Avast vs Windows Defender- Which Antivirus is Better

There will always get a need for antivirus software as long as computers have existed and will exist, whether or not they get linked to the Internet, and selecting between Avast vs Windows Defender is the first decision you will make. Viruses are often frightening to people, and Antivirus Software is a data security application installed in a computer system to guard against harmful viruses. However, if you don’t have much spare budget, you don’t always want to squander it on frivolous purchases. Most operating systems come with built-in antivirus protection; the question is whether you need third-party antivirus software.

Read the rest of the article. Today, I’ll tell you all you need to know about whether or not you should use third-party security software and the differences between Avast and Windows Defender. You will be able to make your own decision after the article.

Avast vs Windows Defender: Summary

What an Antivirus Can Do to Help Your Computer – Do You Need a Paid One like Avast?

Antivirus protection isn’t simply for blocking computer viruses by just looking at the name because it’s not just viruses you should be concerned about. Malware is a generic phrase that applies to numerous forms of threats. It is arguably more widespread nowadays, using a different strategy to achieve an illegal purpose. Whatever it is, one thing is sure: the dangers that still exist are severe.

Windows, macOS, iOS, and Android have all included malware protection in some form or another. On the other hand, Hackers are always coming up with new and inventive ways to rob individuals of their money, sensitive information, or data. Antivirus software is like a bright light beam in a world complete with dark illnesses. They have several benefits to offer. But, other than the one that comes with your operating system, do you require a separate one?

However, your operating system’s software still gets regarded as nothing more than a starting point. So, third-party antivirus software is probably still required, but some gadgets need it more than others. Yes, many fight against antivirus software, and this is especially true in the case of iOS devices, which never required third-party security in the first place.

Also, the extra expense of having an antivirus might be why individuals don’t advocate it over the built-in security. But, Endpoint protection and responsiveness and automated investigation and restoration get not included in the built-in security. As a result, choosing between Avast vs Windows Defender should be simple, and you should be using both, but I’ll go into more depth as you read the post.

Avast vs Windows Defender – Which One You Should be Using

To compare Avast vs Windows Defender, consider all of the factors that contribute to the success of any product. It will assist you in comprehending how these programs function independently and in conjunction with one another.

Avast vs Windows Defender – Company Overview

Avast antivirus dashboard

Avast is a Czech multinational cybersecurity software firm started by Pavel Baudi and Eduard Kuera in 1988 as a cooperative. Avast has been motivated by fierce independence, a commitment to safeguarding people’s right to privacy and security, and a solid technical talent pool throughout its 30-year existence. They now employ over 1,700 individuals in 18 different locations throughout the world. With a purpose to guarantee that everyone can govern what they share online and with whom they share it. Avast develops and promotes commercial and consumer IT security software for servers, Desktop computers, and mobile devices.

Avast’s experience in machine learning and artificial intelligence allows them to cope with existing malware efficiently. At the same time, their extensive threat data provides them with the size, speed, and accuracy to instantly find, classify, and guard against any new threat. On the other hand, Avast is well-equipped to flourish in this new and rapidly expanding market.

Microsoft Firm is an American global technology corporation founded in 1975 by Bill Gates and Paul Allen. The company provides computer software, electronic goods, computers, and associated services, and its name is well-known. It is the second-largest firm globally and one of the most expensive brands in the IT sector. Because of its market value of more than $2 trillion, everyone can readily conclude that Microsoft is the world leader in the industry of personal computer software.

Microsoft Windows’ history stretches back to 1981, when Microsoft began developing Interface Manager software. It has changed since then, with Windows 11 being the most recent release from the business. Microsoft has released several products throughout the years. Its products get now used by over 1 billion people across the world.

Winner: Avast is nowhere approaching Microsoft regarding client acquisition and corporate worth. Both companies have a particular focus. Microsoft is a full-fledged tech business that provides the operating system and the tools that go with it, whereas Avast is primarily concerned about security. Now, If you merely look at the firm’s history, no company comes close to Microsoft in terms of its ability to retain clients over time. At the same time, Avast did experience some issues as a result of controversion, which I will discuss later in this article.

Avast vs Windows Defender – Antivirus Overview

Avast is one of the most well-known brands in the market. Avast availability on various platforms has allowed it to grow in popularity quickly. The organization has been working around the clock to deliver the most up-to-date features to the market. Upgrades to their antivirus and anti-malware solutions are among them. It’s synonymous with internet safety, stopping 1.5 billion+ cyberattacks worldwide, with over 435 million monthly active users in 2022.

Avast Antiviral combines an antivirus engine that performs well in tests with an unexpectedly large number of extra functions. Avast One protects against various online dangers and prevents and eradicates viruses and other types of malware. It also provides VPN access, data leak prevention, and top-rated security and antivirus capabilities. As a result, having Avast One protects you from the whole range of viruses and malware and many of the most prevalent cyber-attacks. More significantly, Avast is excellent at preventing viruses from entering your computer, so there is no question of them affecting your computer.

Windows Defender has been around for quite a while, but it now got turned into a Windows app. Microsoft bought GIANT Anti-Spyware in 2004 and began transforming it into a Microsoft product. After multiple test cycles, the final product, Windows Defender, was released in 2006 as an anti-spyware solution for Windows XP and Windows Server 2003. Microsoft Security Essentials got introduced shortly after Windows 7 was released. It is because the Window Defender wasn’t enough to defend the operating system from all forms of harmful malware hiding on the Internet at the time. However, following Windows 8, Microsoft updated the application to include the same malware prevention technology as Microsoft Security Essentials.

Windows Defender gets described as a complete antivirus solution in its most recent edition. It claims to protect you from harmful websites in real-time and integrates with your browser. Your Outlook inbox is also scanned for malicious attachments by Windows Defender.

Winner: Although Microsoft is one of the world’s top IT companies, malware defense is not their primary concern. Although, at a basic level, Microsoft Windows Defender guards against well-known viruses and malware types. It lacks several features that are currently commonplace in many third-party antivirus solutions. In most circumstances, though, Windows Defender can keep you completely safe. For the most part, Window Defender serves as a backup to a proper antivirus program. The Avast One offers a considerably more extensive threat-detection network and a variety of built-in privacy safeguards, making it the apparent winner in this scenario. However, we’ll go through the more characteristics that set the competitors apart and make them the most feasible security solution.

Avast vs Windows Defender – Pricing

Avast Antivirus gets touted as an award-winning free antivirus that provides superior protection to keep you safe online. Yes, most of the features are still free. Several free antivirus programs are available, but not all of them will give complete security. Avast Free Antivirus is entirely free and provides all the protection you require. PCMag, AV-Test, and other independent experts frequently laud and honor Avast Free Antivirus. Avast provides premium subscriptions, commercial pricing, and a free version for individual users. When it comes to specific plans,

Windows Defender is different from other free antivirus programs in that it does not require installation. Also, It comes preinstalled with a bundle of features that make it a complete solution if you don’t want an antivirus. Previously it was not that efficient. Today, however, Windows Defender has progressed to the point that it can now provide malware protection comparable to any free or commercial antivirus product. The Windows operating system includes all of its components.

Winner: Even though Windows Defender is absolutely free, it isn’t adequate to compete with leading third-party PC antivirus software. Yes, it will keep your computer generally secure from most malware. Its anti-phishing security gets restricted to Microsoft Edge; for protection on other browsers, you’ll need Avast Free Antivirus. Although the free edition of Avast is not as protective as the paid version, free Antivirus is never available for complete protection. It’s best to use both simultaneously because using Microsoft Defender Antivirus alongside another antivirus solution will benefit you.

Avast vs Windows Defender – Features

To get a better understanding of what Avast vs Windows Defender brings on the plate, let’s discuss their features on the comparatively same ground.

Avast Features :

Avast’s free plan includes all of the fundamental security tools to protect you from online and offline dangers. If you choose one of Avast’s premium security suites, you’ll get solid protection, additional features, and multi-device coverage.

  • Virus Scan Settings: Avast’s Smart Scans function combines a security check with scans for additional issues like browser trackers and temporary files. Rather than only searching for viruses, the central concept is to clean up your PC and keep it working smoothly. Aside from that, four more scan features are more targeted and assist you in creating tailored scans.


  • Malware Protection: The new Avast One Essential includes Avast’s sophisticated Malware-fighting technology. Avast blocks all access to the malware’s hosting URL or wipes all the malware payload before it finishes downloading. Avast takes action when malware attempts to operate on a computer. In that case, it will promptly detect the most known malware samples, quarantine them, and remove them. Even if a new type of danger emerges, Avast’s network of over 400 million users will automatically transmit anti-malware updates to you.


  • Phishing Protection: Avast One is capable of much more than just protecting you from viruses and other infections. AV-Comparatives’ 2021 Anti-Phishing Certification Test gave Avast Antivirus the highest score. As a result, Avast One identifies phishing attempts and prevents them from reaching you. Furthermore, it is automatically updated whenever a new assault is detected, ensuring that you get protected in real-time against the Internet’s ever-changing danger environment.



Additional Prominent Features:


Window Defender Features:

Windows Defender is already installed on your computer if you have Windows 8.1 or 10. Many people will not realize the defender is active until they receive a message from Windows Defender. The new Microsoft Windows Defender Security Center defends against malware, ransomware, and other spyware. Still, it also maintains your entire security and is available for free on all Windows operating systems.


  • Malware Protection: If you don’t have any other malware protection or your antivirus premium features have expired. Windows Defender takes over and tries to keep you secure. The defender has consistently placed among AV-top Test’s ten solutions for malware, and it has a flawless score for malware eradication


  • Phishing Protection: Windows Defender Browser Protection gets meant to help defend you against phishing attempts and other online risks. The phishing protection interfaces only with Microsoft’s browsers: Microsoft Edge and Internet Explorer. The Windows Defender Browser Protection plugin may get downloaded from the Chrome Web Store if you wish to add defender’s protection to Chrome.


  • Ransom Protection: Unauthorized programs can’t access essential document folders with Windows Defender, and you can quickly add more. As a result, the defender provides some ransomware protection. But it’s more of a rudimentary defense against actual ransomware threats. It’s merely a Microsoft product that got integrated while allowing the users to transfer important personal folders to OneDrive so that they can still access them if they get locked by a ransom attack


Winner: Avast One Premium gives clear advanced level security and capabilities, but Window Defender is the best alternative to go with if you’re on a budget.

Avast vs Windows Defender – Interface

Because Avast’s primary focus is on antivirus software, its developers haven’t rested. They’ve continued to update the program to incorporate new security features for user satisfaction and device protection. And updates are sent as soon as there is a need for them.

When it comes to the user interface for Windows Defender, engineers take their time to create interfaces with easy navigation methods and user-friendly features. Even though Windows Defender was once a little outdated, it has substantially improved in light of recent upgrades. However, interface updates might take years, as they are frequently associated with significant OS changes, such as the move from Windows 10 to Windows 11.

Winner: Even for users with minimal computer experience, Windows Defender Security Center may get accessed with fairly primary navigation, but if you find it challenging, it will remain the same throughout the OS until you move to a newer OS. While Avast is constantly enhancing its design across all platforms, it is pretty simple to use, even if several extra options are available to users.

Avast vs Windows Defender – Performance

It has excellent detection rates and adequate malware protection, according to Avast. Yet, it does not hinder system performance or irritate users by being resource hungry. Avast uses a small number of resources overall and does not affect the system’s performance or slowness. In the Performance Test, Avast obtained an Advanced Plus three-star rating. In contrast, the Window defender received a lesser rating. You will also have Avast other tools if you believe your PC requires a performance boost. Like, with Avast Cleanup Premium, you can speed up your PC and delete unneeded files. With Avast Ultimate, you can protect and optimize your PC simultaneously.

Because Windows Defender is a built-in feature of Windows 8 and Windows 10, it does not influence system speed. As a result, it should function as smoothly as the rest of the system. It doesn’t slow down a computer in general, and its background scanning is almost invisible in most circumstances.

Compared to many other antivirus solutions, it is relatively low. However, although Windows Defender’s mandatory protection makes computing safer, the defender always operates in the background. So at the time, it had greater permission to utilize resources than other Antivirus. There are mixed views and testing results on Window Defender performance from independent testers. Windows Defender came in the worst position (most significant performance impact) in the October 2020 Performance Test. However, it came in top place in the most recent Performance Test (lowest impact). 

Winner: Antivirus impacts performance, regardless of how little emphasis firms place on it. A system minimum requirement gets usually considered while installing third-party software like Avast. However, in the case of Windows Defender, you will already have it, and installing additional software on a low-end PC is not recommended.

Avast vs Windows Defender – Customer Support

Avast provides a basic, comprehensive customer service that includes a considerable part of helpful FAQs and a detailed resource section. It has articles published on the everyday difficulties users may encounter. This material should be beneficial to both beginner and expert users. For more critical issues, the company has a 24-hour phone center. Apart from general assistance, it provides a premium paid support plan for $39.99 per year. It includes 24/7 phone, email, live chat, and remote access support. It promises to help you remotely repair any computer and software difficulties through its technical support personnel. The premium support plan is currently available in one language only: English.

Because Windows Defender is a preinstalled component, Microsoft will fix any issues you may have with Windows. However, Windows Defender does not have its support service; instead, the support service covers all Microsoft products. The Microsoft community is one of the world’s largest. And Windows users may get a lot of help from the FAQ Center, which has tips on setting up scans and fixing common problems. Other choices, such as Microsoft Virtual Agent, will be available. Aside from that, customers have access to Microsoft’s global network of support, which includes phone help and a ticketing system.

Winner: You can come across problems at any moment, and both firms will provide essential help, but in the case of Window Defender, you don’t get dedicated support as you do with Avast. As a result, Avast takes the lead in Antivirus support.

Does Avast vs Windows Defender Provide a Virus Protection Promise?

Neither company offers a Virus Protection Guarantee. In their Terms and Conditions, Microsoft expressly says that they will not be responsible for your computer’s security when it becomes infected with the virus. So, instead, look for Antivirus with a Virus Protection Promise, such as McAfee or Norton. It entails a virus eradication service given by a professional, and it may get included in your subscription plans.

According to AV Tests, between Avast vs Windows Defender, Which Provides better Offline and Online Malware Protection?

Windows Defender recognized just slightly more than half, 54.8%, of all malware samples when offline in the most recent AV-Comparatives malware test. In contrast, Avast caught 93.4 % of offline samples. While  In the online detection test, Avast also edged out Windows Defender, with a rate of 96.3 % to Microsoft’s 95.9% with four false alarms, while Avast only had one false warning.

Can You Have Both Avast and Window Defender?

The simple answer is Yes! But if you seldom use the Internet and rely solely on Microsoft’s products, such as the Edge browser. In that case, Windows Defender is adequate. Still, a third-party antivirus application gets required for complete surfing and internet security. As a result, any third-party antivirus that you trust gets recommended. However, keep in mind that if Windows Defender detects a third-party antivirus application, it will switch itself off and remain a backup alternative. Having two security programs on your computer may exhaust your device resources.

Antivirus Past Controversies?

Apart from the viewpoints of features and price, you may also want to check the antivirus company’s controversies.

  • Avast has got accused of sharing personal user data and profiting from it, albeit the closure of subsidiary Jumpshot has curtailed this practice. Many people are still skeptical, but there is no reason to believe it is a threat because it has halted now
  • A Vulnerability in Windows Defender Laid Undetected for 12 Year Consequently, attackers may utilize Windows Defender indefinitely for such an attack because it comes preinstalled with Windows and is present on hundreds of millions of devices and servers worldwide. The issue gets resolved after upgrading to the current firmware.

Bottom Line

In general, Windows Defender and Avast are fierce rivals. Windows Defender provides comprehensive malware protection free for life, whereas Avast outperforms Windows Defender in system speed. Subscribe to a commercial version of Avast’s antivirus software. You’ll get a more extensive range of enhanced functions that Windows Defender doesn’t have.

There’s nothing wrong with using Windows Defender as an antivirus and internet protection package for certain primary PC users. However, if your PC contains many personal and sensitive data, I’d recommend switching to Avast One instead of Windows Defender.
