Two of our editors ran five antivirus suites for 8 weeks across Windows 11 and macOS, throwing real-world malware samples, phishing pages, and ransomware simulators at them. These are the five we trust in 2026.
1Best detection rate, lightest footprint
Caught 100% of our malware samples with zero false positives, and idle CPU sits below 1%. Ransomware Remediation rolls back encrypted files automatically — the only suite that saved our test documents during the KnowBe4 simulation.
2Best heuristic engine, deepest controls
Top-2 detection in every independent lab (AV-Test, AV-Comparatives) for the last decade. Application Control + Safe Money browser are the most granular tools on the market. Note: US federal use restricted; consumer use is widely available.
3All-in-one with VPN, password manager, dark web monitoring
If you want one bill instead of three subscriptions, Norton 360 bundles antivirus + 50 GB cloud backup + VPN + password manager + identity monitoring. Detection is solid (99.7%) and the VPN is now run by surfshark infrastructure under the hood.
4Best for cleaning an already-infected machine
The tool every IT department reaches for when something slipped past the main AV. Heuristic engine finds adware and PUPs other tools ignore. Real-time protection is now competitive with the bigger suites — and the free scanner is still the gold standard for one-off cleanup.
5Best for older laptops and gaming PCs
Lowest CPU and RAM usage of any suite we tested. ESET’s signature-plus-heuristic engine has been quietly excellent for 20 years. Gaming mode actually works (zero notifications during a 3-hour Cyberpunk session). Less feature-rich than rivals, which is the point.
