Paid antivirus in 2026: is it still worth paying? (a pro's view)

"I've paid €60 a year for 10 years — can I stop now?" — it's a question my clients ask me at least once a week. The answer has changed over the last few years, and it's no longer the same as it was in 2015.

Here's a clear rundown of what has changed, what's still true, and what I recommend to my clients in Le Cannet, Cannes and Mougins today.

The landscape has changed: Windows Defender has become serious

For a long time, the antivirus built into Windows was a joke. Slow, ineffective, consistently beaten by third-party solutions. Microsoft has invested heavily and the situation has completely changed since Windows 10 (and even more so with Windows 11).

In recent independent tests (AV-TEST, AV-Comparatives), Windows Defender (renamed "Windows Security") achieves detection rates on a par with the best paid antivirus programs. It's built into the system, so it's fast, and it's completely free.

Is Windows Defender really enough?

For 90% of the home users I help: yes, provided you also follow a few common-sense rules alongside it:

• Install Windows updates regularly (that's what patches the security holes)
• Don't click links in suspicious emails (see my article on scam emails)
• Only download software from official websites — never from "crack" sites or dodgy download sites
• Use an up-to-date browser (Chrome, Firefox, Edge) with an ad blocker such as uBlock Origin

If you follow these rules, Defender catches the vast majority. In the rare cases where it misses something, a paid antivirus would probably have missed it too.

And on a Mac?

On a Mac, the debate is even more clear-cut: for a home user who downloads their apps from the Mac App Store or directly from the software makers (Office, Adobe, etc.), macOS is designed to block almost all malware thanks to Gatekeeper and XProtect.

I still see clients with Norton or McAfee installed on their Mac, slowing the machine down without adding anything. Safe to remove in 95% of cases.

When a paid antivirus still makes sense

There are still cases where I do recommend a paid antivirus. Not for the detection engine itself, but for the extra features:

• Robust parental controls — for children or teenagers on the family computer. The built-in options are often less comprehensive.
• Built-in VPN — useful if you regularly work from public Wi-Fi (hotels, airports).
• Dedicated anti-phishing — extra protection at the browser level, useful for elderly or less confident users.
• Identity monitoring / dark web monitoring — for those who have already been caught up in a data breach.

In these cases, I'd lean towards Bitdefender or F-Secure, which stay light on the machine. Expect to pay €40-60 per year for the premium version.

The antivirus programs to avoid in 2026

Without naming brands as such, here are the types of antivirus I systematically uninstall for my clients:

• The ones that cripple performance: some "all-in-one" suites install 4-5 heavy services that start up with Windows. On a 5-7 year old PC, that's what's slowing things down, not the computer itself.
• The ones pre-installed as trial versions on new PCs: McAfee or Norton thrown in free for 30 days, then nagging you to renew. Uninstall as soon as the PC arrives.
• The "PC optimisers" dressed up as antivirus: CCleaner Pro, Advanced SystemCare, etc. They create more problems than they solve.
• The "100% free" antivirus programs that come out of nowhere: they fund their development by reselling your data or showing intrusive ads.

My recommendation for most home users

On a Windows PC: keep Windows Defender. Uninstall third-party antivirus programs, especially the pre-installed ones. Keep Windows up to date. If you want extra phishing protection for a less tech-savvy relative, add the free Malwarebytes Browser Guard extension to their browser.

On a Mac: nothing to install. macOS handles it. Just avoid dodgy download sites and the fake Flash/Java updates that pop up while you're browsing.

Special cases (parents with children, remote working on public Wi-Fi, elderly users): Bitdefender Total Security or equivalent, €40-60/year, but well chosen.
