Both scored full marks in AV-TEST's August 2026 round and both won AV-Comparatives' Top-Rated award for 2025, so protection is a tie. Pick Norton for bundled backup and LifeLock identity options, Bitdefender for a lighter entry tier and wide device coverage.

Key takeaways
- Protection is a tie: both scored 6/6/6 with AV-TEST in July and August 2026 and both were Top-Rated by AV-Comparatives for 2025.
- Choose Norton 360 if you want cloud backup for a Windows PC and the option of LifeLock identity theft protection in the same bill.
- Choose Bitdefender if you want a cheaper entry plan across Windows, Mac, Android and iOS, or a family plan covering many devices.
- Both quote first-year prices and renew automatically at a higher price. Set a reminder before the renewal date.
- If you only use one Windows PC, the free Microsoft Defender scored the same 6/6 for protection. You may need neither.
First: do you need either one?
In the AV-TEST round for July and August 2026, Microsoft Defender, which comes free with Windows, scored the maximum 6 out of 6 for protection, just like Bitdefender and Norton. So the reason to pay is the layer around the malware engine: web and scam filtering in every browser, cover for Macs and Android phones on one license, and bundled extras like a VPN or a password manager. Our free antivirus guide helps you decide if those extras matter to you, and the best antivirus roundup covers the wider field.
Neither Bitdefender's nor Norton's consumer products pay us. We have no reason to prefer one, and we did not test them ourselves: the protection figures below are the labs', and the features are what each company publishes.

When Norton is the better fit
- You want backup in the same box. Norton 360 Deluxe includes cloud backup for a Windows PC, according to Norton. Bitdefender does not lead with backup.
- You want identity theft protection from the same company. The "with LifeLock" plans put credit and identity monitoring next to the antivirus. Freeze your credit first, though: it is free and stops more new-account fraud than monitoring does. See how to freeze your credit.
- You like one brand for everything. Norton's bundles lean toward all-in-one.
When Bitdefender is the better fit
- You want the cheapest multi-platform plan. Bitdefender's entry plan covers Windows, macOS, iOS and Android on up to three devices, according to its plan page.
- You have a lot of devices. Its Family versions cover five people and up to 25 devices.
- You care most about a light footprint. Both scored 6 out of 6 for performance in the latest AV-TEST round, but Bitdefender's lower tiers carry fewer bundled extras to run.
The renewal trap, and how to avoid it
Both companies advertise a first-year price. Bitdefender's terms say the price offered is valid for the first year and that the subscription then renews automatically; Norton's page lists savings "compared to the renewal price". In both cases the second year costs more.
Three habits that save money
Bitdefender's terms also describe a 30-day refund window after purchase or renewal. If a renewal catches you out, ask for it promptly.
What neither one fixes
A security suite will not stop you from typing a password into a convincing fake login page, approving a sign-in prompt you did not start, or sending money to a scammer who phoned you. A password manager, two-factor authentication and the habits in our scams hub cover those. The five-minute self-check will show you where your real gaps are.
Common questions
Is Bitdefender better than Norton?
On protection they are tied: both scored 6 out of 6 for protection, performance and usability in AV-TEST's July and August 2026 test, and both won AV-Comparatives' Top-Rated award for 2025. The difference is in plans and extras.
Which is cheaper, Bitdefender or Norton?
Both advertise first-year prices that rise at renewal, and both change prices often. Compare the plan you would actually use on each company's own page on the day you buy, and check the renewal price.
Does Norton include LifeLock?
Only the Norton 360 with LifeLock plans. Norton 360 Deluxe includes dark web monitoring but not LifeLock identity theft protection, according to Norton's product page.
Do I need Bitdefender or Norton on a Mac?
Many Mac users do not. macOS includes XProtect, which Apple says blocks and removes known malware. A suite mainly adds web filtering and multi-device convenience.
