It is a fair question, because for years we were all told to buy antivirus. The honest 2026 answer: for most careful people, the protection already built into Windows is enough, and what really keeps you safe is your own habits.

Windows Defender is genuinely good now

Microsoft Defender, built into Windows, has gone from a punchline to a genuinely strong, free antivirus. In independent lab tests it now scores alongside the big paid names for catching malware. It runs quietly in the background, updates itself, and costs nothing. For a careful user who keeps Windows updated, it covers the bases.

When paid antivirus is worth it

It is not useless, though. A paid suite can be worth it if:

  • You want extra features bundled in, like a VPN, a password manager, parental controls or identity monitoring, in one subscription.
  • You are protecting less cautious users, such as children or older relatives, where the extra warnings and web filtering help.
  • You want cross-device cover for a houseful of Windows PCs, Macs and phones from one place.

Names worth knowing if you go paid include Bitdefender and Norton. We will compare them honestly rather than just chasing the biggest commission.

What actually keeps you safe (free)

No antivirus saves you if you hand your details to a fake site or reuse one leaked password. The real protection is behaviour:

Bottom line: for most people on an up-to-date PC, Windows Defender plus good habits is enough. Pay for a suite only if you genuinely want its extra features, not out of fear.

What about phones? They need far less: stick to the official app stores and keep them updated. More in our devices and accounts section.
