6 Best (REALLY FREE) Antivirus Software for Windows [2022]

6 Best (REALLY FREE) Antivirus Software for Windows [2022]

Short on time? Here’s the best free Windows antivirus for 2022:

I tested every free antivirus I could find against thousands of old and new Windows malware files. Running virtual environments for various PC operating systems from Windows 7 – Windows 10, I not only looked at each antivirus’s malware protection capabilities, but also its user interface and its reputation for safeguarding user privacy. This wasn’t an easy task, and I learned that there are only a few free antiviruses out there that offer decent protection for Windows computers.

But there are also some really good free antivirus programs that offer improvements over Windows’s built-in protections. I was ultimately able to find 6 free downloads that each offer free virus protection alongside a decent set of free internet security tools.

That said, every free antivirus is going to include a few frustrating limitations. That’s why I always recommend investing a little bit every month into premium antivirus software that includes protection against all types of malware — with extra features like a VPN, password manager, parental controls, and dark web monitoring (Norton 360 has all of these features, is ranked as the best antivirus software for 2022, and is very affordable).

I tested and ranked each free antivirus listed here for malware detection, ease of use, and additional cybersecurity features. Unfortunately, no free antivirus includes all of the features you need for complete protection, but it’s better to protect yourself with the best free antivirus than no antivirus at all!

Quick summary of the best free Windows antiviruses for 2022:

UPDATE (2022): One of the top antivirus providers, Norton, recently removed its free package, but I’ve kept it on this list as a paid alternative because it really is one of the best internet security providers out there. If you don’t want to deal with the hassles of a free antivirus, a low-cost premium antivirus like Norton 360 is always a good choice. (Read the full Norton 360 review here.)

🥇1. Avira Free Security for Windows — Best Free Antivirus in 2022

🥇1. <a href="" title="Avira" rel="sponsored noopener noreferrer" target="_blank" data-btn-name="Affiliate Link - 349981" data-btn-indexed="1">Avira Free Security for Windows</a> — Best Free Antivirus in 2022

Avira Free Security for Windows is my favorite free Windows antivirus in 2022 — it has one of the best anti-malware engines on the market, includes more free features than any other competitor, and is really easy to use.

Avira’s virus scanner operates in the cloud — so its detection and analysis don’t actually take place on your PC — making Avira extremely fast, lightweight, and low on system resources. During my testing, Avira’s anti-malware engine detected all of the malware files I previously downloaded to my computer, and I was able to run CPU-intensive programs during scans with almost zero slowdown.

Avira’s free antivirus also comes with some excellent extra features, such as:

  • Safe Shopping browser extension.
  • Privacy & performance optimizer.
  • VPN (500 MB monthly limit).
  • Password manager.
  • Game booster.
  • Firewall.
  • File shredder.
  • And more…

The Safe Shopping browser extension for Firefox and Chrome is really good — it blocks suspicious phishing sites, web trackers, and unwanted advertisements. The extension also automatically recommends links to better deals when shopping online. I was actually able to find a lot of good deals, but it didn’t work 100% of the time (still pretty good though!).

I’m also a big fan of Avira’s privacy and performance optimization tools — they cleaned out my cookies and junk files, and also fixed hidden privacy settings that were leaking personal information on the web.

That said, I think the VPN that comes with Avira’s free antivirus is not that good. It’s limited to just 500 MB per month, which is barely enough to watch a couple of really short videos, and it only lets you connect to 1 server location.

If you want a fast and reliable VPN with unlimited data, multi-device support, and advanced system optimization tools, you should consider upgrading to Avira Prime, which costs $59.99 / year — it’s a bit pricier than some competitors, but it’s one of the best antivirus suites of 2022.

Bottom Line:

Avira’s cloud-based, free virus scanning engine is one of the best on the market — it’s lightweight, fast, has perfect detection rates, and is 100% free. I’m also a big fan of Avira’s Safe Shopping browser extension and privacy optimizer, both of which offer significant improvement over Microsoft’s built-in protections. To get more advanced internet security protection, you’ll need to upgrade to one of Avira’s paid plans, which start at $45.99 / year — but in terms of free Windows antiviruses, it doesn’t get better than Avira.

🥈2. Panda Free Antivirus for Windows — Good Virus Protection with Decent Extras

🥈2. <a href="" title="Panda" rel="sponsored noopener noreferrer" target="_blank" data-btn-name="Affiliate Link - 349985" data-btn-indexed="1">Panda Free Antivirus for Windows</a> — Good Virus Protection with Decent Extras

Panda Free Antivirus for Windows is lightweight, secure, and easy to use — during my tests, Panda’s antivirus scanner detected significantly more adware, spyware, and ransomware files than Windows Defender. Panda’s real-time protection also performed really well, blocking most of the malware files I tried downloading to my PC.

I also like that Panda has a gaming mode in its free antivirus — whenever you’re playing a game or watching a video in full screen, Panda automatically suspends notifications.

Another thing that makes Panda a good choice for Windows users is the Rescue Kit feature, which allows you to download a bootable version of Panda to a USB drive and then use the USB drive to clean an infected PC and get it up and running again.

Panda’s free antivirus also comes with a secure VPN. It provides fast connection speeds, but it only lets you connect to 1 server and has a data limit of 150 MB per day — this is a big improvement over Avira’s 500 MB per month, but it’s still not nearly enough data for streaming or file sharing. If you’re interested in unlimited streaming or torrenting, you’ll need a better VPN (check out our list of the best antiviruses with VPNs here).

You can only get unlimited VPN data (and access to select various worldwide servers) on the Panda Dome Premium plan, which also offers extra features like a firewall, anti-ransomware protection, anti-phishing protection, advanced system tune-up tools, a password manager, and parental controls, for $66.99 / year. All of Panda’s premium plans come with a 30-day money-back guarantee.

Bottom Line:

Panda’s free antivirus is a good, easy-to-use antivirus, offering 100% free real-time malware protection. With lightweight malware scanning, an automatic gaming mode, a Rescue Kit, and a VPN, Panda is an excellent free internet security product. However, the VPN is limited to 150 MB per day on a single server. If you want unlimited VPN access — and other extras like a firewall, anti-phishing, password manager, and parental controls — you’ll need to upgrade. Panda offers 4 different pricing tiers for paid users, which start at $28.49 / year, so it’s easy to find the right plan for you — or you can just give Panda Free a try and upgrade later.

🥉3. TotalAV Free Antivirus — Most Intuitive Free Antivirus

🥉3. <a href="" title="TotalAV" rel="sponsored noopener noreferrer" target="_blank" data-btn-name="Affiliate Link - 838153" data-btn-indexed="1">TotalAV Free Antivirus</a> — Most Intuitive Free Antivirus

TotalAV Free Antivirus provides excellent virus and phishing protection — during my tests, TotalAV’s cloud-based malware scanner detected and removed more malware samples than most antivirus programs, successfully identifying even very tricky ransomware and cryptojacking files.

TotalAV’s phishing protection is also very good. It uses a huge blacklist to identify known phishing sites as well as an AI-powered phishing detection system to detect new threats. In my testing, the anti-phishing tool scored a near-perfect detection rate, stopping me from entering more malicious sites than Chrome’s native phishing tool.

TotalAV is also the most intuitive free Windows antivirus on this list, with easy-to-use and easy-to-understand features and functions inside a minimalistic, well-designed dashboard. I had no problems navigating TotalAV’s dashboard, and I found it very simple to access and use all of the provided tools.

That said, unlike Avira, TotalAV’s free plan for Windows doesn’t come with a lot of protections. The biggest drawback of TotalAV Free Antivirus is that it doesn’t have real-time protection, meaning you won’t get notified in case a malicious file attempts to make changes to your PC in real time.

Upgrading to one of TotalAV’s premium plans brings you real-time malware protection as well as useful extras like device optimization tools, a VPN with unlimited data, a password manager, and more. TotalAV’s paid plans start at $19.00 / year, and they’re all backed by a risk-free money-back guarantee for 30 days.

Bottom Line:

TotalAV’s free Windows antivirus is excellent at removing malware and blocking phishing sites. It’s also one of the most intuitive antivirus programs on the market, which makes it an ideal choice for beginners. However, TotalAV Free doesn’t come with real-time protection and it doesn’t include any extra features. To get real-time scanning, PC optimization tools, and a VPN with no limitations, you’ll need to upgrade to one of TotalAV’s low-cost premium plans, which start at $19.00 / year.

4. Kaspersky Security Cloud (Free) — Good Range of Free Features

4. <a href="" title="Kaspersky" rel="sponsored noopener noreferrer" target="_blank" data-btn-name="Affiliate Link - 27528" data-btn-indexed="1">Kaspersky Security Cloud (Free)</a> — Good Range of Free Features

Kaspersky Security Cloud — Free is good at detecting and removing malware, and it also comes with plenty of extras — including:

  • VPN (200 MB daily limit).
  • Password manager (15 entries limit).
  • Data breach monitoring (only 1 account).
  • Basic system cleanup tools.
  • File shredder.
  • Virtual keyboard.

Kaspersky’s free antivirus provides good real-time malware protection, but its additional features are very limited.

Kaspersky’s VPN provides access to 1 server location and 200 MB per day — more daily data than Panda or Avira — but still not enough for streaming or other data-heavy tasks.

And Kaspersky’s free password manager only saves a total of 15 entries — this includes both logins and sensitive documents (like credit cards or passport details). I can’t say I’m too impressed with Kaspersky’s data breach monitoring either — free users can only check the email associated with their Kaspersky account (and they have to do it manually, unlike paid customers who get automatic data breach checks).

If you like Kaspersky’s interface and you want access to its unlimited VPN, password manager, parental controls, and web protections, then you’ll have to upgrade to one of Kaspersky’s paid plans, which start at $29.99 / year. All Kaspersky purchases include a 30-day money-back guarantee.

Bottom Line:

Kaspersky’s free antivirus comes with a good malware scanner and a ton of additional features, but most of them are very limited in functionality. Kaspersky’s VPN has a daily cap of 200 MB, the password manager lets you store up to 15 logins and credit cards, and the data breach monitoring only checks 1 email address. Upgrading to one of Kaspersky’s paid plans gets you all of these features without any limitations, plus extras like parental controls, advanced web protections, and more.

5. Malwarebytes Free — Minimalistic Virus Scanner

5. <a href="" title="Malwarebytes" rel="sponsored noopener" target="_blank" data-btn-name="Affiliate Link - 838159" data-btn-indexed="1">Malwarebytes Free</a> — Minimalistic Virus Scanner

Malwarebytes Free is a good choice for users looking for a simple antivirus scanner that they can install and forget about. Malwarebytes’s virus scanner uses a virus database as well as heuristics to catch all types of malware — and it performed pretty well in my tests, detecting around 90% of the malware files I hid on my PC. However, it did miss a few well-hidden files that competitors like Avira and TotalAV detected.

Apart from the scanner, Malwarebytes Free also comes with a browser extension that protects against a wide range of threats, including malware, ads and trackers, scams, and PUPs. One of the things I like the most about this extension is that all of the protections are turned on by default, so there’s nothing for you to do (but you can easily turn off one or all of the protections).

In my tests, Malwarebytes’s browser extension blocked the majority of risky sites I attempted to visit, scoring a 90% phishing detection rate. However, the extension wasn’t as accurate at blocking ads — I visited dozens of sites filled with ads, and Malwarebytes blocked only around a third of the ads.

Malwarebytes’s free plan is a simple virus scanner with a good phishing tool, but it unfortunately doesn’t have real-time malware protection. To get real-time scanning, you’ll need to upgrade to Malwarebytes Premium, which provides coverage for up to 5 devices and starts at $39.99 / year. Malwarebytes Premium + Privacy also adds a good VPN for $99.99 / year. Both of Malwarebytes’s premium plans are covered by a generous 60-day money-back guarantee.

Bottom Line:

Malwarebytes Free is a minimalistic antivirus scanner with good virus detection and removal rates. It also comes with a browser extension that blocks malware, phishing sites, ads, and trackers. Upgrading to Malwarebytes Premium brings you real-time protection and coverage for up to 5 devices, whereas Malwarebytes Premium + Privacy also adds a VPN.

6. Sophos Home Free — Easy Remote Management

6. <a href="" title="Sophos" rel="sponsored noopener noreferrer" target="_blank" data-btn-name="Affiliate Link - 349989" data-btn-indexed="1">Sophos Home Free</a> — Easy Remote Management

Sophos Home Free offers pretty good free anti-malware protection. It also includes some helpful web protections and covers up to 3 PCs (all within its free antivirus package).

In my antivirus testing, Sophos was able to detect a decent amount of virus and malware threats, but it missed all of my test ransomware files — that’s because Sophos’s free version doesn’t include ransomware protection, which I think is a pretty big problem. And while Sophos also offers basic anti-phishing protections (they’re better than Chrome’s built-in protections) they’re not nearly as as good as Avira’s free anti-phishing tools.

One thing I really like about Sophos is its remote management feature — you can log into Sophos’s online dashboard and access antivirus scanning and real-time protection updates on up to 3 devices.

In addition to multi-device protection and remote management, Sophos is also a decent choice for families because it has free parental controls. However, Sophos’s parental controls are pretty basic — you can only choose which categories of sites to block. If you’re looking for advanced parental controls like app scheduling and location tracking, you should consider a premium antivirus like Norton 360 Deluxe.

Sophos Home Free is pretty good, and Sophos Home Premium adds advanced malware and ransomware scanning, additional web protections, and coverage for up to 10 devices, for $44.99 / year — and it has a 30-day money-back guarantee.

Bottom Line:

Sophos offers pretty good antivirus scanning and remote management for up to 3 devices — which is pretty generous for a free antivirus. Sophos’s free version also has basic parental controls (only content filtering) and anti-phishing protection. Users looking for coverage on up to 10 devices, advanced malware and ransomware protection, and advanced web safety tools should upgrade to Sophos Home Premium.

Bonus. Norton — Best Overall Windows Antivirus in 2022

Bonus. <a href="" title="Norton" rel="sponsored noopener" target="_blank" data-btn-name="Affiliate Link - 1561165" data-btn-indexed="1">Norton</a> — Best Overall Windows Antivirus in 2022

Norton is by far the best Windows antivirus in 2022 — and while it doesn’t currently have a free plan, it offers a risk-free 60-day money-back guarantee, which gives you 2 months to try it out and see if it’s right for you.

In addition to providing perfect malware detection against all known and emerging cyber threats, Norton also has excellent phishing protection, a smart firewall with tons of customization options, and online banking and shopping protection.

It also comes with a wide range of quality extras, including:

  • VPN (unlimited data) — maintains fast speeds, works with streaming sites like Netflix, and has extras like Tor support and split-tunneling.
  • Password manager — generates, saves, and auto-fills logins, audits password security, and has an automatic password changer (only top standalone brands like Dashlane offer this functionality).
  • Parental controls — filters inappropriate content, limits device usage, and monitors YouTube and Hulu usage (Norton ranks #1 on our list of the best antiviruses with parental controls).
  • System optimization tools — removes unwanted files from Windows and web browsers, improves boot time, and defragments hard drive.
  • Dark web monitoring — scans dark web forums, data breach databases, and credit reports in real-time.
  • And much more…

Norton is also very easy to use across all operating systems, offers coverage for up to 5 devices, and doesn’t cause any system slowdown — it even has a gaming mode, so you can uninterruptedly play games while it runs in the background.

There are several plans to choose from, but Norton 360 Deluxe offers the best value — plus, with our special 61% discount, you can get it for only $39.99 / year. US users can also check out Norton’s LifeLock plans that start at $99.48 / year and add identity theft protection with up to $1M in insurance payouts and legal assistance. All of Norton’s plans are covered by a 60-day money-back guarantee.

Bottom Line:

Norton offers unparalleled malware protection, a wide range of high-end security features, and affordable plans for up to 5 devices. It also has a ton of extras, including a fast VPN, a secure password manager, and the best parental controls around. While it doesn’t have a free Windows plan, it provides the best value on the market, and it comes with a 60-day money-back guarantee, so you can try it out risk-free for 2 whole months.

Yes, You Already Have a Free Antivirus on Your PC, But It Isn’t Good Enough

Your Windows computer already comes with Windows Defender (some newer Windows 10 computers call it “Windows Security” or “Microsoft Defender”) — which, as we saw in our full review, is a decent free antivirus. But the problem with Windows Defender is that it’s rarely updated, it doesn’t include additional internet security protections, and it frequently has vulnerabilities that don’t get fixed (sometimes for several years!). Plus, Windows Defender consistently ranks below the top antivirus scanners in our independent lab testing. That’s why I always recommend keeping your PC as safe as possible with third-party antivirus software.

All of the free antiviruses listed here are significantly better than Microsoft’s Windows Defender antivirus. The free downloads on this list are from top-notch cybersecurity companies that are offering their premium antivirus protection for free. These are some of the top antivirus and anti-malware engines in the world — and our independent lab tests have confirmed that these antivirus engines are much stronger, faster, and better than Microsoft’s Windows Defender.

And some of the free programs on my list also include additional cybersecurity protections. My #1 free Windows antivirus, Avira Free Security for Windows, is particularly generous with its free offerings, but even Avira’s free plan has some annoying limitations that don’t exist on its paid plans.

In general, cybersecurity companies try to entice you with their free products, but they’re ultimately looking to convert you into a paying customer. If you’re looking for the best protection for all of your devices, you’ll need to pay for premium antivirus software. Unfortunately, there’s no way around this.

However, if you’re just looking for a simple free malware scanner with a couple of decent web protections that can improve on Microsoft’s Defender, then all of the products on this list will be good enough for you.

Free Antivirus vs. Paid Antivirus

Free antiviruses like Avira and TotalAV are pretty good, but their paid versions are way better — to begin with, they come with all of the internet security protections you need to stay as safe as possible online. And I’m not just talking about anti-malware protection here.

Premium antivirus software for Windows also includes extras like a VPN (to ensure you’re anonymous online), a password manager (to protect your sensitive data, including financial information), and parental controls (to make sure your child is protected on the internet). Together with a malware scanner, these tools are crucial to building a good online defense against hackers, scammers, and predators.

What’s more, paid antiviruses also include better customer support, so you know you can get help removing malware, accessing a feature, or solving any other issue with your antivirus at all times. Free antiviruses, on the other hand, don’t include live chat and phone support, so the only way to get assistance is to read a knowledge base, post a question on a forum, or send a ticket.

You can read more about paid antiviruses for different operating systems here.

Top Brands That Didn’t Make the Cut:

I’ve spent a long time compiling and revising this list to guarantee that I’m offering you a high-quality resource. You may be surprised to see that some of the top antivirus brands didn’t make the top 5. Here are a few of them:

  • Avast. While Avast — and their subsidiary antivirus company AVG — continue to offer two pieces of widely used free antivirus software (Avast Free Antivirus and AVG AntiVirus Free) their repeated privacy violations have caused too many concerns. You can read more here.
  • McAfee. McAfee is one of my favorite antiviruses of 2022. It comes with an advanced anti-malware engine, excellent web protections, and a VPN with unlimited data. But unfortunately, McAfee doesn’t have a free plan. However, if you need a high-quality antivirus, McAfee’s low-cost internet security packages are some of the best on the market.
  • Bitdefender. Unfortunately, Bitdefender recently discontinued its free plan for Windows, but it offers one of the most comprehensive internet security suites on the market, with perfect malware detection rates, high-end security features, and extras like a password manager, a VPN, and parental controls.

How to Choose the Best Free Windows Antivirus for Your Needs

  • Malware detection. The main purpose of an antivirus is to protect you against malware, so you want to make sure the program you’re running on your device has a good malware scanner that is able to identify both known and new malware, including trojans, spyware, ransomware, rootkits, and keyloggers. All of my top choices have perfect or near-perfect malware detection rates.
  • Minimal slowdown. An antivirus may slow down your system, making it hard to stream content, play games, or even browse the web, especially during a full system scan. But programs like Avira and TotalAV are pretty lightweight, so you won’t even notice they’re there.
  • Features. While most free antiviruses are pretty limited in terms of features, some free programs include a couple of extras. For example, Avira has a basic free password manager, Panda has a free VPN (150 MB/day), and Kaspersky has data breach monitoring.
  • Ease of use. Windows Defender is already pretty easy to use (it’s always running), so a free antivirus has to be very easy to use and offer the same excellent user experience that Microsoft has built into its native PC antivirus. All of the products on this list have user-friendly dashboards, intuitive features, and decent customer support.
  • Genuinely free. Many cybersecurity brands try to trick you into purchasing a premium product by offering a free trial and then making you pay to keep using the product. I’ve personally checked to make sure that all of the brands listed here offer free protection. I also included Norton on the list as a bonus in case you’re interested in learning more about the best paid alternative (plus, it comes with a 60-day money-back guarantee, so you can try it out for free).

Comparison of the Best Free Antiviruses for Windows in 2022

Antivirus Paid Version (Starting Price) Real-Time Protection Web protection Extra Features
1.🥇 Avira $45.99 / year Yes Yes Basic system tune-up, VPN, and password manager
2.🥈 Panda $28.49 / year Yes No Rescue kit and basic VPN
3.🥉 TotalAV $19.00 / year No Yes /
4. Kaspersky $29.99 / year Yes No Basic system cleanup, VPN, password manager, and data breach monitoring
5. Malwarebytes $39.99 / year No Yes /
6. Sophos $44.99 / year Yes Yes Remote management & protection for 3 PCs
Bonus. Norton $39.99 / year Yes (paid version) Yes (paid version) VPN, password manager, parental controls, dark web monitoring (paid version)

What’s the catch with free antiviruses?

There is no such thing as a truly free antivirus. You‘re always going to “pay” with something. Most antivirus companies limit the free version of their software to only offer basic protection. This leaves a lot of holes in your computer’s cybersecurity defense. The antivirus company hopes you’ll recognize you’re not well-protected, and they’ll try to get you to upgrade to the paid plan by sending you a ton of notifications and advertisements.

Some other antivirus companies even sell free users’ data to large corporations for marketing purposes — the popular free antivirus Avast (who also owns AVG) was just accused of doing this exact thing.

If you’re only using your device for simple online browsing or word processing, you’re probably fine with a free antivirus (and the ones on this list are the best free antiviruses out there). But, in general, if you store any kind of sensitive information on your Windows device, it’s always better to invest in a full-featured internet security suite than it is to trust a free antivirus.

Why should I use another free antivirus instead of Windows Defender?

Windows Defender is not a bad antivirus — it even ranks a little bit better than some third-party free antiviruses. But it just can’t compete when top cybersecurity companies like Avira and Panda are handing out excellent free antivirus software, almost all of which offer free protection against threats Windows Defender doesn’t protect against (like phishing sites, malicious web trackers, data breaches, etc.).

Indeed, most of the products on this list have substantially better free antivirus protection than Microsoft’s built-in Windows Defender antivirus.

You can read this blog post if you’d like to learn more about why Windows Defender isn’t good enough to keep users safe in 2022.

Is it safe to use a free antivirus?

If you choose an antivirus program from a trustworthy company, then yes. All of the brands on this list here are perfectly safe to use — the only difference between their free and paid versions is that the paid software includes additional features, like a VPN, a password manager, and parental controls, as well as better customer support options.

What’s the best free antivirus?

Avira is my #1 pick for the best free antivirus in 2022. It has one of the best antivirus scanners on the market, it’s very easy to use, and it has a great range of additional features (web protection, performance optimization tools, a password manager, a game booster, and a VPN).

While Avira Free is a really good antivirus, it does have some limitations — you can only use it on one device, it doesn’t provide ransomware protection, and the bundled VPN is limited to only 500 MB per month (barely enough to watch a few videos).

If you want full virus protection, a VPN with no limitations, and coverage for up to 5 Windows, Mac, Android, and iOS devices, I recommend you take a look at Avira Prime.

Is Avast free?

Yes, Avast does have a free antivirus, but I don’t recommend you use it, as Avast has been accused of collecting and selling user data for profit — you can read more about what happened here.

If you need a free antivirus, take a look at our list of the best free antiviruses in 2022 or just download Avira Free. But please keep in mind that all free antiviruses have some limitations — for example, Avira’s excellent free antivirus doesn’t have ransomware protection, and you can only use it on one device.

If you want the best protection for all of your devices, you need to pay for a premium antivirus program like Norton or Bitdefender.

What are the most common types of viruses that affect Windows computers?

While there are literally billions of malware attacks reported annually, trojans and adware are consistently the most common types of malware found on Windows computers.

Trojans look like other files with extensions like .exe and .doc — but once downloaded, trojans can initiate a backdoor attack to steal user data, to incorporate a Windows device into a botnet, to give a hacker direct access to a computer, or to simply crash and erase the entire OS.

Because hackers are constantly developing new malware for Windows, it’s crucial that your antivirus uses a malware database that’s consistently updated. Avira’s malware scanner is based in Avira’s cloud, so its malware database is always up-to-date, with no need for users to worry about downloading or installing database updates.

Will Windows allow me to install a free antivirus?

Absolutely! Windows will automatically turn off Microsoft’s built-in virus protection when a new third-party antivirus software is installed. If you decide to uninstall your third-party antivirus, your PC will automatically ask you to reactivate the Windows Defender antivirus.

That said, if you’re going to replace Defender, you should consider investing a little bit into premium cybersecurity protection. Free antivirus software just isn’t as good as paid antivirus softwares — you really do get what you pay for, and when it comes to keeping all of your devices and digital data safe, a paid antivirus like Norton 360 is definitely worth the investment.

If you’re looking for advanced protection and a lot of other great cybersecurity features, check out this list of the best premium antivirus products on the market.
