The best antivirus in the UK — and who each one suits

Start from your devices, not the marketing tier. Count every laptop, phone and tablet you want covered and note each operating system. That number decides the plan — a 'premium' tier you half-use is worse value than the right-sized plan. Then weigh the extras (VPN, password manager, identity monitoring) only if you'll actually use them, and always read the renewal price, not just the first-year offer.

Plans sold in the UK aren't the same as in the US. Norton's LifeLock identity-theft plans are US-only, McAfee's credit monitoring and credit freeze tools don't appear on its UK plans, and Avira's dark web monitoring is limited to residents of Germany. Prices are in pounds, and refund windows differ by brand — Norton lists 60 days on annual plans; McAfee, Avast and TotalAV list 30 days.

On Windows 11, Microsoft Defender already provides real-time protection, so a paid suite earns its place through scope and extras rather than basic scanning. Macs are lower-risk but not risk-free, and on phones the operating system limits what any security app can do — iPhone apps can't scan other apps at all — so mobile protection leans on web and scam-link warnings.

Built-in protection is a genuine baseline and may be enough for a single, well-maintained device. The case for paid is strongest at household scale: many devices, several operating systems, and one place to manage and check coverage — plus the bundled extras if you need them.
