Windows Defender Vs. Antivirus Software

Windows Defender Antivirus

Windows Defender is finally better than a last option, though it’s still not quite as good as most totally free antivirus software application.

  • Integrated into Windows 8.1 and 10
  • Malware protection getting better
  • Now part of Service Center
  • Still missed many threats
  • Full scan slows down PC
  • Not many extra features

Concealed below the surface area of every Windows 8.1 and Windows 10 system, Microsoft’s Windows Defender is built-in antivirus defense for those who do not want to think of malware, scanners or threats. The program lacks a few of the things we consider given in security software, however it has the advantage of being well-integrated into the os.

Nevertheless, while the malware-protection abilities of Windows Defender and its Windows 7 sibling, Microsoft Security Essentials, have actually improved vastly in the previous couple of years, they still drag the protection you’ll get with the majority of totally free antivirus software. For truly much better security, we recommend Avast Free Antivirus or Bitdefender Antivirus Free Edition.

Costs and What’s Covered

Windows Defender is constructed into Windows 8.1 and Windows 10. There’s no other way to completely disable the software application without modifying the Windows Registry, and it constantly runs unless you set up a third-party antivirus product. There are no choices for upgrades or premium products that supply more features.

With the most recent main construct of Windows 10, the Creators Update (variation 1703), Microsoft has actually relabelled Windows Defender as Windows Defender Antivirus, just to make clear what it does. However since it’s still called Windows Defender on older versions of Windows 10, and on all versions of Windows 8.1, we’ll use the names interchangeably.

If you’re searching for a full-featured application that can help keep your secrets, look elsewhere. Windows Defender supplies just standard security and takes pride in it.

The recent version of Windows 10 also introduces the new Windows Defender Security Center. That’s a new merged interface for numerous Windows security and privacy tools that were formerly accessed independently, consisting of the firewall, system-performance screens, adult controls and Windows Defender itself.

On Windows 7, Windows Defender’s functions are managed by Microsoft Security Essentials (MSE), which needs to be downloaded from the Microsoft website and manually installed. It uses the exact same malware-detection engine as Windows Defender. (To make things even more complicated, Windows 7 includes an entirely various program called Windows Defender, however that’s deactivated if you set up MSE.)

Antivirus Protection

Windows Defender is one of the most commonly used AV products in the world, and many individuals who depend on the program do not even understand it’s there. It will instantly upgrade itself if you’ve enabled Windows 10 or Windows 8.1 to always have the most recent system updates.

To secure your PC from infection, Windows Defender uses conventional signature-matching scanning to compare potential malware against a database of known dangers. It also uses heuristic analysis, which keeps track of software application behavior and other qualities, to catch new “zero-day” malware or malware that rapidly changes its code to evade signature detection.

Anything that looks odd gets uploaded to Microsoft’s laboratories for additional analysis. New signature updates are sent to users numerous times per day. (You can choose to not participate in the malware-collection program with an alternative in Windows Defender’s Settings section.)

Windows Defender’s malware protection is not terrific compared to the similarity Bitdefender or Avast, but its capability to spot and scrub rogue code has improved in the past few years.

Like the majority of anti-viruses software application, Windows Defender continuously runs in the background, however you can put the real-time scanner into snooze mode to reduce interruptions. Microsoft’s cloud-based Block at First Sight technology rapidly react to dangers such as a ransomware attacks.

You can scan an individual file, folder or drive with Windows Defender by browsing to that item through Windows Explorer, then right-clicking it. Windows Defender also automatically scans new USB drives as they are linked to the system.

Antivirus Performance

Windows Defender’s malware protection is not as good as the similarity Bitdefender or Avast, however its capability to spot and scrub rogue code has improved in the past couple of years. It’s now an efficient (though occasionally flawed) tool for protecting your system.

In recent two-month examinations conducted by German independent lab AV-TEST on Windows 10, Windows Defender stopped 99.0 percent of formerly hidden “zero-day” malware in both May and June of 2017.

There’s still some work to do on that front, especially when compared to rivals that got best 100-percent ratings in both months, such as Avast, AVG and Bitdefender. (In antivirus software application, what counts is how much malware survives.) But thinking about that Windows Defender stopped just 80.5 percent of zero-day malware in September 2015 and 88.1 percent a year later, we can’t help however be impressed by the progress.

As far as discovering extensive, known malware on Windows 10 went, Defender stopped 99.8 percent in May and 99.7 percent in June. Avira and Bitdefender scored perfectly in both months. Windows Defender misidentified a tremendous 16 safe items as malware (incorrect positives), nevertheless, versus approximately three.

On Windows 7, AV-TEST assessed Microsoft Security Essentials (MSE), which shares its malware scanner with Windows Defender. In both January and February 2017, MSE scored a best 100 percent against zero-day malware, a big advance for the program. (Avast and Bitdefender scored 100 percent as well.)

Still, MSE missed 0.7 percent of prevalent malware in January and 0.4 percent the following month, arguably the worst scores of the six brands of free AV software we just recently evaluated. MSE registered three false positives in February.

Over five rounds of assessments from February to June 2017 performed by Austrian laboratory AV-Comparatives, MSE running on Windows 7 stopped approximately 98.8 percent of malware originating from harmful websites. It also registered 27 incorrect positives over those five months.

By contrast, Bitdefender had a 99.9 percent detection rate, with five incorrect positives over 5 months. Panda had a 99.8 percent rate and 11 false positives.

Security and Privacy

If you’re looking for a full-featured application that can assist keep your secrets, look elsewhere. Windows Defender supplies just basic defense and takes pride in it.

You get Microsoft’s SmartScreen filter to obstruct potentially dangerous sites, but it works just with the Internet Explorer and Edge web browsers. Email accessories can be obstructed based on their contents, however only in Microsoft Outlook and Microsoft Office 365, and just as the emails are opened. Third-party e-mail clients do not get any security.

Like Google Chrome and Mozilla Firefox, Microsoft’s Edge web browser offers to save passwords, but Windows Defender lacks anything like Avast’s password manager. There’s no file-level file encryption, but if you have the Windows 10 Pro, Enterprise or Education editions, you can use Microsoft’s BitLocker disk-encryption system.

Windows Defender lacks a file shredder and a hardened web browser for electronic banking and shopping. There’s no local-network scanner to find susceptible devices.

The software application does not have a system-rescue disk, too, however you can use the Windows recovery tool to roll back the system to a previous time.

Efficiency and System Impact

Because Windows Defender is part of Windows, there was no way for us to evaluate its post-installation system impact, however we did time system scans and measure their impact. On an Asus X555LA laptop running Windows 10 with 6GB of RAM, an Intel Core i3 CPU and 36GB of files on a 500GB hard disk drive, we ran our OpenOffice standard test, which matches 20,000 names to 20,000 addresses on a spreadsheet. It ended up in 6 minutes and 58 seconds.

Windows Defender is a reasonably slow scanner. It took 48 minutes and 45 seconds to go through our system’s disk drive; it looked at 350,396 files along the method and found absolutely nothing amiss. That’s more than 3 minutes much faster than Bitdefender’s initial complete scan, however Bitdefender’s complete scans get much faster if you duplicate them; Windows Defender’s don’t.

Windows Defender was able to do a fast scan of the most vulnerable areas in 2 minutes and 36 seconds. That’s about as long as Avast Free Antivirus’ fast scan took.

The scans had a combined effect on system efficiency. Windows Defender’s quick scan had only a 2-percent effect, with an OpenOffice conclusion time of 7:07, simply 9 seconds slower than the standard.

On the other hand, the Full Scan gobbled up system resources and taped an OpenOffice rating of 10:59. That’s a downturn of a massive 58 percent, making Windows Defender easily the worst of the totally free malware programs in this regard.


Even as part of the new Security Center, Windows Defender’s user interface is still minimalist and austere, with a fundamental white, blue and green color pattern. The bright side is that Windows Defender lets you resize the interface window and use it complete screen, an uncommon capability among antivirus software application.

At any time, you can begin a Full, Quick or Custom scan, and inspect if the real-time security is switched on and the meanings depend on date.

The Security Center supplies an overlay a level above Defender, with icons for five main categories. Virus & Threat Protection (i.e., Windows Defender) provides access to a Quick Scan and Advanced Scans for Full, Custom and Offline scans.

Device Performance & Health makes certain you have current drivers and Windows software application in addition to sufficient storage and battery life; the Fresh Start lets you factory-reset the operating system.

Firewall Program & Network Protection shows that the firewall program is active and offers a way to whitelist apps. App & Browser Control lets you choose whether the system will obstruct or caution about online risks. Lastly, the Family Options let you establish Windows 10’s adult controls, limitation PC use and track what your kids are doing online.

Each product gets a green check mark when the threat level is minimal, but that can rapidly alter to red if anything fails. The main Defender window and the Security Center have Task Tray icons that are so comparable that you’ll scratch your head trying to decide which is which.

Overall, this plan is less efficient if all you wish to do is run a Full Scan, which is now an extra click away. A Custom scan lets you select folders or drives to examine. There’s no way to schedule a malware scan from within Defender, however you can use the Windows Task Scheduler to make Defender do it.

While SC supplies a new look to Defender, it in some cases obstructs. In the lower left corner of each Security Center window is a Settings link, which just toggles the malware and firewall program notifications. To get to the nitty-gritty information, you still need to go into the old Defender’s Settings section, which paradoxically remains in the upper right of its windows.

Installation and Support

Unlike with other totally free malware items, there’s absolutely nothing to install with Defender. It’s currently part and parcel of a Windows 8.1 or 10 system. Windows 7 uses Microsoft Security Essentials, which need to be downloaded individually.

Security Center has no Help category, so it’s back to the old Windows Defender user interface for support. There, you’ll discover a direct connect to the company’s assistance presence online and a method to submit a malware sample. There are lots of ideas and guidelines, however all support is done through the online forum.

Bottom Line

Being developed into Windows has its advantages. Windows Defender Antivirus is constantly running below the surface, and its new Security Center includes a veneer of modern-day style. But its sluggish malware scanner has a heavy system impact, and while Defender’s defense is enhancing, it still lags behind the majority of other products in defense.
