Windows 10 Windows Defender vs Other Third-Party Security Tools - Equitable Comparison

Many people compare or read a comparison between Windows Defender with third-party's Internet Security, Total Security and so on. Most of these comparisons are not equitable because these tools have antivirus as well as other security tools such as Firewalls, Internet security and others, while Windows Defender is just an antivirus program.

What Windows built-in security services are included and enabled by default?

Windows Defender is an antivirus software that protects your system against viruses, malware, spywares and network threats. It is a Windows Service that works with other Microsoft security and maintenance services such as Windows Firewall and Microsoft SmartScreen (which is Internet security: phishing and malware filter used in several Microsoft products including Internet Explorer, Hotmail and Microsoft Edge). All of these services are enabled by default and starts at system startup, of course, if you do not have installed a third-party security software.

When you install a third party security tool, Windows turns off its corresponding security service. For instance, Windows turns off Windows Defender automatically when you install a third party antivirus and you cannot turn it back on because Windows Defender settings become inactive unless you uninstall the third party antivirus.

In addition, security updates and critical updates protect against vulnerabilities to malware and security exploits. By default these updates are downloaded and installed by Windows Update service automatically.

Moreover, Windows Update takes care of updating Windows Defender automatically. Updating Windows Defender does not require system restart.

Finally, take in your consideration that Microsoft security tools are built into the Windows operating system and fully compatible, reliable and working smoothly with fewest bugs and side effects.

How to schedule Windows Defender to run system scan?

By default, Windows Defender is scheduled to run quick scan as part of daily basis Windows Automatic Maintenance job when the system is in idle status. When the task is missed or interrupted by the user (when the user returned to use the computer), the system re-runs the scan the next time the system goes to idle status (re-runs the scan from beginning and does not resume it from the point it stopped last time).

To see what tasks are included in the system Automatic Maintenance, change the time or run the system maintenance manually in Windows 10, open "Security and Maintenance" window in Windows Control Panel (or type Security and Maintenance in the search box near to the Start menu). Then expand Maintenance section to see the Automatic Maintenance.

                Security and Maintenance -> Maintenance -> Automatic Maintenance

Windows Task Scheduler service is used to schedule a Windows Defender system scan. Do not change the default quick scan to full system scan. Microsoft, the system builder and developer, sets all necessary settings of security and maintenance tasks to give you the best over-all system security and performance for most consumers to perform their normal daily works.

Windows 8 (More detailed with screenshots - Same procedures for Windows 10):

http://www.thewindowsclub.com/schedule-scans-in-windows-defender

There is no need for, and I do not recommend, a daily full system scan. This (full scan) takes more computer resources for a long time and slows down your system performance. In my opinion, the best practice to perform a full system scan is when you feel that your system is infected by a virus or when you clicked on a suspicious link online or in an email message and the quick scan did not solve the problem. In these cases, run the full system scan manually. If you want, you can run the full system scan from time to time (once a month for instance) manually.

Although, you don’t need to schedule a full system scan, you can setup your own scheduled task to perform a full system scan and, again, don’t change the Microsoft default settings. For this purpose, use Windows Task Scheduler tool.

To run a Quick, Full or Custom scan manually, open Windows Defender then from the main page (Home) select a scan option and click "Scan now" button to start the scan.

Who needs to change built-in security tools?

Maybe, you need to change some of default settings, built-in tools and/or use additional security tools using higher-rated 3rd-party software, if you are working on public place and using many of others possibly infected external memories (such as Flash drives and External HDDs), connecting to an unsafe public Wi-Fi frequently, opening unknown and dangerous websites, playing with hackers or visiting their websites (maybe for downloading, installing or testing some illegal apps), visiting porn websites, and/or downloading and testing apps from unknown sources. In these cases, you are exposing to viruses and external attacks from hackers more than usual.

Although, for many of these cases, Windows built-in security tools with default settings are good enough to block these external attacks, you can use higher-rated 3rd-party tools and/or antiviruses depending on the case you have.

To increase your system security, if you want, you can install Malwarebytes Anti-Malware as a precaution.

Why we prefer third-party antiviruses?

There are some key points that most consumers prefer third-party antiviruses:

  1. Virus and Spyware Protection:

    Most of higher rated third-party antiviruses, as I saw, give you around 5% to 15% more virus detection capability than Windows Defender. If you want to play with hackers or visit unknown and dangerous websites, then you need higher rated antivirus and firewall to protect your computer. The thing that most of people do not.

  2. Virus Scan Speed

    Many of higher rated antiviruses scans for viruses faster than Windows Defender. However this is an advantage, but you will not do a full scan for viruses every day. There are situations that you need to scan a driver or full computer scan such as when you feel that your system not working properly and the quick scan did not solve the problem. Maybe, this happens once in several months and sometimes a quick-scan solves the problem, if your antivirus includes this option.

  3. Resource Usage

    Some antiviruses needs less system CPU and memory usage to protect your pc. Although, Windows Defender has good system resource usage, some third-party software give higher rating in some tests.

What are the advantages of Windows Defender and Windows security system?

If you want to choose between Windows built-in security and a third-party security software, take the following points into consideration that many people do not think about.

  1. Windows security tools including Windows Defender, Windows Firewall and Microsoft SmartScreen are fully integrated in Windows operating system and working in the background. You will not even feel that they exist in normal conditions.
  2. When you upgrade your Windows to a newer version or install an update of current version, Windows security services are updated as well. Many third-party antiviruses have some issues when you upgrade your Windows or, sometimes, when you apply some updates to current version, and some of them stop working completely.
  3. Quick-scan checks the places on your computer's hard disk that spyware is most likely to infect.
  4. Windows Defender has a feature called Real-Time Protection (RTP). RTP is running in the context of the logged-on user. It monitors the registry and file system on the computer by using agents that monitor auto-start extensibility points (ASEP). RTP continuously monitors your computer and scans everything you download or run on your PC.

Although, many other third-party systems have this feature (RTP) and/or quick-scan option, RTP in Windows Defender with the default scheduled quick-scan kills some advantages of other higher rated third-party antiviruses such as lower system resource usage, and higher scan speed. With the existence of RTP and scheduled quick-scan, you do not need full system scan and startup scan because the RTP and quick-scan do the job. Therefore, the higher rated “higher speed of full system scan” and “lower system resource usage” are no longer advantages of third-party antiviruses. This is because you do not need startup scan and full system scan anymore except in some situations, such as when you feel that you system is infected and quick scan did not solve the problem, you perform a custom or full system scan depending on the case you face.

Summary:

If you want to compare or read a comparison between Microsoft security system with other third-party security systems, such as Internet Security and Total Security tools, you have to consider Windows Defender along with Windows Firewall, Microsoft SmartScreen, Windows Update, and Windows Schedule Tasks all together to get accurate and reliable results.

Recommendations:

If you want to give a priority to higher security, then choose a higher-rated third-party security software. In the other hand, if you want to use your computer for your daily business and give the priority to higher over-all system performance and reliability with good security level, then the best choice for you is Windows built-ins security including Windows Defender, Windows Firewall and Microsoft SmartScreen.

If you are not on a public Wi-Fi, Windows Firewall does its job efficiently and you don't need to install a third party firewall. If you chose to use a third-party product and you are not on a public Wi-Fi and you do not need extra services included in the third-party security systems, it is enough to get an anti-virus rather than a complete security set. For example, use ESET NOD32 Antivirus instead of ESET SmartSecurity or Bitdefender Antivirus instead of Bitdefender Internet/Total Security. Moreover, these extra tools usually slow down the system.

In my personal opinion, I recommend to stay on Microsoft built-in security system for a while, and do not purchase any third-party product because, as I see, most of them (if not all) have issues on windows 10 and they are not fully stable on the newly released operating system. After a couple of weeks, maybe you will find more stable security systems in the market. Then you can decide whether you want to use one of them or stay on Windows built-in security system – the most stable security system.

If you decided to stay on Windows built-in systems, you can improve your system security by using some of additional free tools. When you feel your system is infected or attacked:

Many people compares Windows Defender with 3ed party's Internet Security, Total Security and so on. Most of these comparisons are not equitable because these tools have antivirus as well as other security tools such as Firewalls, Internet security and others, while Windows Defender is just Anti-Malware program.

Windows Defender is a Windows Service that works with other Microsoft security and maintenance services such as Windows Firewall and Microsoft SmartScreen (which is Internet security: phishing and malware filter used in several Microsoft products including Internet Explorer, Hotmail and Microsoft Edge). All of these services are enabled by default and starts at system startup, of course, if you do not have installed a 3ed party security software.
If you have installed a security tool, the Windows corresponding security tool stops working. For instance, if you have installed a 3ed party antivirus, Windows Defender stops working. If you have installed a 3ed party firewall, Windows disables Windows Firewall. Same thing is true for Microsoft SmartScreen.

Although, you do not need to setup a custom schedule scan for Windows Defender, you can serve Task Scheduler to schedule Windows Defender scan at any time you want.

See the following articles to setup a schedule task for Windows Defender.
Windows 8: http://www.thewindowsclub.com/schedule-scans-in-windows-defender
Windows 10: http://windows.microsoft.com/en-us/windows-10/schedule-a-scan-in-windows-defender

Moreover, Windows Update takes care of updating Windows Defender automatically. Updating Windows Defender does not require system restart.

Finally, take in your consideration that Microsoft security tools are built into the Windows operating system and fully compatible, reliable and working smoothly with least bugs and side effects.

Summary:
If someone wants to compare between Microsoft security system with other security systems, such as Internet Security and Total Security tools from other 3ed party companies, he/she has to include Windows Defender along with Windows Firewall, Microsoft SmartScreen, Windows Update, and Windows Schedule Tasks all together to get accurate and reliable results.

Windows Defender does not shut itself off if you have a third party software installed. I HAVE a third party software and have to go in every time I logon and turn Defender off. This is a terrible way to have this setup. Just because grandma can't protect her computer without help, does not mean the rest of us are incompetent. This should NOT be set to on by default, and certainly, if it is, I should have the option of turning it off permanently.

This article is about comparing Windows Defender with other 3ed party antiviruses. Kindly, open a new thread to ask this issue with Windows Defender.

There are many things may cause this issue including:

  1. You may have some problem in Windows 10 upgrade.

  2. You may using an antivirus version that does not fully support Windows 10.

    http://www.pcantivirusreviews.com/Comparison/

  3. You may use some antivirus that scans for viruses on fly (without installation and integration in Windows).

  4. The antivirus software may not include some feature that Windows Defender has. Therefore, Windows Defender continues to protect your pc.

After discovering recently that a top Antivirus Internet security company had been hacked I removed there software.

I checked the Windows firewall with GRC shields up can't recall if it went into true stealth mode immediately or after a couple of scans but it does the job

whereas the 3rd party software was unable to learn it kept failing don't know why.

I do run a malwarebytes app as a precaution, runs fine alongside windows security tools supplied.

I figure if someone wants to hack in to your computer doesn't matter what you do, if they know what their doing they'll get in anyway. All these large companies spending bucket loads of money throwing it at the problem still get done over by stupidity.

just my thoughts, 

In my opinion, it is good idea to use Malwarebytes Antimalware alongside with Windows Defender as additional support.

https://www.malwarebytes.com/

The premium edition includes RTP which is compatible with Windows Defender as well as several other antivirus software according to their website.

https://www.malwarebytes.com/pdf/reviews/AVTestingReport.pdf

Malwarebytes Anti-Malware (the free edition) does not include the RTP and you can use it to scan you system on demand when needed.

Another case when you have a malware attack and it is preventing your anti-virus software from run or it attacked the anti-virus itself. In this case, you use Windows Defender Offline (or any other 3rd-pary you trust) to scan you system using a bootable disc/flash.

MICROSOFT PURPOSELY PUTS WINDOWS DEFENDER "ON" AND SHUTS DOWN ANY THIRD PARTY VIRUS PROGRAMS. ALL YOU HAVE TO DO IS GO TO THE WINDOWS DEFENDER PROGRAM OR APP AS SOME NEW PEOPLE HAVE NAMED A PROGRAM NOW. SHUT IT OFF AND KNOW THIS: WINDOWS CLEARLY STATES THAT EVERY TIME IT IS SHUT OFF FOR AWHILE (NO TIME SPAN GIVEN) IT WILL TURN IT BACK ON AUTOMATICALLY. SO I ADDED THE APP TO MY TASKBAR AND EVERYTIME MICROSOFT "THINKS" IT IS GOING TO CONTROL ME, I'M FIGHTING BACK WITH "TURNING THEIR GARBAGE OFF".

THIS IS NOT RIGHT. WE AS CONSUMERS HAVE A RIGHT TO CHOOSE WHAT PROGRAMS OR YOUR STUPID NAME OF "APP" DECIDES WHAT PROTECTS ME AND MY COMPUTER AND MY INFORMATION! I'M NOT IN A SOCIALIST OR COMMUNIST COUNTRY SO I CONTROL MY CHOICES NOT SOME COMPANY OR GOVERNMENT. MICROSOFT IS BECOMING NOTHING BUT A CONTROL FREAK.

ONE DAY WHEN I HAVE ENOUGH MONEY I WILL SUPPORT APPLE AND NEVER AGAIN TOUCH ANOTHER WINDOWS PRODUCT FOR PERSONAL USE! NEVER!! I'M DONE WITH MICROSOFT'S ANTICS, CONTROL, INSTABILITY. THEIR FREE PRODUCT UPGRADE HAS DONE NOTHING BUT CAUSE ME ISSUES. I FIRST LOST ALL ABILITY TO USE MY DVD DRIVE, NOW I'M CONSTANTLY HAVING TO SHUT OFF THEIR WINDOWS DEFENDER ALL BECAUSE I WANT NORTON WITH A FAR BETTER PROVEN TRACK RECORD TO PROTECT MY STUFF. 

WHO THE HECK DOES MICROSOFT THINK THEY ARE? YOU HAVE NO RIGHT TO CONTROL FROM THE BACKGROUND HOW MY COMPUTER WORKS! TAKING AWAY A VALUABLE ASSET OF MY DVD PLAYER AND NOW NORTON - ALL I HAVE PURCHASED! TYVM! 

ONE DAY, ONE DAY I WILL NEVER USE MICROSOFT PRODUCTS AGAIN! AS GOD IS MY WITNESS I HAVE HAD IT WITH YOU PEOPLE. IF I COULD I'D THROUGH MY EXPENSIVE COMPUTER UNDER A TRAIN TRACK TO DEMOLISH THIS MICROSOFT PRODUCT, BURN THE REMAINS AND THROUGH THE SHARDS INTO A PIT IN THE GROUND AS A TIME CAPSULE WITH A NOTE ATTACHED IN PLASTIC FOR THE NEXT PERSON TO FIND. 

NEVER EVER SUPPORT OR BUY A MICROSOFT PRODUCT NOW OR IN THE FUTURE YEARS AND IF THEY CHANGE THEIR STINKING NAME, RUN FOR THE HILLS AND BURN EVERYTHING. THEIR PRODUCTS NOT ONLY CONTROL YOU, THEY SPY ON YOU! 

GOD I ABSOLUTELY HATE MICROSOFT NOW !!! ALL OF YOU WHO WORK FOR THEM SHOULD BE ASHAMED OF YOURSELVES. ONE DAY GOD WILL TAKE AWAY YOUR PROFITS BECAUSE OF WHAT YOU DO TO THE MASSES WITH ALL THE HEADACHES AND STRUGGLES WE HAVE ALWAYS FACED USING YOUR PRODUCTS. EVERY UPGRADE MAKES NEWS, NOT BECAUSE ITS GREAT BUT BECAUSE  OF THE PROBLEMS.

THERE'S SOMETHING TO BE SAID OF LIVING OFF THE GRID. OLD SCHOOL LIVING IS STILL ALWAYS GOING TO BE THE WAY TO STAY OUT OF THEIR CLUTCHES! EVEN OUR GOVERNMENT IS TRYING TO TAKE AWAY OUR RIGHTS, EACH DAY AND MICROSOFT HAS JOINED THEIR WAYS! 

It appears that you're pretty upset so I don't wish to throw fuel on the fire, but somehow I don't think that Microsoft would deliberately prevent 3rd party security software from working on there O/S the legal issues could be quite costly.

You didn't mention what version of Norton you are using so all I can offer is a link to Norton with the current compatability of their programs at this date they aren't current with all products.

Also there's a link on the site to upgrade if you so wish.

Rule number 1 is don't user Windows Defender unless you aren't going to pay for an antivirus software solution. Windows Defender is now classified as the base or benchmark for antivirus / anti malware, it stops less than 80% of viruses and malware that get in. Please think about using a paid solution or at the very least use a free version of a paid solution. 

Windows Defender Capture rate Source.

Of course you can use your own paid or free antivirus software but there is no rule says that don’t use some free antivirus unless you aren't going to pay for an antivirus software solution.

In my opinion and based on my knowledge, the followings are some rules you should consider to decide which antivirus and security tool you need.

Rule number 1: You have to have an antivirus (built-in, free or paid). Bad antivirus is better than no antivirus.      

Rule number 2: There is no 100% perfect solution.

Rule number 3: You are the first level antivirus if you know what you open and what you click.

Rule number 4: Any 3rd party solution may affect your system’s performance, stability, and/or Windows upgrading issues more than built-in services such as Windows Defender and Windows Firewall.

Rule number 5: Windows Firewall is enough and you don’t need a 3rd-party firewall If you are sitting behind a private local firewall (hardware) such as home and office private routers (most routers include a firewall).

Antivirus Tests:

There are some points to consider when testing an antivirus and other security tools such as firewalls. The following points are quoted from AV Test (www.av-test.org) website.

Protection

Protection against malware infections (such as viruses, worms or Trojan horses).

  • Protection against 0-day malware attacks, inclusive of web and e-mail threats.

  • Detection of widespread and prevalent malware

System Performance.

Average influence of the product on computer speed in daily usage.

  • visiting websites, downloading software, installing and running programs and copying data.

Usability.

Impact of the security software on the usability of the whole computer.

  • False warnings or blockages when visiting websites

  • False detections of legitimate software as malware during a system scan

  • False warnings concerning certain actions carried out whilst installing and using legitimate software

  • False blockages of certain actions carried out whilst installing and using legitimate software

AV-TEST: Test antivirus software for Windows 10 - October 2015  (www.av-test.org)

The following page shows AV Test test results for Windows 10 Windows Defender 4.8 for September and October 2015.

https://www.av-test.org/en/antivirus/home-windows/windows-10/october-2015/microsoft-windows-defender-4.8-153747/

The following page shows the best antivirus software for Windows 10 according to AV Test.

https://www.av-test.org/en/antivirus/home-windows/

From this page you can see that Windows Defender is even better than some famous antiviruses in protection perspectives and better than others in system performance. And it is one of the best antiviruses and gained highest score in usability perspectives. Note that some of these tools that comes after Windows Defender in some criteria are paid tools.

AV-Comparatives - Independent Tests of Anti-Virus Software - Real World Protection Test Overview (www.av-comparatives.org)

This is another organization offering systematic testing security software products.

http://chart.av-comparatives.org/chart1.php

This organization, also, gave Microsoft a good score for Real-World Protection Test: 94.5% for December 2015 which is, again, better than some other well-known anti-viruses. Note that many higher rated antiviruses have bad score in False Alarm Test (Usability – mentioned above). Also, check the performance diagram.

If you install a third party virus protection it will turn off defender.
I have used Windows Defender and Firewall only, and found that I ended up with many adware programs and so many PUPs that my computer wouldn't run proper.  The programs that come and change your home page, search engine.  That may not seem a nuisance to some, but a real pain when you don't know what happened, not to mention the time needed to remove these blasted things from the computer.  Don't tell me Defender is enough, you're crazy if you think so.
