Windows Defender or Avira, which antivirus software is a better option in 2019?
Read this data-driven Windows Defender versus Avira comparison to make a wise decision.
In today’s era, antivirus software isn’t an option anymore; it’s become a necessity.
As we put more and more information online and use the internet for buying all sorts of things, we also make ourselves vulnerable to a wide variety of threats that are only becoming more sophisticated and complex with time. This means that digital security also needs to evolve and become more effective.
AV-test.org, an unbiased testing organization with a reputation for excellence, discovered almost 900 million new malware samples last year. This breaks down into about 350,000 new malware samples per day. The numbers are mind-boggling, and they’re only likely to grow as time goes on.
It’s clear that you need reliable antivirus protection for all your internet-capable devices. But just any security software won’t do the trick. Relying on free or low-end security products that offer limited security is not a good idea — especially when your security and privacy are on the line. Instead, you should invest in a full-blown premium security suite for complete digital security and peace of mind.

Now, let’s delve into the details.
In additional excellent anti-malware security, most modern antivirus companies offer a full suite of advanced security-related features and utilities as part of their security suites.
First, let’s see what’s included in Windows Defender.
Windows Defender (also called Windows Defender Security Centre) comes pre-installed with all PCs that run on Windows platform. You can’t uninstall it or remove it, but it automatically turns off when you install a third-party product.
The software comes with a scanner that checks for all sorts of malware threats, including ransomware, and a firewall that keeps an eye on your network traffic and acts as a shield against malicious traffic. Like most security software, the product receives new malware definitions from Microsoft’s cloud malware database to protect against new and emerging threats.
The useful “Find my Device” module lets you locate your PC if it gets lost or stolen. You can also remotely lock or erase your computer if you feel that your personal information is in danger of being stolen.
Also included with Windows Defender is a full suite of parental controls. These features let you do things such as monitor the web activity of your children, prevent them from visiting certain websites or downloading certain games or apps that may be age-appropriate, and limiting the amount of time they can spend on their device each day.
Other than the features mentioned above, there’s much included in Windows Defender.
Now, let’s see what features Avira has in comparison.
Avira has a free version called Avira Free Antivirus for Windows. The freeware, like Windows Defender, is pretty barebones in terms of advanced features and utilities, but it does offer protection against different types of malware threats. The software is regularly updated with new malware definitions via the Avira Cloud, providing immediate protection against emerging threats.
Next up is Avira Antivirus Pro — the first paid tier of coverage from this company. Besides top-drawer malware protection, this suite offers some extra perks that are not part of the free software. These include the HomeGuard tool (identifies and fixes vulnerabilities in your home network) and the Privacy Pal utility (helps shred confidential files and applies strict privacy settings).
Another level up is Avira Internet Security – the company’s more advanced antivirus package. This suite offers everything included with the Pro package, plus a full-blown password manager that can store all your sensitive details in a secure vault. There’s also a software update tool in the package; this will automatically update all the applications and drivers installed on your computer as well as fixing security flaws. In addition, it optimizes your computer hardware performance.
Finally, there’s Avira Prime – the company’s full-blown antivirus offering. This premium software package has everything that comes with the previous suites, plus some additional utilities. The additions include a premium VPN tool that you can use for anonymous web surfing and a comprehensive clean-up tool that cleans junk files and improves the performance of your computer.
The Prime suite also gives you access to Avira’s apps for Android and iOS to extend security to mobile devices. You’ll also be able to use all the new products that the company will release in the future at no additional cost.

Winner: Avira. Overall, Avira’s products come with a more comprehensive feature-set than Windows Defender.
2. Malware Protection
The ability to protect your computer from all sorts of malware threats is the primary purpose of an antivirus program. To determine whether Windows Defender or Avira can protect you better, let’s turn to some independent testing organizations who can provide us with unbiased test results and give us a clear answer to this question.
AV-Test is a well-known independent antivirus software testing company that regularly evaluates all popular security software in terms of three different categories: Protection, Performance, and Usability. Their most recent evaluations were held in April 2019.
Both Avira and Windows Defender got a perfect 6/6 rating in the Protection category of AV-Test evaluations, meaning both software possess solid malware defense. (See this and this for detailed results.)
AV-Comparatives is another independent Austrian organization that tests and ranks different antivirus software. In their recent real-world protection study, Avira got the highest possible award issued by the company, the ADVANCED+ award, because of its excellent malware detection rate with a low number of false detections.
Windows Defender didn’t perform as well as Avira in this test and could only get the second-best ADVANCED award.
Winner: Avira. Overall, both companies tied in one independent evaluation, while Avira got the better of Windows Defender in the other evaluation.
3. System Performance
Good antivirus software shouldn’t strain your system resources, no matter what kind of computer you have. If a software significantly slows down your system, it’s basically a virus itself.
To find out which software is better in terms of system performance, we’ll again refer to the recent independent evaluations.
In AV-Test’s recent April 2019 evaluations, both Avira and Windows Defender scored 5.5 out of 6 in the Performance category, which is a good score but not perfect.
The experts at AV-Comparatives also conduct a similar test to measure the impact different antivirus software put on systems while running in the background. Avira got the second-best ADVANCED award in their April 2019 test, while Windows Defender’s results were surprisingly poor; it put the most impact on test systems and came last in the test.
Winner: Avira. Overall, Avira wins this round of comparison because of better overall scores in independent evaluations.
While all the aspects we considered above are important, we can’t disregard how intuitive and easy-to-use the user interface of each antivirus software is in its day-to-day use.
First, let’s examine Windows Defender’s interface.
To open Windows Defender’s interface, you’ll have to go through several different clicks to get to the Security Center, which is the dashboard for the Defender software.
Overall, the interface is open-framed and uses a modern, minimalist visual aesthetic. On the left-hand side, you can find the seven different major categories for operations. Each category has a self-explanatory name, so you should be able to access everything that Defender has to offer even if you don’t have a lot of experience with computers.
The biggest downside to the interface is the lack of the capability to schedule scans. This means that you’ll have to initialize every single scan that the software performs.
Let’s take a look at Avira’s interface.
Avira’s interface uses a green and gray dashboard. There’s also a big checkmark at the top of the screen that will be there if everything is running as expected. This will change to a red exclamation point if there’s an issue that needs your immediate attention. All of the primary operations, such as the real-time protection, firewall, and web and mail protection functions, have switches that you can flip to turn them on or off as you wish.
On the main page, you can also find records of your scans, plus logs of anything that the software has found. You can also schedule different types of scans and access various reports compiled by the software with a few clicks.
While Avira will automatically update itself several times a day, you can also update it immediately whenever you feel an update is necessary. In addition, you can easily locate a link that can let you install the Avira app on your Android phone or tablet.
Winner: Avira. Avira’s user interface is more intuitive and straightforward than Windows Defender’s.
Windows Defender is totally free and comes pre-installed with PCs, while Avira offers a free antivirus solution as well as several excellent premium suites.
Let’s take a look at Avira’s paid security suites.
Avira Antivirus Pro costs $44.99 per year for one license that you can use to protect either a PC or a Mac. Avira Internet Security protects one device for $57.99 per year. Avira Prime, the premium bundled package offered by the company, protects up to 5 devices for $99.99 per year.
