018-2019

With the release of Windows 10 Fall Creators Update, or version 1709, Microsoft seems to really have gotten on target when it comes to making Windows Defender a serious contender for its competitors. The timing appears extremely well-staged at a moment because Kaspersky, one of the market leaders, is in a heavy storm of accusations that its software has been hacked and misused by state intelligence organizations, and more companies are looking at replacing Windows 7 for Windows 10.

Windows Defender 2018-2019

To me, it was quite a surprise to find that probably the biggest changes in Windows 10 is a suite of Host Intrusion Prevention features that are tightly related to Windows Defender. These new features come under the Windows Defender label and provide new capabilities to prevent havoc from happening on your systems. The Host Intrusion Prevention suite is named Windows Defender Exploit Guard and it consists of the following.

features: 

  • Windows Defender Exploit Protection
  • Windows Defender Attack Surface Reduction
  • Windows Defender Network Protection
  • Windows Defender Controlled Folder Access

One surprising fact is that most Exploit Guard features don’t come enabled by default. Even though that appears to contradict the “Secure by Default” slogan, the main reason appears to be compatibility. As we all remember what happened the last time when Microsoft tried to force a new security feature enabled by default when it introduced User Account Control with Windows Vista.

Another surprise is that the whole Windows Defender Exploit Guard suite is available in all versions of Windows 10. This looks as if Microsoft is now using a different approach introducing new security features in Windows 10, as all these features are available in all Windows 10 SK Us.

Windows Defender Exploit Protection

Windows Defender  can be referred to as the new E MET built-in Windows 10. EMET is a solution that enables you to configure a number of the built-in process mitigations on applications when the developer did not do so. This prevents many potential zero-day exploits from happening. The reality is that EMETs exploit protections have increased from five in EMET to 18 in Windows 10 RS3. People who have implemented EMET before know it is hard to test and find the exploit protections that work and do not break specific applications. Microsoft managed to find a way to relieve you from most of the burden when implementing WDEP. The answer is Windows Defender Advanced Threat Protection (WDATP). If your system is licensed and configured to use WDATP, WDATP will automatically configure the Microsoft-recommended process mitigations on the system, covering most publicly available applications and providing maximum protection against zero-day exploits. As it does not require Windows Defender AV, even those who opt for a different AV solution can make use of this feature.

Windows Defender Attack Surface Reduction

Now Windows Defender Attack Surface Reduction is a set of aimed at disarming some of the most-used malware tactics. The measures in Attack Surface reduction can, for instance, block the execution of obfuscated scripts or stop Office applications from creating child processes.

The list of Attack Surface Reduction measures consist of:

  • Block executable content from email client and web mail
  •  Office applications from creating child processes
  • Block Office applications from injecting into other processes
  • Impede JavaScript and VB Script to launch execut ables
  • Block Execution of potentially obfuscated scripts
  • Block Win 32 imports from Macro code in Office

And the beauty of all this is it works with a single requirement: Do not disable Windows Defender AV

Windows Defender Network Protection 

Now Windows Defender Network Protection is an example of simple effectiveness. The feature uses Smart Screen technology to block any executable from connecting to potentially malicious HTTP-based sources on the Internet. Once again Windows Defender AV is a requirement for enabling Windows Defender Network.

Windows Defender Controlled Folder Access

Controlled Folder Access is Microsoft’s answer to the ever-increasing number of ransomware infections. Controlled Folder Access allows only a list of known applications to write in user folders like Documents, Pictures, or alike.

My first experience with the feature showed that the default configuration is pretty strict.  The feature mode for a while  logs to create a white list that will not annoy the users away from this really nice feature. The single option  Controlled Folder Access is an easy way to create a white list from the event logs. You probably already guessed there is one requirement for using Controlled Folder Access. That is (of course) Windows Defender AV.

Compelling features

Windows Defender AV is becoming pretty slick with the latest improvements  AV products.

Introduction of Windows Defender Exploit Guard  even  a few compelling features that many organizations do not want to live without. You can find more information about Windows Defender Exploit Guard on the Windows Security Blog on Tech Net.
