Antivirus software in 2026 covers a lot more than the traditional virus scanning most people picture. Modern security suites deal with ransomware, phishing sites, malicious downloads, scam text messages and calls, and increasingly, identity and privacy risks that have nothing to do with a file infecting your hard drive.

Windows 11 also ships with Microsoft Defender Antivirus already turned on. That changes the question for a lot of readers: it is no longer “which antivirus should I buy” by default, but “do I need to buy one at all, and if so, what am I actually paying for?”

This guide compares 10 well-known consumer security products — free and paid — on the things that actually matter: independent lab-tested protection, ransomware and phishing defense, platform coverage, system impact, extra features like VPNs and password managers, and price, including what happens at renewal.

Quick Picks

These are use-case recommendations based on independent testing and current features — not a 1-to-10 ranking. No single product here is the right choice for everyone.

The 10 Antivirus Products at a Glance

Platform support, free options and independent testing status for each product, current as of September 2026.

Kaspersky note for US readers: the US Department of Commerce prohibited the sale and licensing of Kaspersky software in the United States, with enforcement taking effect in 2024. If you are in the US, check current availability before considering Kaspersky. It remains available in many other markets, including India.

1. Bitdefender Total Security

Best for: users who want strong multi-layer protection and a broad feature set without stepping up to a top-tier suite.

Bitdefender Total Security is Bitdefender’s flagship consumer suite, covering Windows, macOS, Android and iOS. The Individual plan is listed for up to 5 devices, with real-time malware protection, multi-layer ransomware protection, a dedicated password manager, and web attack and scam prevention. Not every feature is available on every operating system — some tools, like webcam monitoring, are Windows-specific, so check the feature comparison for your platform before buying.

Independent testing

AV-TEST’s June 2026 Windows 11 home-user test lists Bitdefender Total Security 27.0 with a Protection score of 6/6, Performance of 6/6 and Usability of 6/6 — an 18/18 total, which qualifies for AV-TEST’s TOP PRODUCT designation. That is a laboratory result for the specific version and test period AV-TEST evaluated, not an Etemora measurement or a guarantee of future results.

2. Norton 360

Best for: users who want antivirus combined with a VPN, password manager, scam protection and other security features in one subscription.

Norton 360 plans bundle antivirus, malware and ransomware protection, scam protection, a VPN, password manager, dark web monitoring and deepfake protection across every tier Norton currently sells, according to Norton’s own plan pages. The differences between tiers are mostly about device count, cloud backup storage, and whether LifeLock identity-theft features and parental controls are included.

Independent testing

AV-TEST’s June 2026 Windows 11 test lists Norton 360 with Protection 6/6, Performance 6/6 and Usability 6/6, an 18/18 total. As with every product here, this reflects one lab, one test period and one product version — not an Etemora finding.

3. ESET HOME Security

Best for: users who value a broad security suite and a lighter system footprint.

ESET renamed its consumer lineup to ESET HOME Security, sold in three tiers: Essential, Premium and Ultimate. All three cover PC, macOS, Android and iOS, with anti-phishing and Wi-Fi protection on every tier. VPN and encrypted-file storage are reserved for Premium and Ultimate, and Ultimate adds a larger VPN device allowance. Identity-monitoring features such as dark web scanning appear on the higher tiers.

Independent testing

AV-TEST’s June 2026 test lists ESET Security Ultimate 19.1 with Protection 6/6, Performance 6/6 and Usability 6/6, an 18/18 total. That lab-tested product name refers to the specific build AV-TEST evaluated and does not necessarily map one-to-one to ESET’s current commercial HOME Ultimate plan naming — check ESET’s own site for what a specific plan includes today.

4. McAfee Total Protection

Best for: households that need multi-device protection and identity-monitoring features in one plan.

McAfee Total Protection currently covers Windows, macOS, Android, iOS and ChromeOS, sold in 1, 3 and 5-device tiers according to McAfee’s own listings. It sits alongside McAfee’s broader McAfee+ lineup, which leans further into identity and privacy protection; Total Protection is positioned as McAfee’s core device-and-identity plan rather than its most premium tier.

Independent testing

AV-TEST’s June 2026 test lists McAfee Total Protection 1.37 with Protection 6/6, Performance 6/6 and Usability 6/6, an 18/18 total.

5. Avast

Best for: users looking for a genuinely free antivirus option with the choice to upgrade later.

Avast Free Antivirus, delivered through the Avast One app, covers Windows, macOS, Android and iOS. The free tier includes real-time file and behavior protection, ransomware shield, a Wi-Fi network inspector, firewall, and scam-site blocking, plus a time-limited VPN trial. Paid tiers — Avast Premium Security and Avast Ultimate — add unlimited VPN, cleanup tools and broader privacy features. The free and paid feature sets are genuinely different; do not assume the free version includes everything Avast sells.

Independent testing

AV-TEST’s June 2026 test lists Avast Free Antivirus 26.4 & 26.5 with Protection 6/6, Performance 6/6 and Usability 6/6, an 18/18 total. AV-Comparatives also includes Avast in its Real-World Protection testing; refer to the current factsheet for detailed figures.

6. AVG Antivirus

Best for: users wanting free protection with a familiar, straightforward consumer security app.

AVG Antivirus Free (AVG is owned by the same parent company as Avast, and the two products share underlying technology) covers Windows, macOS, Android and iOS, with real-time protection, multi-layer security, email and Wi-Fi protection, and ransomware protection at no cost. Paid upgrades — AVG Internet Security and AVG Ultimate — add firewall enhancements, webcam protection and broader privacy tools depending on the tier.

Independent testing

AV-TEST’s June 2026 test lists AVG Antivirus Free 26.4 & 26.5 with Protection 6/6, Performance 6/6 and Usability 6/6, an 18/18 total.

7. TotalAV

Best for: users looking for a simple consumer antivirus suite with additional privacy and cleanup tools alongside it.

TotalAV sells three main tiers — TotalAV Plus (antivirus), Internet Security (adds VPN) and Total Security (its most complete consumer bundle) — across Windows, Mac, Android and iOS. TotalAV also sells separate privacy products such as Total Password and Total Adblock. It is worth being clear that TotalAV’s system-optimization and cleanup tools are separate from its core malware-protection engine; one does not substitute for the other.

Independent testing

AV-TEST’s June 2026 test lists Protected.net TotalAV 6.6 with Protection 6/6, Performance 5.5/6 and Usability 6/6, a 17.5/18 total — still above AV-TEST’s 17.5-point threshold for its TOP PRODUCT award. Separately, AV-Comparatives’ February–May 2026 Real-World Protection report included TotalAV Premium among products that received that test period’s highest award tier. These are two different laboratories with different methodologies and should not be combined into a single score.

8. Kaspersky

Best for: users who want a broad security suite, where it is legally available to buy and use.

Kaspersky Premium covers Windows, macOS, Android, iOS and Linux, with unlimited VPN, a password manager, identity protection and performance tools bundled in on the flagship tier. Availability is the key issue for US readers: the US Department of Commerce prohibited the sale and licensing of Kaspersky antivirus products in the United States, with the prohibition on new sales and updates taking effect in 2024. If you are in the US, verify current legal availability before considering Kaspersky. It remains sold in many other markets, including India, subject to each country’s own rules.

Independent testing

AV-TEST’s June 2026 test lists Kaspersky Premium 21.24 with Protection 6/6, Performance 6/6 and Usability 6/6, an 18/18 total. Independent lab performance does not change the regional legal-availability situation described above.

9. F-Secure

Best for: users who want antivirus combined with privacy-focused features like VPN and identity monitoring.

F-Secure Total bundles antivirus, a VPN, password manager and identity-monitoring tools across Windows, macOS, Android and iOS. F-Secure’s own pricing page lists tiers by device count — 1, 3 or 5 devices — across 1-year and 2-year terms, with per-device cost dropping as device count rises.

Independent testing

AV-TEST’s June 2026 test lists F-Secure Total with Protection 6/6, Performance 6/6 and Usability 6/6, an 18/18 total.

10. Microsoft Defender Antivirus

Best for: Windows users who want built-in antivirus protection without purchasing another security suite.

Windows 11 includes Microsoft Defender Antivirus as part of Windows Security, active from the moment you set up the device. It provides real-time protection, cloud-delivered protection that checks suspicious files against Microsoft’s threat intelligence, an integrated firewall, and SmartScreen, which warns about malicious sites, downloads and apps. Windows Security also includes ransomware protection features such as Controlled Folder Access, which restricts which apps can modify protected folders.

Defender is separate from broader Microsoft 365 security features aimed at organizations; for a home user, what matters is the antivirus and Windows Security functionality described here, which is available at no extra cost on any Windows 11 device.

Independent testing

AV-TEST’s June 2026 test lists Microsoft Defender Antivirus 4.18 with Protection 6/6, Performance 5.5/6 and Usability 6/6, a 17.5/18 total — enough to qualify for AV-TEST’s TOP PRODUCT award. Full protection and usability points, with a 5.5/6 performance score, means Defender showed a small measurable system-resource impact relative to a perfect score in that specific test round — not that it performed poorly. AV-Comparatives also includes Microsoft Defender in its Windows testing; check its current factsheet for detail.

Free Antivirus vs. Paid Antivirus: What’s the Difference?

Free antivirus products from Avast, AVG and Microsoft Defender all provide meaningful core malware protection, backed by independent lab results in the table above. The gap between free and paid is mostly about what surrounds the antivirus engine, not the engine itself.

Paid suites typically add a VPN, password manager, identity or dark-web monitoring, parental controls, more advanced ransomware protection layers, cloud backup and centralized multi-device management. None of that is automatically “more secure” — it is additional functionality that some users need and others do not.

If you already use a separate password manager and VPN, and you do not need identity monitoring or parental controls, a free antivirus product plus good habits may be genuinely sufficient. If you want everything under one subscription and one interface, a paid suite can be worth the convenience.

Do You Need Antivirus Software on Windows 11?

Not automatically. Microsoft Defender Antivirus is on by default on Windows 11, scored well in AV-TEST’s June 2026 evaluation, and requires no setup or purchase. For a single Windows PC with reasonably careful browsing habits, built-in protection can be enough.

Third-party software becomes more useful when you need things Defender does not provide on its own: a VPN, a password manager, identity or dark-web monitoring, parental controls, extra scam-call and text protection, or centralized management across a mix of Windows, Mac and Android devices. If you only have a Windows PC and do not want those extras, there is no requirement to replace Defender with a paid product.

Best Antivirus Software by Use Case

Best Antivirus for Windows

Windows 11 comes with Microsoft Defender Antivirus active by default, and it tested well in AV-TEST’s June 2026 evaluation. That covers core protection for most Windows users without a purchase. Third-party Windows antivirus products from Bitdefender, Norton, ESET, McAfee, Avast, AVG, TotalAV, Kaspersky and F-Secure add features like VPNs, password managers and identity monitoring on top of their own antivirus engines. Windows users are not required to buy one of these; the decision comes down to whether you want those extra features bundled in.

Best Antivirus for Mac

macOS includes its own built-in security mechanisms, including Gatekeeper and XProtect, which check apps and files for known malware. That reduces — but does not eliminate — the value of third-party protection. Mac-focused malware, phishing sites and malicious downloads do exist, and third-party antivirus can add web protection, phishing filtering and privacy tools that macOS does not provide on its own.

Every product in this comparison that lists Mac support (Bitdefender, Norton, ESET, McAfee, Avast, AVG, TotalAV, Kaspersky and F-Secure) offers a macOS client. Windows test results should not be treated as evidence of Mac performance; AV-TEST publishes separate Mac-specific testing, and that is the more relevant source if Mac performance is your priority.

Best Antivirus for Android

Android security apps focus on scanning installed and sideloaded apps for malware, flagging malicious or deceptive apps, blocking phishing links and unsafe websites, and in some cases adding anti-theft features like remote lock or locate. Because Android allows installing apps from outside the Play Store, app-based threats are a bigger practical concern than on iOS.

Bitdefender, Norton, ESET, McAfee, Avast, AVG, TotalAV, Kaspersky and F-Secure all offer Android apps with some combination of these features. Android and iOS do not have identical security needs, largely because of how differently the two platforms restrict app installation and system access.

Best Antivirus for iPhone

iOS antivirus works differently from Windows or Android antivirus because of how Apple restricts app permissions. iOS apps, including security apps, do not get unrestricted system-level scanning access the way a traditional Windows antivirus engine does. As a result, iPhone security apps from vendors in this comparison focus on phishing protection, malicious-website blocking, Wi-Fi network safety, identity or dark-web monitoring, and VPN — not traditional file-system virus scanning.

That does not make these apps pointless; phishing links and unsafe Wi-Fi networks are real risks on iPhone. It does mean you should judge an iOS security app on those specific protections rather than expecting it to behave like desktop antivirus.

What Does Antivirus Software Actually Protect You From?

Modern antivirus and security suites are built to catch several distinct categories of threat:

• Viruses and trojans — malicious code that infects files or disguises itself as legitimate software.
• Ransomware — malware that encrypts your files and demands payment; most products here include a ransomware-specific protection layer.
• Spyware and adware — software that tracks activity or injects unwanted advertising.
• Malicious downloads — files that carry malware, often flagged before they finish downloading.
• Phishing and malicious websites — fake login pages and scam sites designed to steal credentials or payment details.
• Potentially unwanted applications (PUAs) — software that is not strictly malware but behaves in unwanted or deceptive ways.

Antivirus is not a complete substitute for basic security hygiene. Keeping software updated, using strong and unique passwords, enabling multi-factor authentication, browsing carefully, and keeping backups of important files all matter alongside, not instead of, antivirus protection.

Antivirus vs. VPN: What’s the Difference?

These solve different problems and one does not replace the other.

Antivirus protects your device against malicious software and security threats — scanning files, blocking malware, and flagging dangerous sites and downloads.

A VPN encrypts the network traffic between your device and a VPN server, which can help protect your privacy on public or untrusted networks. It does not scan files for malware and does not stop you from downloading something malicious.

Several products in this comparison, including Norton, Kaspersky and F-Secure, bundle both into one subscription. That is a convenience decision, not a sign that either tool alone is incomplete.

Antivirus vs. Password Manager

Antivirus protects devices. A password manager generates, stores and autofills your credentials so you can use strong, unique passwords for every account without memorizing them. A password manager does not scan for malware, and antivirus does not manage your logins.

Bitdefender, Norton, McAfee, Kaspersky, F-Secure and ESET’s higher tiers all bundle a password manager. If you want a more full-featured, standalone password manager, see our Best Password Managers guide.

How We Compared These Antivirus Products

This is a research-based comparison, not a benchmark study. Etemora did not independently reproduce AV-TEST’s or AV-Comparatives’ laboratory tests, and we do not present their results as our own measurements.

Our comparison considers: independent laboratory testing results, protection features (malware, ransomware, phishing, web protection), platform coverage, privacy tools, VPN and password-manager inclusion, identity-monitoring features, device limits, pricing and renewal pricing where published, ease of use, plan complexity, and overall fit for different types of users.

Test results referenced throughout this article come from AV-TEST’s Windows 11 home-user evaluations and AV-Comparatives’ Real-World Protection Test series, and apply to the specific product versions and test periods those labs evaluated. We do not combine scores from different laboratories into a single artificial number, because their methodologies are not directly comparable.

More about our approach is in How We Review.

How Much Does Antivirus Software Cost in 2026?

Free antivirus — including Microsoft Defender, Avast Free Antivirus and AVG Antivirus Free — costs $0. Paid antivirus is typically sold as an annual subscription, with pricing shaped by device count, plan tier, first-year promotions, country and billing term.

Every paid product in this comparison advertises a first-year or promotional price that is usually lower than what you pay at renewal. Where a vendor’s page did not clearly publish a renewal figure, we say so rather than inventing one — renewal pricing varies and should be confirmed at checkout before you buy.

What to Look for in Antivirus Software

Malware protection

The core function. Independent lab scores are the most reliable public signal of how well a product actually detects and blocks malware.

Ransomware protection

Look for a dedicated ransomware layer, not just general malware detection — most products in this comparison include one.

Phishing protection

Web and email filtering that blocks known phishing and scam sites before you can enter credentials.

Web protection

Blocking malicious downloads and dangerous websites in real time as you browse.

Independent testing

Check current AV-TEST and AV-Comparatives results rather than relying on a vendor’s own marketing claims.

System performance

Lab performance scores indicate how much a product slows down everyday tasks like copying files or launching applications.

Device coverage

Confirm which operating systems and how many devices a specific plan actually covers — this varies a lot between tiers.

Privacy features

Dark-web or identity monitoring, webcam protection, and data-removal tools where offered.

VPN

Check whether it is unlimited or capacity-limited, and whether it is included or a separate add-on.

Password manager

Useful if you do not already use a dedicated one; redundant if you do.

Identity monitoring

Dark-web scanning and breach alerts, usually reserved for higher tiers.

Parental controls

Content filtering and screen-time tools, available on select plans from McAfee, Norton and others.

Price and renewal

Always check the renewal price, not just the first-year offer.

Customer support

Live chat, phone support and response times vary by vendor and plan tier.

Common Antivirus Mistakes to Avoid

1. Buying based only on the first-year price. The renewal rate is usually the number that matters over time.
2. Ignoring renewal pricing entirely. Check it before you subscribe, not after the first charge.
3. Installing multiple real-time antivirus programs at once. They can conflict and cause performance problems.
4. Assuming a VPN is antivirus. They protect against different things.
5. Assuming antivirus makes phishing impossible. Web protection helps, but you still need to check links and sites yourself.
6. Ignoring software updates. Unpatched software is a common entry point regardless of your antivirus.
7. Not using multi-factor authentication. It protects accounts even if a password leaks.
8. Not keeping backups. Ransomware protection reduces risk; backups are your recovery plan if something still gets through.
9. Buying features you do not need. A premium suite with parental controls and identity monitoring is wasted spend if you live alone and do not need either.
10. Assuming a test result on one operating system applies to every platform. Windows results do not tell you how a product performs on Mac, Android or iOS.

Should You Install More Than One Antivirus?

No, not as two full real-time antivirus programs running at the same time. Two real-time engines competing to scan the same files can interfere with each other, cause false positives, and slow the system down without meaningfully improving protection.

If you want a second opinion, an on-demand scanner — one you run manually to check for something a full-time engine might have missed — is different from running two real-time antivirus products simultaneously, and is generally safe to use occasionally.

Final Recommendations

If you want a broad paid security suite: Bitdefender or Norton.

If you want built-in Windows protection: Microsoft Defender Antivirus.

If you want privacy and security features together: ESET or F-Secure.

If you want family multi-device coverage: McAfee.

If you want free protection: Avast, AVG or Microsoft Defender.

If you want many bundled features in one suite: Norton, Bitdefender or McAfee.

There is no universal ranking here on purpose. The right choice depends on your operating system, number of devices, budget, privacy needs, and whether you actually want a VPN, password manager, identity monitoring or parental controls bundled in.

Final Verdict: Best Antivirus Software in 2026

There is no single antivirus product that every reader needs. That is the most honest starting point for a comparison like this one, and independent testing backs it up: in AV-TEST’s June 2026 Windows 11 evaluation, the majority of products covered here — including free options — scored a full 18 out of 18 points across protection, performance and usability.

Microsoft Defender Antivirus, built into every Windows 11 device at no extra cost, scored 17.5 out of 18 in that same test, with full marks for protection and usability and a small measured performance impact. For a lot of Windows users, that is genuinely enough. You are not obligated to buy a third-party product just because it exists.

Where paid suites earn their price is in what they add beyond core antivirus: a VPN, a password manager, identity or dark-web monitoring, parental controls, cloud backup, and centralized management across a mix of devices. Bitdefender, Norton, ESET, McAfee, Avast, AVG, TotalAV, Kaspersky and F-Secure each combine those extras differently, at different price points, with different device limits.

If you want the broadest feature set with a strong independent testing record, Bitdefender and Norton are reasonable starting points. If your budget is $0, Avast, AVG and Microsoft Defender all tested well without costing anything. If you are outside the US and want the deepest bundled feature set, Kaspersky is worth a look, subject to your local availability. If privacy tools matter most to you specifically, F-Secure is built around that idea more directly than most competitors.

The decision that actually matters is not which product has the longest feature list. It is which combination of platform coverage, extra tools and price fits how you actually use your devices — and whether you are willing to pay for features you might not use just to get the ones you do.
