Best Antivirus Software for Australia (2026)

Kaspersky is our clear #1 pick for antivirus in Australia in 2026. In independent testing by AV-TEST and AV-Comparatives — the two most respected antivirus testing labs in the world — Kaspersky consistently achieves 99.9%+ real-world malware detection rates with near-zero false positives. No other consumer antivirus matches this combination of accuracy and system lightness.

For Australian users, Kaspersky offers a dedicated ANZ program with locally relevant pricing, support, and licensing. Their Kaspersky Standard, Plus, and Premium plans scale from basic antivirus protection for one device to comprehensive security suites covering up to 10 devices across Windows, Mac, iOS, and Android — perfect for families with mixed device ecosystems.

Kaspersky Premium (their flagship offering) adds identity theft protection, password manager, parental controls, VPN (unlimited data), and 24/7 premium support. The VPN alone, included at no extra charge, covers 5 devices with servers in 60+ countries — making it excellent value versus purchasing VPN and antivirus separately.

The Safe Money feature provides a secured browser environment specifically for online banking and shopping — especially relevant for Australian consumers doing internet banking. All transactions in Safe Money mode are protected against keystroke loggers, screen capture malware, and man-in-the-browser attacks.

System performance impact is minimal. Kaspersky's engine is engineered for low resource usage, making it suitable for older machines without noticeable slowdown. In our tests on a Windows 11 laptop, CPU usage during real-time protection averaged under 1% at idle. Scans are fast and can be scheduled during off-hours automatically.

McAfee Total Protection is our runner-up pick for Australian users in 2026. Its standout feature is unlimited device coverage on the Premium plan — one subscription protects every Windows PC, Mac, iPhone, iPad, and Android device in your household with no per-device fees. For large Australian families with 5+ devices, McAfee often delivers better overall value than Kaspersky.

McAfee's Identity Protection features are particularly strong — continuously monitoring the dark web for your personal information including email addresses, Medicare numbers, banking credentials, and passport data. Australian users receive alerts immediately if their data appears in a known breach, with guided remediation steps.

Detection rates are very strong at 99.5%+ across independent tests, though marginally below Kaspersky. The interface is clean and easy to use, making it an excellent choice for less technical users who want reliable protection without configuration complexity.

ESET has earned a reputation as the go-to antivirus for technical users and IT professionals. ESET NOD32 and the more complete ESET Internet Security deliver exceptional detection with the lowest system footprint of any major antivirus suite — meaning your PC or Mac runs at full speed even when protection is active. Trusted by 110 million users across 200+ countries.

ESET Internet Security adds a bidirectional firewall, network attack protection, anti-phishing, webcam protection, and parental controls. For Australian users who primarily want fast, reliable protection without the feature bloat of larger suites, ESET is an excellent choice. The multi-year licence discounts also make it one of the most cost-effective long-term options.
