Best Anti Virus Software in 2026

If you want our short answer to "which anti virus software is best", Bitdefender is it for most people. It earned AV-Comparatives' Top-Rated Product award for 2025, plus Silver in Real-World Protection and Bronze for both Malware Protection and low false positives. That is a consistent record across the tests that matter.

Pricing on Bitdefender's own US page starts with Antivirus Plus at $29.99 for the first year, covering up to 3 devices. Total Security costs $59.99 for one person on 5 devices, and the family version covers 5 members and 25 devices for $79.99. All of those are first-year prices, and Bitdefender says renewal pricing applies after that.

The catch is the upsell ladder. Premium Security, Ultimate Security and Ultimate Security Plus add VPN and identity features, and the top family plan reaches $179.99 for the first year. Most households only need Antivirus Plus or Total Security.

Norton is the name many people already know, and the lab results back it up. AV-Comparatives gave Norton Antivirus Plus Top-Rated status for 2025, Gold in Real-World Protection and Silver for performance, which means it caught threats without slowing PCs down much.

Norton's US product page lists AntiVirus Plus at $59.99 for the first year for 1 PC, Mac, tablet or phone, with 2 GB of cloud backup and a password manager. Norton 360 Deluxe is listed at $119.99 for the first year and covers 5 devices with a VPN and dark web monitoring. Norton runs frequent sales, so check the live price at checkout.

The honest weakness is cost and noise. Norton pushes its LifeLock identity plans hard, and the $189.99 Select Plus bundle is more than most families need. If you only want malware protection, AntiVirus Plus is enough.

Before you pay for anything, know that Windows 11 already comes with antivirus. Microsoft says Defender Antivirus is real-time, always-on protection and that you do not have to pay extra for it. It sits inside the Windows Security app alongside SmartScreen warnings for risky sites and downloads, and Smart App Control, which tries to predict which apps are safe to run.

For a careful user who keeps Windows updated and avoids sketchy downloads, Defender is a reasonable baseline. It was part of AV-Comparatives' 2025 test field of 19 products.

What you give up is breadth. Defender does not protect your Mac or your kids' phones, and it did not make the 2025 Top-Rated list. If you want parental controls, a VPN or protection on several kinds of devices, a paid suite still makes sense.

ESET is a favorite of people who want security software that stays out of the way. ESET HOME Security Essential earned AV-Comparatives' Top-Rated Product award for 2025, alongside Bitdefender and Norton.

The US site splits ESET into three annual plans. Essential covers antivirus, safe payments, anti-phishing and Wi-Fi protection. Premium adds unlimited VPN traffic and file encryption, and Ultimate adds identity protection and a router VPN. ESET offers a free 30-day trial with no credit card required, which is a fair way to see whether it suits an older laptop.

The annoyance is that the US plan pages do not show prices until you start checkout, so you have to click through to compare. Resellers often list ESET keys cheaper, but buying from ESET directly keeps renewals simple.

Malwarebytes built its reputation as the tool you run when something already went wrong. The free version is still a popular second-opinion scanner, and the paid Standard plan adds full-time protection, safe browsing and a scam and ad blocker.

Its pricing page lists Standard from $59.99 a year for 3 devices and Plus, which adds a VPN, from $79.99 a year. A Family Standard plan covers 10 devices for $119.99 a year. Malwarebytes works on PC, Mac, Android and iOS, and it offers a 60-day money-back guarantee.

The honest catch: Malwarebytes Premium was in AV-Comparatives' 2025 test group but did not earn Top-Rated status. We would use it as a cleanup tool or a second layer rather than as the only protection on a family PC.

Avast Free Antivirus was one of AV-Comparatives' Top-Rated products for 2025, and it took Gold in the performance category, which is impressive for a free tool. Its sister product AVG AntiVirus Free earned the same awards.

If you want more, Avast Premium Security shows $49.08 for the first year against a $77.99 renewal price for one Windows PC plus one phone. Avast offers a 30-day free trial on Windows with no credit card needed.

There is a real trust issue to weigh. In 2024 the FTC finalized an order banning Avast from selling web browsing data for advertising and requiring a $16.5 million payment, after charges that its Jumpshot subsidiary sold browsing data collected through its software. The order adds privacy obligations going forward, but some readers will reasonably choose a different brand.

Trend Micro is worth a look for households with a mix of devices, Chromebooks included. Maximum Security covers up to 5 devices on Windows, Mac, Android, iOS and Chromebook, according to Trend Micro's product page.

The standout feature is Pay Guard, which Trend Micro says checks that banking sites are legitimate before you sign in. The page also lists ransomware defense and web threat blocking. Trend Micro's US store shows $74.95 for the first year on 5 devices, down from $104.95.

On the downside, Trend Micro Internet Security was in AV-Comparatives' 2025 test field but did not earn Top-Rated status. You also pay more up front than with Bitdefender or Avast.

Avira suits people who want a free antivirus that also covers a Mac and phone. Avira Free Security is described on its site as a free, all-in-one solution, and the antivirus runs on PC, Mac, Android and iOS. A Software Updater for PC is also part of the lineup.

In AV-Comparatives' 2025 report, Avira Free Antivirus earned Bronze in Real-World Protection, sharing that spot with Kaspersky and McAfee. That is solid for a free product, though it did not make the overall Top-Rated list.

The trade-off is the usual one for free tools. Avira steers you toward Avira Prime for its VPN and premium apps, and you need to go through the store to see current pricing. Avira also notes that Windows versions older than 10 are no longer supported.
