In this digital era, hackers are evolving faster than technology and this is what concerns us and so should you be about the safety of your personal information. You will need to be skeptic so that when someone or typically an app asks you to provide information, you could effortlessly say “No” to it.

However, to focus on the topic on hand we’ll walk you through a step-by-step comparison based on the different features and services offered by each antivirus software.

The first very aspect that we’re considering here is “Features” of each product:

Here we go!

Which Antivirus Software offer Advanced Features – Avira or Windows Defender?

When cyberpunks are advanced, it’s easy to be left. That’s bad because that’s how you put your sensitive information at risk. According to the latest statistics, every 39 seconds, a hacker attack takes place and attackers are only getting increasingly sophisticated.

Windows Defender


You’ve have heard the name of “Windows Defender” certainly because it is a freeware for Windows Users – i.e. you get it for free on Windows-based systems (be it your PC). If you’re running Windows 10 on your machine and you don’t get your hands to “Windows Defender”, it is because it has been turned off and will be needed to be turned on to work.

There’s no method to uninstall it, however, it gets automatically turned off when third-party antivirus software is pre installed on the machine. With its firewall you get decent security protections from malware threats.

It gets automatically updated and is decent for basic device protection. It does have constant updates to improve real time protection that can help you deal with the suspicious files on the local disks. Or if you want the Windows Defender antivirus to update during a certain time, you can set your active hours. Overall, it’s just okay. It’s certainly better than nothing but doesn’t hold a candle to other, more premium antivirus choices.

There’s nothing you need to install Windows Defender on your system – it comes as built-in software that eradicates the fear of unwanted subscriptions and nagware.

What will make your day is the “Family Protection”! We know that you wouldn’t believe, neither did we when we first came to know that it also has got different options for the “Parental Control”. To assure that everything is as okay as it should be, you can take a look at the family’s devices if they are also using Windows operating system.

What if your Windows 10 device is lost or stolen? Have you done something about it in advance? If not, it is time to make the most use of “Find my device” feature accessible for the Windows 10 users. You can find your device and then ring, lock, or erase the personal data stored on the device to avoid getting in the wrong hands. This service is also available on mobile devices.

However, who really uses Window 10 mobile phones?

Who’s the Winner in Avira vs Windows Defender?

We hope you’ve got the understanding of both Avira and BitDefender and if you still have no idea who the winner is, you should know that it is “Avira because it features more security-related features that allow it easily surpasses WD as a good Windows Defender alternative.

Avira vs Windows Defender: Malware Protection

Which software do you think is capable of offering better protection from all types of malware? Is it Avira or Windows Defender? It’s no wonder lack of malware protection can put your system at risk, which means your system is vulnerable and that’s when a hacker finds the leak into the system and gets unauthorized access to it with a wrong intention.

It, therefore, it is critical to understand which software offers improved advanced malware protection. To determine this, we’ve used the results from AV-Test (an independent IT security lab) that will help you get a clearer picture of the final evaluation. These security tests were run taking both of the antivirus software into consideration. Let’s see what we have got:

Avira’s Malware Protection:

Windows Defender vs Avira: System Performance

Which software has minimal impact on system performance? Is the winner Windows Defender or Avira? Always remember, a better-fit software won’t even slow down the performance of your system while it is running in the background.

What if a software slows your device down? Well, it’s definitely less than ideal as you want to be able to use your devices while it’s running. Otherwise, whatever you are doing – work, watching Netflix, or playing games will become a little annoying.

So, we strongly suggest that you choose an antivirus software that has the capability of running the system and programs smoothly (i.e. without any sort of interruptions whatsoever). Let’s figure out what the score of each product says about the system performance.

Avira’s Malware Performance:

WD’s Malware Performance:

Winner: Avira

Windows Defender vs Avira: Manageability

Is the program user-friendly i.e. does it offer as good accessibility as it should? That’s one of the questions you should be asking yourself if you’re on the lookout for an intuitive user interface. Since you should be utilizing the software on a daily basis, it should offer an easy-to-understand approach to the user.

Each software offers a different UI but you’ve to choose the one that offers suitability right in accordance with your needs. A good design lets you use more of the software since you will be able to use features with just a couple of clicks. On the other hand with a poorly designed software you will have to perform a large number of clicks that will waste your valuable time and can be frustrating.

An important aspect of design is color. The UI of the software must be soothing to eyes or you will end up straining your eyes while looking at the screen (or the software).

Let’s take a look at the User Interface (UI) to differentiate between both software:

Avira vs Windows Defender: Which is Less Expensive?

Do you want to purchase an antivirus software license that will break the bank? We know that you have a habit of burning holes in your pocket, but that doesn’t mean you should be paying extra when you can get the services at an affordable price.

Since the Windows Defender is completely free and doesn’t charge anything, it’d be easy for us to reach the final outcome.

Avira is also free and its free package is still slightly better than Windows Defender. Avira’s premium packages may cost some money, however, it won’t be a problem if you are fascinated about the affordability.

As each suite of Avira is priced differently and the cost of the software might also change as new features are added to the products, our experts’ recommendation is that you should keep yourself updated with the “Latest” pricing table that we’ve laid out below:

Avira’s Pricing Model:

Avast Antivirus SuitesLatest Price
Avira Antivirus ProLatest Price
Avira Internet SecurityLatest Price
Avira Optimization SuiteLatest Price
Avira Total Security SuiteLatest Price
Avira Business ProductsLatest Range

Winner: It’s not possible to mark the difference between both software as Windows Defender comes free and Avira is a Premium software.

Avira vs Windows Defender: Which Antivirus provides more Usability?

What about Usability? Does the antivirus software that you’re interested in lives up to your expectations? You can make sure of it through two ways – either you can use the software (that will require you to purchase the software) or you can experience the outcome by taking a look at what’s already been tested. The former process may not guarantee full satisfaction, however, speaking of the latter, it will definitely give you the satisfaction you crave for as you will get to hear the stories of many people who have used the software before.

But you don’t need to do anything as we’ve furnished the AV-Test scores that make it crystal clear which software offers better usability. When we took a look at WD’s usability, we saw two false detections (1st in March and 2nd in April) and we already know that lower values indicate better results and higher values don’t. We couldn’t find anything bad in the overall result of Avira’s usability.

But don’t just take our word for it – you can have a glimpse at the subsequent score:

Winner: Avira

Which Antivirus Software Has Better Customer Support

As Windows Defender is part of Microsoft, you get the benefit of its customer support system and the assistance you need to resolve any issues with this factory pre installed software. Microsoft does, however, wash its hands of any responsibility in the case that your Windows PC becomes infected by malware.

AVG, on the other hand, offers 24/7 live chat and phone support to its paying customers. It’s unclear what kind of customer service is available to users of the free version of their software so we call this one a tie since neither provider seems to have a perfect customer support system.

If you’d like to see the results, you can easily do that for both Windows Defender and Avira yourself. We’ve added the links because the different tests and run on a regular basis and no one really knows when there could be a modification in the score.

Final Thoughts for Avira vs Windows Defender

Both Avira and Windows Defender offer great features to meet the basic requirements. Nevertheless, a freemium software can’t be compared with premium software and we know that. Since WD is a free antivirus, it definitely doesn’t t feature all of those characteristics that you will get in a paid software – that’s why you pay for it.

Our recommendation: McAfee

From phishing scams to malware attacks, security threats grow increasingly by the day. Although the products we mentioned are very good, it cannot beat the likes of McAfee. With McAfee it has protection on all sorts of devices ranging from phones to even cars! It’s extensive product line-up has protected over 18.9 billion devices to this day. We are sure that you will come across a package that is perfect for you, to check out their line-up, click here!

Windows Defender is good enough for excellent malware protection against the typical malware samples you’ll encounter online.

But in the long term, you’ll want more advanced windows defender alternatives that can stand up to the full range of threats on the internet than the Microsoft Defender antivirus.
