Should I pay for antivirus?

1. The short answer

For most home users in 2026, the antivirus that already came with your computer is enough — and it’s free. You do not need to buy a separate antivirus program to be reasonably safe. What you do need is a few good habits, which are worth more than any software you can buy. More on those below.

That’s not me being cheap on your behalf, and it’s not Microsoft’s marketing talking either — Microsoft is in the business of selling security, not talking you out of it. This is my own professional opinion after fifteen-plus years of doing this for a living. What Microsoft will tell you is that Defender is built in, free, and always running. What the independent testing labs will tell you is that it scores right up with the paid products. I draw the obvious conclusion from those two facts; you’re free to draw your own.

2. Why the built-in protection is genuinely good now

This used to be different. Ten or fifteen years ago the security built into Windows was weak, and buying something extra made sense. That changed. Here’s where things actually stand:

• Microsoft Defender Antivirus is built in, free, and already turned on. In Microsoft’s own words about Windows 11: “Your Windows 11 device comes with Microsoft Defender Antivirus built-in. You don’t have to pay extra for this antivirus protection.” (It ships on Windows 10 the same way.) You don’t install it — it runs in the background and updates itself automatically, as long as you don’t have another antivirus installed. (Microsoft — Windows security)
• It’s real-time and always on. Microsoft describes Defender as “real-time, always-on antivirus protection” — it’s scanning quietly as you use the machine, not something you have to remember to run. (Microsoft — Windows security)
• The independent labs rate it right up with the paid products. AV-TEST, one of the respected outfits that tests antivirus software, gave Microsoft Defender a perfect 6.0-out-of-6.0 protection score in each of its three most recent consumer tests — December 2025, February 2026, and April 2026 — and named it a “Top Product” every time. (AV-TEST)

So if you have a reasonably up-to-date Windows PC, you already own solid antivirus. Paying for another one on top usually just adds a second program fighting for the same job.

On a Mac, the same is true. macOS has malware protection built in — a piece called XProtect that scans for known malware and updates its list quietly in the background, plus Gatekeeper, which checks that apps you download are from a trusted source before they’ll open. It’s on by default and you don’t manage it. (Apple Support) Macs get fewer viruses than PCs to begin with, and for most people Apple’s built-in protection is plenty.

3. So when does paying actually make sense?

Paid antivirus isn’t a scam — it’s just that what you’re paying for, these days, usually isn’t the virus scanning (yours is already good). You’re paying for the extra features bundled around it. Those can be worth it for the right person. A paid suite might include things like:

• A password manager to store your logins.
• A VPN for using public Wi-Fi.
• Identity or “dark-web” monitoring that alerts you if your info shows up in a data breach.
• Parental controls and coverage for a whole family’s worth of phones, tablets, and computers under one subscription.

If you specifically want those extras and you’d rather have them bundled in one place, a paid product can be a reasonable buy. Just go in knowing that’s what you’re paying for — the convenience of the bundle — not because your computer is unprotected without it. And a lot of those pieces (a good password manager, for instance) are available on their own, often free, if you’d rather not buy the whole package.

Two honest cautions, without naming names:

• Watch the auto-renewal price. Many paid antivirus products are cheap the first year and jump sharply on renewal. It’s worth checking what you’re actually being charged each year.
• Don’t run two antivirus programs at once. They’ll interfere with each other and can slow your machine down. If you install a paid one, it generally turns the built-in one off automatically — which is fine — but don’t try to stack a second paid product on top.

4. The part that matters more than any software

Here’s the thing most “just buy this antivirus” advice skips: the biggest risk to your computer isn’t a virus your antivirus missed — it’s someone talking you into letting them in. No antivirus stops you from typing your password into a fake login page, or handing remote control of your computer to a stranger who called and said he was “Microsoft.” (That last one is common enough that I wrote a whole page on it — see Spam & scam phone calls: what to do.)

The habits that actually keep you safe are simple and free:

• Keep your computer’s updates turned on. The updates patch the security holes that malware uses. This matters more than which antivirus you run.
• Be careful what you install. Most infections come from downloading something you shouldn’t have — a “free” program, a fake update, an email attachment you weren’t expecting.
• Use strong, different passwords, and turn on two-step verification for your email and bank. It’s the single best lock there is.
• Slow down when something feels urgent or scary. Pressure is the trick. A real problem waits five minutes while you check.

Do those things and the built-in antivirus, and you’re in better shape than most people paying for a fancy suite they don’t use right.

5. The bottom line

• Most people: the free, built-in protection on your Windows PC or Mac is enough. Save your money.
• If you want extras like a password manager, VPN, or family/identity monitoring: a paid suite can be a fair buy — for those features, not because you’re unprotected.
• Either way: your habits matter more than your software. Updates on, careful downloads, strong passwords, and a healthy pause when something feels off.

6. Not sure what you’ve got, or whether it’s set up right?

If you’d like someone to check that your antivirus and updates are actually on and working — or you just want a straight answer about whether that renewal is worth it — that’s exactly the kind of thing you can ask us.
