Best antivirus for Android
The confusion
Android has Google Play Protect running by default — a built-in scanner that checks apps on the device and vets new installs from the Play Store. Security researchers routinely find malware that made it through Play Protect and into the Play Store. Both of these things are simultaneously true.
The antivirus category on Android is murkier than on Windows. Some products in the Play Store that claim to be security tools are themselves adware or data-harvesting applications. The category that's supposed to solve the trust problem has a trust problem of its own.
It's not obvious whether adding a third-party antivirus on top of Play Protect meaningfully improves protection, or whether the primary risk on Android comes from somewhere Play Protect and antivirus both don't address.
What most people assume
Most people assume Google Play Protect catches everything in the Play Store before it reaches your device. Play Protect uses static analysis and behavioral signals, but its detection rate in independent testing (AV-TEST, AV-Comparatives) consistently trails dedicated antivirus apps. Malware has shipped through the Play Store in apps with millions of installs. Play Protect is a real first pass, not a complete filter.
Most people assume all Android security apps work like PC antivirus — scanning files, monitoring processes, blocking threats in real time. Android's permission model significantly limits what antivirus apps can do compared to their PC counterparts. They can scan installed apps, check URLs, and monitor app permissions — but deep behavioral monitoring of running processes, as exists on Windows, isn't available to third-party apps under normal Android security restrictions.
Most people assume their risk is the same whether they install apps exclusively from the Play Store or also sideload APKs from other sources. The threat profile is substantially different. Play Store installs go through Google's vetting process, imperfect as it is. Sideloaded APKs skip it entirely. The question of whether Android antivirus is worth installing depends heavily on which of these configurations describes the phone.
What's actually true
For a phone used exclusively with Play Store apps, the case for third-party antivirus is narrow. Play Protect handles the majority of Play Store threats, and a dedicated app adds limited protection beyond what's already present. The more compelling case is for phishing protection in the browser — some antivirus apps include real-time URL checking that Play Protect doesn't cover.
Where dedicated Android protection is clearly worth considering: phones that regularly sideload APKs from outside the Play Store, work phones storing sensitive business data, and phones used by people who click links in messages without verification. In those configurations, Bitdefender and ESET both publish Android products that score well in independent testing and stay within the platform's permission constraints responsibly.
Where you might be
If the phone only installs apps from the Play Store and you're not clicking links in unsolicited messages — Play Protect covers most realistic exposure. A third-party antivirus adds limited marginal protection in this configuration.

If the phone is used for work — email, VPN access, documents with client or company data — the consequences of a compromise are beyond personal. A product with real-time URL protection and app permission monitoring is a defensible addition.

See the mobile cleanup path →What no tool solves
Android's permission model prevents third-party antivirus apps from doing the deep process monitoring available on Windows. What they can do is scan installed apps, check URLs, and flag permission overreach. The protection ceiling on Android is lower than on PC regardless of which product is used.
A significant portion of mobile compromise happens through phishing — SMS links, messaging app links, email links — that lead to credential-harvesting pages. Antivirus with URL protection covers some of this; it doesn't cover every channel. Password hygiene and SMS phishing awareness are more direct defenses against this threat category.
Several security apps on the Play Store are themselves adware or aggressive data collectors. Installing an unvetted 'security' app from an unfamiliar vendor adds risk rather than reducing it. The products that appear regularly in independent AV testing — Bitdefender, ESET, Malwarebytes — are the safe starting points for this category.
