The best security setup for your phone starts with updates, a strong screen lock, unique passwords and a way to recover a lost device. An antivirus subscription can add useful protection on Android, but it cannot replace those basics. On an iPhone, an app advertised as “mobile security” does not perform the same system-wide malware scan as an Android antivirus.
Our shortlist separates malware protection, account security and lost-phone recovery so you can choose the tool for the problem you actually have. We checked official product documentation and download listings; these are feature-based recommendations, not claims that we personally ran malware samples or measured battery drain. Availability, subscription features and minimum operating-system requirements can vary by country and device.

For most people, start with the built-in protections, a password manager and account recovery. Add one Android security suite if you need its particular scanning or web-protection features. Installing several competing antivirus apps is not a useful substitute for choosing and configuring one.
Android and iPhone security are different
Android security apps can check installed apps and provide additional protection against malicious downloads or dangerous links, within the permissions Android allows. Google Play Protect already performs app checks on supported devices. An extra suite is most useful when its specific protections, alerts or management features fill a gap in your setup.
Apple uses app sandboxing and other platform controls to restrict what apps can access. That also prevents an ordinary third-party iPhone app from scanning every other app and the operating system like desktop antivirus. iPhone security subscriptions may offer web filtering, scam alerts, a VPN or identity-monitoring services instead. Read the iOS feature list separately from the Android one. Apple’s app-security overview explains the platform protections.
Google Play Protect: start with the Android baseline
Google Play Protect checks apps when you install them and periodically scans your device. It can warn about potentially harmful apps, disable them or remove them. Google also describes checks for apps installed from outside Google Play; this is not permission to assume any downloaded APK is safe.
Open Google Play, tap your profile picture, select Play Protect and review its status. In Play Protect settings, keep app scanning enabled. Devices without Google Play services may not have this feature, so check your manufacturer’s security and update arrangements rather than looking for an unofficial Play Protect download.
Choose it for: a no-extra-cost starting point. Its limit: an app scan cannot protect an account when you disclose its password or approve a fraudulent payment. Keep Android, your browser and apps updated as well.
Bitdefender Mobile Security: an additional Android suite
Bitdefender Mobile Security for Android combines malware scanning with web and scam-protection features. It is a candidate if you want a dedicated Android security subscription and will use those extra protections. Follow the official Google Play listing to avoid similarly named downloads.
Treat the trial as an opportunity to check compatibility, notifications and the permissions required for each feature on your own phone. Review the renewal price and any VPN allowance separately: a suite that includes a VPN does not necessarily include unlimited VPN traffic. We are not assigning a detection percentage or a battery-life ranking without a matching, identified test.
ESET Mobile Security: a basic free option with paid upgrades
The official ESET Mobile Security Antivirus listing offers a basic version and a Premium trial. This makes it worth considering if you want to try an Android antivirus before committing to a subscription. Premium features include protections and management tools beyond the basic scanner; compare the in-app feature table before relying on a particular function.
Do not confuse a time-limited Premium trial with permanent access to every feature. Check what remains enabled after the trial and whether a subscription is already included in an ESET plan you own. Permissions should match the features you choose to activate, not simply be accepted without reading the explanation.
Malwarebytes Mobile Security: malware and scam tools for Android
Malwarebytes for Android offers malware scanning alongside web, SMS and scam-related protections in its current mobile offering. Use the official Malwarebytes Google Play listing and check which functions your selected plan includes. A free download button alone does not establish that ongoing protection is free.
This is a reasonable option to evaluate when unwanted apps or suspicious links are your main concern. If you submit a message or screenshot to a scam-analysis feature, review what information you are sharing first. An assessment is an aid to your judgment, not proof that a transaction or sender is trustworthy. Avoid copying passwords, authentication codes or other unnecessary private information into a checking tool.
Bitwarden: protect accounts with unique passwords
Reused passwords create a different problem from malware. Bitwarden’s official apps help you generate and store unique passwords across Android, iPhone and computers. Its free personal tier includes core password management with unlimited passwords and devices; paid tiers add features such as integrated authenticator codes and emergency access.
Choose a strong master password, enable two-step login for the vault and keep recovery information somewhere you can reach without unlocking that same vault. Configure autofill through your phone’s settings and pay attention when a saved login does not match the site you opened. A password manager is not an antivirus, and storing a password does not make the destination legitimate.
2FAS Auth: add a second factor to supported accounts
2FAS Auth is a free, open-source authenticator for Android and iPhone. It generates time-based login codes for services that support this method. Use the download links on the Auth page: 2FAS Auth and the company’s separate password-manager product, 2FAS Pass, are different apps.
Set up two-factor authentication inside each account’s security settings, then keep that account’s recovery codes safely outside the phone. Before replacing or resetting a device, confirm you can transfer or recover your authenticator setup. A code app does not add two-factor authentication to an account until you enroll it, and codes can still be stolen by a convincing phishing page. Use a service’s passkey or security-key option when it suits your needs.
Find Hub and Find My: prepare before your phone goes missing
Android users should review Google Find Hub; iPhone users should turn on Apple Find My. These services help with locating and securing supported devices. Their available actions depend on the device, settings, account access and network conditions, so enable them before a loss occurs.
Check from another device that you can sign in to the relevant account. Keep account-recovery methods current and avoid making the missing phone your only way to receive a login code. Location information is not a guarantee that a phone can be recovered; do not confront a suspected thief based on an app’s map.
Why some familiar names are no longer recommendations here
The previous list treated several overlapping antivirus subscriptions as if every reader needed the same thing. This shortlist focuses on distinct needs instead. Omission does not mean that every other security product has disappeared or stopped working.
Kaspersky is not included as a general recommendation for U.S. readers. The U.S. Bureau of Industry and Security decision restricts covered Kaspersky transactions and the provision of antivirus-signature and codebase updates to U.S. customers from September 29, 2024. An installed copy is not equivalent to a supported, updating security product. This is a U.S.-specific restriction, not a claim that the software is unavailable everywhere.
Check these details before paying
- Device and country: open the official store listing on your phone and confirm compatibility and regional availability.
- Exact plan: distinguish the trial, permanent free features and paid protections. Compare the total renewal charge and device allowance.
- Permissions: read why web filtering, accessibility, notification access or a VPN connection is requested. Decline features you do not need.
- Overlapping subscriptions: check whether your existing household plan already covers your phone. Avoid paying twice for the same job.
- Recovery: save backups and recovery codes before a reset or device change. Security software cannot restore information that was never backed up.
Frequently asked questions
Do Android phones need antivirus?
Keep Play Protect enabled where available and install system and app updates. An additional Android suite may be useful for specific malware or web-protection features, but it does not make risky downloads safe or replace account security.
Can an iPhone antivirus app scan every app?
No. Ordinary iOS apps are restricted by the platform’s security model. iPhone security products generally provide features such as web protection, scam filtering or VPN services rather than a desktop-style scan of the whole system.
Which security tools are free?
Play Protect, the built-in lost-device services, Bitwarden’s core personal password manager and 2FAS Auth do not require a separate paid security subscription. ESET also offers a basic free version. Trials and premium features have different terms.
Will a VPN stop every scam?
No. A VPN protects a particular network connection; it does not establish that a website, message, investment or payment request is genuine. It also does not replace unique passwords, account verification or software updates.
What about VPNs? I’d suggest adding some VPN options like Atlas VPN which goes for free and is perfect for smartphones or Surfshark, a very cheap option if you want to work on PC’s as well.
