Best Antivirus Software in 2026

What we mean by "best"

An antivirus program has one core job: catch malicious code before it runs, block it if it slips through, and undo the damage where possible. Everything else, a VPN, a password manager, dark web monitoring, is bundled convenience layered on top, not the reason the product exists. For this list we weighted three things: independent lab results from AV-TEST and AV-Comparatives over the past year, what a subscription actually costs once the first-year discount expires, and whether the bundled extras are genuinely useful or just padding to justify the price. Every price and feature below came from the vendor's own site or a specific pricing page checked in August 2026, cross-referenced against recent lab reports.

Bitdefender Total Security

Bitdefender's engine posted Top Product results from AV-TEST and an Advanced+ rating from AV-Comparatives through spring and summer 2026, a more consistent record than most competitors managed over that stretch. The Total Security individual plan runs $59.99 a year for five devices across Windows, macOS, Android, and iOS, with a 25-device family plan at $79.99. Real-time protection, ransomware remediation, a firewall, and a password manager are included, and the bundled VPN is capped at 200MB of encrypted traffic per device per day, enough to check email on public WiFi but not much more. It suits anyone who wants lab-verified detection without paying extra for a VPN they will rarely use at that data cap.

Norton 360

Norton also earned Top Product and Advanced+ marks in 2026 testing, and Gen Digital's shared threat-intelligence pool, built from Norton, Avast, and AVG telemetry, is part of why detection has stayed competitive across all three brands. Norton 360 Deluxe lists at $39.99 for the first year covering five devices, renewing at $124.99; Standard covers three devices with a lower renewal ceiling near $94.99. Unlike Bitdefender, Norton's VPN carries no data cap, and Deluxe adds 50GB of cloud backup plus parental controls. The jump from first-year price to renewal, often 60 to 140 percent, is steep enough to put a reminder on your calendar before it auto-renews.

McAfee+

McAfee+ Essential starts near $7 a month during its introductory period and covers five devices with antivirus, a capped VPN, and basic identity monitoring. The Premium, Advanced, and Ultimate tiers move to unlimited device coverage and add personal data removal from broker sites, bank and credit account monitoring, and identity theft coverage that scales up to $2 million on Ultimate. McAfee Total Protection also carried a Top Product rating from AV-TEST in mid-2026. The unlimited-device policy is unusual among mainstream vendors and makes McAfee+ worth a look for households running more than five or six connected devices, though the identity tools lean on US-specific data broker coverage.

Malwarebytes Premium

Malwarebytes built its reputation as a second-opinion cleanup tool, and the Standard plan still reflects that: $59.99 a year for three devices, antivirus only, no VPN. The Plus plan adds a VPN for $79.99 at three devices or $99.99 at five. Malwarebytes cites 99.9 percent detection against known malware and 99.2 percent against zero-day threats in third-party sample testing, and the product was included in AV-Comparatives' 2026 real-world protection round, though it did not land in that round's Advanced+ tier alongside Bitdefender and Norton. It fits someone who wants a lighter, less naggy interface than the big suites more than someone chasing the top lab score.

ESET HOME Security Premium

ESET prices by device count rather than a single flat tier: Premium runs $59.99 a year for one device up to $104.99 for ten, with the cheaper Essential tier skipping the password manager and file encryption Premium adds. ESET's Security Ultimate product posted a Top Product result from AV-TEST in June 2026. The bundled VPN carries unlimited traffic but limits simultaneous device connections to three or five depending on the license size purchased. ESET tends to run lighter on system resources than Norton or McAfee, which makes it a reasonable fit for older laptops, though its identity and cloud-backup features are thinner than Norton's or McAfee's.

Microsoft Defender

Defender already runs on every Windows 10 and 11 machine at no extra cost, and AV-TEST's June 2026 results gave it a Top Product rating with full marks on protection and usability, though performance scored slightly lower at 5.5 of 6. Microsoft has discontinued Defender's built-in VPN; a Microsoft 365 Personal or Family subscription now adds identity theft monitoring, dark web scanning, and up to $1 million in identity theft insurance instead, and that identity coverage is limited to US subscribers. For a single, well-maintained Windows PC with no VPN or identity needs, Defender is a legitimately defensible free choice. It just is not a full security suite on its own.

Avast One (Premium Security)

Avast Premium Security covers one PC or Mac plus one mobile device for $77.99 a year at regular price, or ten devices for $99.99. It earned an Advanced+ rating in AV-Comparatives' 2026 real-world protection test, and its scam-detection layer, covering email, SMS, and deepfake video, has expanded further than most competitors offer. Avast shares its parent company, Gen Digital, with Norton and AVG, so the underlying detection engine has a lot in common across all three brands even though the interfaces and bundled extras differ. Ransomware protection and webcam blocking are included at every paid tier.

AVG Ultimate

AVG Internet Security runs about $8.33 a month after an introductory year, covering up to ten devices with ransomware protection, a firewall, and phishing-site blocking. AVG Ultimate adds a VPN, AVG TuneUp performance tools, and AntiTrack privacy protection for roughly $12.50 a month at post-introductory pricing. Like Avast, AVG earned an Advanced+ rating in AV-Comparatives' spring 2026 round and shares Gen Digital's detection engine. It is essentially Avast with different branding and a different bundle, so the choice between them comes down to which extras, TuneUp versus Avast's scam-detection tools, you would actually use.

A note on Kaspersky: despite a strong lab-testing history, Kaspersky remains barred from sale in the United States. The Commerce Department's Bureau of Industry and Security prohibited new US transactions in mid-2024 and cut off software and signature updates that September, and that prohibition is still in force in 2026. It is not part of this list for US buyers, and we would not recommend installing or renewing it here regardless of its scores elsewhere.

How to choose

If you want the strongest independent lab record and do not need a full-strength VPN, Bitdefender is the safest default. If you already run Windows and mainly need a competent baseline, Microsoft Defender covers a single well-maintained PC for free. If identity theft protection with high coverage limits matters most, look at McAfee+ Ultimate or Norton with LifeLock. Households with more than five or six devices should weigh McAfee+'s unlimited coverage against ESET's ten-device ceiling. An older or resource-constrained laptop runs better under ESET than under the heavier suites. If you want antivirus that stays out of the way and skips the upsells, Malwarebytes' Standard plan is the calmest option, though it will not match Bitdefender or Norton on lab scores.

The verdict

There is no single correct antivirus for everyone, but the field narrows fast once you rule out weak lab scores and unclear pricing. Bitdefender earns the top spot here for combining consistent detection with a fair price at five devices. Norton is the strongest runner-up if you want an uncapped VPN and backup bundled in, and Microsoft Defender is a genuinely reasonable zero-cost baseline for a single Windows machine that you keep updated. Whatever you pick, mark your renewal date, because the biggest risk to your wallet here is not malware, it is forgetting that the introductory price was never permanent.
