The short answer: for most home users, no. But there's nuance worth understanding.
Windows Defender is genuinely good now
Windows Defender — the free antivirus built into Windows 10 and 11 — has been transformed over the past five years. In independent testing by AV-TEST and AV-Comparatives, it consistently scores 99%+ detection rates, matching or exceeding many paid products. The days when Windows needed third-party antivirus are largely over.
What paid antivirus adds
Most paid antivirus packages (Norton, McAfee, Kaspersky, Bitdefender) add: VPN services, password managers, parental controls, dark web monitoring, identity theft insurance, and multi-device coverage. If you need these features, the bundle may offer value. If you just want malware protection, you're paying for things you may not need.
What matters more than antivirus
- Keeping Windows fully updated
- Not clicking suspicious links or email attachments
- Using strong unique passwords and 2FA
- Maintaining a backup
- Using a modern browser (Chrome, Firefox, Edge) with safe browsing enabled
What to avoid
Avoid free third-party antivirus products — many monetise through data collection, browser modification, and bundled software. And be very suspicious of pop-up warnings claiming your computer is infected and asking you to download something — these are almost always fake.
