Norton 360 ships a strong malware engine wrapped in a suite that has grown heavier every release. The renewal jump from the introductory year to the standard rate often more than doubles the price, the Android app footprint pushes well past 200 MB after first scan, and the home screen now leads with Genie, Scam Protection Pro and Dark Web Monitoring upsell cards before the actual scan results. The seven Norton 360 alternatives below cover the cases where Norton’s bundle is overkill: lighter free options, a leaner paid suite, brand-engine variety to escape the Symantec stack, and on-demand scanners that do not run in the background at all.
Why people leave Norton 360
- Renewal prices climb sharply after the first year. Subscriptions that started in the low double digits per year often renew above the price of the equivalent Bitdefender or ESET plan.
- The app suite has expanded into Scam Protection Pro, Genie AI, dark web monitoring, ad tracker blocker and a VPN, with constant upsell prompts that push paid tiers from inside the free flow.
- The Android install footprint and battery use sit above lighter peers. AV-Comparatives mobile reports have flagged Norton’s impact on app start time and battery in recent rounds.
- The Accessibility Service permission required for Safe Web and App Advisor reads on-screen content. Some users find that scope hard to justify for a single antivirus tool.
- The VPN is not available in every country, with India removed entirely after data-logging regulations changed. Users in those regions pay for a feature they cannot use.
- Buying paths overlap awkwardly between the Google Play subscription, the Norton website and partner bundles. Renewing on a different surface than the original purchase has caused duplicate-charge complaints in support forums.
- The mobile UI repackages the desktop suite’s marketing language. Casual users who only want a virus scanner spend several taps getting past suite cards.
If those points are biting, here are seven Norton 360 alternatives worth installing.
Which app should you choose?
-
Bitdefender Mobile Security if detection accuracy and low device impact matter most.
-
ESET Mobile Security if the phone is older or low-RAM and a lightweight engine is the priority.
-
Avast One if a generous free tier with VPN minutes covers the use case without a subscription.
-
AVG AntiVirus if Avast’s UI feels heavy but the same engine and free protection still appeal.
-
Kaspersky if the strongest free detection engine is the deciding factor and regional restrictions are not an issue.
-
Malwarebytes if on-demand cleanup of a suspect device is the actual job rather than always-on protection.
-
Sophos Intercept X for Mobile if a free, ad-free, no-account scanner with link checking and authenticator covers the need.
Stay on Norton 360 if the household already pays for Norton on a Windows PC and adding mobile devices to the existing seat count is cheaper than buying a separate mobile-only product.
1. Bitdefender Mobile Security — best overall replacement
Bitdefender Mobile Security is the closest like-for-like swap for Norton on detection. AV-TEST scoring on the Android engine has held at the top of the field for several years running, with full marks against zero-day samples and near-zero false positives. The app itself is lighter than Norton, with a smaller install footprint and a less crowded home screen.
The protection set covers real-time app scanning, web protection inside Chrome and other browsers, anti-theft, account privacy and a built-in VPN with a 200 MB daily cap on the standard plan. Norton 360 vs Bitdefender Mobile Security comes down to bundle versus focus. Norton stacks scam protection, dark web monitoring and ad tracker blocking. Bitdefender keeps the surface narrow and runs the core scanner more cleanly.
The trade-off is the cap on the bundled VPN. The 200 MB daily allowance is fine for occasional checks on public Wi-Fi but not enough for routine streaming. The Premium VPN add-on lifts that cap at extra cost, similar to how Norton tiers its VPN access.
Advantages:
- Top-tier AV-TEST detection scores
- Lower battery and CPU footprint than Norton
- Account Privacy checks for breach exposure
- Cleaner home screen with fewer upsell cards
Disadvantages:
- Bundled VPN capped at 200 MB per day
- Free tier on Android is more limited than Norton’s free side
- No dedicated parental control on the mobile plan
Pricing: Free tier with on-demand scanning. Paid plans start at a modest yearly subscription that covers multiple devices, with discounts on multi-year terms.
Bottom line: Pick Bitdefender Mobile Security when the goal is straight detection quality with a smaller suite and a lighter app.
2. ESET Mobile Security — best for older or low-RAM phones
ESET keeps a reputation for being the lightest engine on hardware that struggles. The Android app installs small, scans fast and uses noticeably less RAM and battery than the Norton or Avast suites. For phones running Android 10 or earlier on 3 GB or 4 GB of memory, that gap is the deciding factor.
The free tier covers on-demand scanning, real-time protection on installed apps and a basic anti-theft module. The paid Premium tier adds Anti-Phishing inside browsers, App Lock, scheduled scans and Security Audit. Norton 360 vs ESET Mobile Security is essentially a weight class question, with ESET sitting one notch lighter in every measurable category.
The trade-off is the spartan UI and the lack of a bundled VPN. Users coming from Norton expecting a single dashboard for VPN, scam blocking and antivirus will need a separate VPN app. ESET’s strength is doing one job well, not stacking adjacent features.
Advantages:
- Lowest measured RAM and battery use among major mobile suites
- Real-time protection on the free tier
- Clean UI with no upsell pop-ups during normal use
- Strong on older Android builds
Disadvantages:
- No bundled VPN at any tier
- Free tier lacks anti-phishing browser protection
- Smaller breach-monitoring story than Norton
Pricing: Free tier with limited features. Premium subscription is modest and renews at the same rate as the introductory term.
Bottom line: Pick ESET Mobile Security when the phone is older, RAM is tight and the user wants antivirus without a feature stack.
3. Avast One — best free tier with bundled VPN
Avast One is the rebrand of Avast Mobile Security and brings the broadest free tier in the category. The free version includes on-demand and real-time virus scanning, junk file cleanup, a privacy advisor and a daily VPN allowance, which is unusual at zero cost. Norton’s free side is much narrower, mostly limited to the basic scanner.
The paid Avast One Premium plan removes the VPN cap, adds dark web monitoring and unlocks data breach alerts. Norton 360 vs Avast One is a price-bracket comparison. Avast One Premium is generally cheaper at renewal than Norton 360 Standard for the same device count, and the free tier already covers a meaningful slice of what Norton charges for.
The trade-off is the size of the suite. Avast One mirrors Norton’s strategy of bundling adjacent features, so the app is heavier than Bitdefender or ESET. The data sharing history of Avast’s parent company also remains a consideration for privacy-sensitive users, although the company exited its Jumpshot data-broker arm several years ago.
Advantages:
- Generous free tier including a daily VPN allowance
- Real-time scanning on the free side
- Cheaper renewal than Norton at equivalent device counts
- Junk cleanup and privacy advisor included
Disadvantages:
- Larger app footprint than focused antivirus tools
- Privacy track record under the parent company is mixed
- Frequent upsell prompts inside the free flow
Pricing: Free with broad protection. Premium unlocks unlimited VPN and breach monitoring at a yearly subscription.
Bottom line: Pick Avast One when a free tier with a real VPN allowance and full real-time scanning is the deciding factor.
4. AVG AntiVirus — quieter sibling of Avast
AVG runs on the same engine as Avast but ships a calmer interface. Same-grade detection, same junk cleanup tools, less marketing surface in the app itself. For users who liked Avast’s protection profile but found the home screen busy, AVG is the same product with the volume turned down.
The free tier covers virus scanning, link checking through Web Shield, photo vault and an app permission audit. The paid AVG AntiVirus Pro adds App Lock, anti-theft camera trap, Wi-Fi Security and removal of in-app ads. Norton 360 vs AVG AntiVirus is a UI preference question wrapped around the same engine quality, with AVG holding the simpler layout.
The trade-off is feature parity with Avast One. Anything Avast does, AVG does, but the bundle is shaped slightly differently and AVG omits the bundled VPN even at the paid tier. A separate VPN is needed for the same end state Norton 360 offers.
Advantages:
- Same engine as Avast One with less interface noise
- Free tier covers scanning, Web Shield and a photo vault
- Lower CPU footprint than the bundled-suite tier
- Long-running brand with steady updates
Disadvantages:
- No bundled VPN at any AVG tier
- App Lock and Wi-Fi Security gated behind the paid plan
- Fewer breach-monitoring features than Norton
Pricing: Free with ads. AVG AntiVirus Pro yearly subscription removes ads and adds the paid features.
Bottom line: Pick AVG AntiVirus when Avast’s engine appeals but the interface needs to be quieter, and a separate VPN is acceptable.
5. Kaspersky — strongest free engine, with caveats
Kaspersky’s mobile engine routinely scores at the top of independent tests with very low false positives. The free Android tier includes real-time scanning, anti-phishing on web links and call filtering, with the paid Plus and Premium plans adding identity theft alerts, password manager features and a VPN. Compared to Norton’s free side, Kaspersky’s is materially more capable.
Norton 360 vs Kaspersky is a brand and engine question on the technical side and a regulatory question on the policy side. The technical side favours Kaspersky on raw detection. The regulatory side adds context: US federal use of Kaspersky is restricted, the company has been removed from several public sector procurement lists in Europe, and some users avoid the brand on national-origin grounds. None of that affects on-device detection but it does change the trust calculus.
The trade-off is exactly the regulatory profile. Users in regulated environments or who follow the federal advisory should pick a different engine. The technical detection itself remains class-leading.
Advantages:
- Top free-tier scanning and anti-phishing
- Low false-positive rate in independent tests
- Call filter and link checker on the free side
- Paid plans add password manager and VPN
Disadvantages:
- Restricted from US federal use and several public sector contracts
- Brand sensitivity for some users
- Frequent upsell of the Plus and Premium tiers
Pricing: Free tier with strong protection. Plus and Premium subscriptions add identity, VPN and password features.
Bottom line: Pick Kaspersky when raw detection at zero cost is the priority and the regulatory context does not apply.
6. Malwarebytes — best for cleaning a suspect device
Malwarebytes earned its reputation cleaning Windows machines that other tools missed. The Android version carries the same approach: deep on-demand scans, focused on adware, stalkerware and the kinds of threats that slip past general engines. For a phone that is acting strange after a sideload or a suspicious link, Malwarebytes is the targeted second-opinion tool.
The free tier covers on-demand scanning. The paid Premium tier adds real-time protection, web protection against phishing and a built-in ad blocker for Chrome and other browsers. Norton 360 vs Malwarebytes is a category contrast: Norton is a permanent watchman, Malwarebytes is a cleanup specialist that also offers a watchman tier.
The trade-off is the narrower feature set. Malwarebytes does not bundle a VPN, breach monitoring or scam call filtering. Users who want the one-app answer that Norton sells will find Malwarebytes too focused.
Advantages:
- Strong at adware and stalkerware specifically
- Free on-demand scan is genuinely useful
- Premium adds real-time protection and ad blocker
- Long-running independent brand
Disadvantages:
- Free tier has no real-time protection
- No bundled VPN, breach or call-filter features
- Smaller test-lab presence than Bitdefender or Norton
Pricing: Free on-demand scanning. Premium subscription unlocks real-time and web protection.
Bottom line: Pick Malwarebytes when the job is checking and cleaning a suspect device, or stacking a second-opinion tool alongside a primary engine.
7. Sophos Intercept X for Mobile — best free no-account option
Sophos Intercept X for Mobile is the free pick when paid plans, accounts and ads are all off the table. The app comes from Sophos, an enterprise security vendor, and is fully free for personal use with no in-app purchases or ads. Real-time app scanning, web filtering against phishing, a Wi-Fi network reputation check and a built-in authenticator are all included.
The authenticator alone is unusual at zero cost and covers the same role as Google Authenticator, which is useful for users consolidating tools. Norton 360 vs Sophos Intercept X for Mobile is a paid-bundle versus free-tool contrast. Norton offers more surface, but Sophos delivers core mobile protection with no payment, no upsell stream and no telemetry tied to a personal identity.
The trade-off is the lack of advanced features. There is no VPN, no dark web monitoring and no scam call filter. The interface is also clearly enterprise-derived, with terminology that occasionally lands closer to a corporate device than a personal one.
Advantages:
- Fully free with no ads or upsells
- Real-time scanning, Web Filtering and Wi-Fi check
- Built-in authenticator for two-factor codes
- Backed by an enterprise security vendor
Disadvantages:
- No VPN, dark web or scam call features
- Interface is enterprise-shaped
- Lower brand recognition outside business IT
Pricing: Free.
Bottom line: Pick Sophos Intercept X for Mobile when the user wants real protection at zero cost, with no account, no ads and no upsell.
How to choose
Pick Bitdefender Mobile Security if detection accuracy and a lighter app are the deciding factors. The yearly cost is lower than Norton at renewal and the home screen does not stack upsell cards.
Pick ESET Mobile Security if the phone is older or short on RAM. The engine is the lightest in this list and battery impact is the lowest in independent measurements.
Pick Avast One if a generous free tier with a daily VPN allowance covers the use case. The Premium tier is also priced under Norton at equivalent device counts.
Pick AVG AntiVirus if the Avast engine appeals but the Avast One interface feels busy. The product is the same underneath, with a calmer surface.
Pick Kaspersky if raw detection at zero cost matters most and the regulatory context does not apply. The free tier is the strongest in the category for engine quality.
Pick Malwarebytes when the job is one-time cleanup of a suspect device or when stacking a second-opinion tool alongside a primary scanner.
Pick Sophos Intercept X for Mobile when paid plans, ads and accounts are off the table and a free, real-time scanner is enough.
Stay on Norton 360 when the household already runs Norton on a Windows PC and adding mobile devices to the existing seat count is cheaper than buying a separate mobile-only subscription.
FAQ
Is Bitdefender better than Norton 360 on Android? On detection accuracy and battery impact, Bitdefender Mobile Security has scored higher than Norton 360 in recent AV-TEST and AV-Comparatives mobile rounds. Norton wins on bundle breadth with scam protection, dark web monitoring and a more generous VPN, but the core scan quality favours Bitdefender.
What is the best free Norton 360 alternative? For full real-time protection on the free tier, Avast One offers the broadest coverage, including a daily VPN allowance. Sophos Intercept X for Mobile is free with no ads and includes web filtering and an authenticator. Kaspersky has the strongest free engine on raw detection.
Do Android phones really need antivirus? Modern Android phones with Google Play Protect already block most known malicious apps from the Play Store. Antivirus apps add value by catching threats from sideloaded APKs, phishing links, malicious PDFs and stalkerware, and by adding scam-call filtering and breach monitoring that Play Protect does not cover.
What is the cheapest Norton 360 alternative? Sophos Intercept X for Mobile is fully free for personal use. ESET Mobile Security and Bitdefender Mobile Security are usually cheaper than Norton 360 at renewal for the same device count.
Can I import settings from Norton 360 to another antivirus app? Mobile antivirus settings do not export between vendors. Each app needs to be configured separately, which usually takes only a few minutes. Subscription cancellation should happen through the original purchase channel, typically Google Play subscriptions or the Norton website.
Is Malwarebytes enough on its own? The free tier is on-demand only, so it is not enough as the sole protection. The paid Premium tier adds real-time scanning and web protection and is a credible standalone choice, especially for users who already trust the brand from desktop use.
