What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Android already includes an antivirus-like layer: Google Play Protect checks apps on compatible devices, including apps installed outside Google Play. It can warn about a harmful app, block an installation, disable an installed app, or remove it. That protection is useful but not infallible, and it does not replace Android security updates.
Third-party security apps add another scanner. Independent tests show that they can outperform Play Protect for particular threat sets, especially some stalkerware samples, while Play Protect performs competitively on broad malware tests with fewer false positives in one large test. The meaningful question is not whether “third-party” is automatically safer; it is which threat, test method, Android version and product build you are considering.

What Google Play Protect can detect
Play Protect is Google’s built-in app-protection service for compatible Android devices with Google Play services. Google documents it as scanning every app on a device regardless of where the app came from, rather than limiting checks to software downloaded through the Play Store. Its protections are aimed at harmful or potentially harmful applications, including malware distributed through sideloaded packages.
Google says its systems scan 200 billion Android apps every day. That is an operational-volume figure published by Google, not an independently measured detection rate. It shows the scale of the service, but it does not mean every malicious app will be identified.

Play Protect’s documented detection workflow includes several layers:
- Daily scanning: installed apps are checked automatically.
- User-started full scans: you can initiate a scan instead of waiting for the next scheduled check.
- Offline scanning: the service can help block known harmful apps when the device is offline.
- Real-time checks for non-Play installs: when an app is installed from an outside source, Play Protect can check it during installation on supported devices.
- Optional code-level analysis: if an app is unrecognized and suspicious, Play Protect may offer a deeper scan that sends app data to Google for analysis.
When an app matches Google’s harmful-app classifications, Play Protect can warn you, prevent installation, disable the app, or remove it. Those are documented response options, not a promise that every malicious application will trigger one of them. A new, modified or highly targeted threat can evade a detection system until its signals are available.
Play Protect is therefore best understood as continuous app screening built into the Android services many phones already use. It is not a complete inspection of every security weakness in the operating system, your accounts, your network or the physical device.

A third-party antivirus app supplies a separate scanning engine and its own threat database or cloud analysis. Running an additional scanner can create another opportunity to identify a suspicious application, but the result depends on the vendor’s detection logic, update speed, scan mode and the type of threat being tested.
Products can differ in what they inspect and how they classify risk. A full scan of installed applications is not equivalent to a real-time installation check, and a test aimed at ordinary malware does not measure stalkerware detection. Extra features may also vary by app version and subscription tier, so do not assume that every product offers the same monitoring or cleanup functions.
Independent evaluations show why a blanket “third-party is safer” claim is misleading. In one broad malware test, Play Protect was close to perfect and some third-party products reached the test’s maximum. In a separate stalkerware test using a different sample set and scan method, the gap was much wider. The test design matters as much as the headline percentage.

Broad malware results: a July–December 2025 endurance test
AV-TEST’s endurance test, reported in 2026, evaluated Android 12 products over testing conducted from July through December 2025. It used both a real-time malware set and a reference malware set. Six tested third-party products—Avast, AVG, Avira, Bitdefender, Kaspersky and Norton—detected 100% of the samples in both reported sets. Google Play Protect detected 99.6% of the real-time samples and 99.7% of the reference set.
Recommended Free Tools
| Product or group | Real-time sample detection | Reference-set detection | What the figures mean |
|---|---|---|---|
| Google Play Protect | 99.6% | 99.7% | Result from AV-TEST’s Android 12 endurance test, conducted July–December 2025 and reported in 2026 |
| Avast, AVG, Avira, Bitdefender, Kaspersky and Norton | 100% | 100% | Each reached 100% in the two malware sets used in that test; this is not a guarantee for every current threat |
The same evaluation checked false positives against nearly 11,000 harmless apps. Several products incorrectly flagged some harmless software, while a group that included Play Protect recorded no false positives in that set. A low false-positive count matters because an over-sensitive scanner can block a legitimate banking, accessibility or business app and make the warning harder to interpret.
These numbers are snapshots tied to the tested Android version, product builds, sample collections and laboratory procedure. They should not be merged into a universal ranking. A result from an Android 12 test does not establish identical behavior on every manufacturer’s Android release, and a 100% score on one sample set does not prove 100% coverage of newly emerging malware.

Stalkerware results: why the threat category changes the answer
Stalkerware is designed to monitor a person covertly, often by hiding its presence or abusing legitimate permissions. Its behavior and packaging can differ substantially from ordinary, widely distributed malware, so a general-malware score cannot be used as a stalkerware score.
AV-Comparatives and the Electronic Frontier Foundation tested 13 Android security products against 17 selected stalkerware cases in September 2025. Play Protect detected 53% of the cases. The tested third-party products ranged from 59% to 100%.
| Test detail | Google Play Protect | Tested third-party products |
|---|---|---|
| Selected stalkerware cases | 53% detected | Results ranged from 59% to 100% |
| Scan method | Evaluation by scanning installed apps | Products used full scans |
| Test date and scope | September 2025; 13 products and 17 selected cases | |
The different scan methods are important. A product given a full-scan workflow may inspect items that an installed-app check does not, so the percentages are not a like-for-like league table. The report demonstrates a threat-specific difference, not proof that every third-party scanner will find every stalkerware app or that Play Protect cannot find any.

If you suspect targeted monitoring, do not rely on one clean result. A hidden app can use a legitimate name, abuse accessibility or device-administrator privileges, or be installed after a scan. A full scan may still miss a sample, and removing an app can alert an abuser or destroy evidence. If personal safety is involved, use a trusted support service or law-enforcement guidance before making changes.

What the May 2026 AV-TEST scores do—and do not—say
AV-TEST’s May 2026 product evaluation tested 12 products using current versions and default settings. Cloud access and product updates were allowed. It scored three categories out of six rather than publishing a single detection percentage for each product.
| Play Protect category | Score | Interpretation |
|---|---|---|
| Protection | 5.5/6 | AV-TEST’s protection-category score in that dated evaluation |
| Performance | 6/6 | Impact measured by that test’s performance criteria |
| Usability | 5/6 | Usability result under the test’s criteria |
Many of the listed third-party products scored 6/6 in all three categories. Those category scores are not equivalent to a 100% malware-detection rate. Protection, performance and usability combine several measurements, so they should be read as a separate dated snapshot.
Is Play Protect enough for your phone?
For many people, Play Protect is a sensible baseline, especially when combined with current Android security updates and cautious installation habits. The answer changes with how you use the phone and which threat worries you most.
If you mainly install apps from Google Play
Keep Play Protect enabled and leave its automatic checks running. Google Play distribution reduces one common route for malicious packages, while Play Protect continues to scan installed apps. That combination may be sufficient for a typical user who does not need specialized monitoring features. “Sufficient” does not mean infallible: phishing, account theft, malicious web content and unpatched operating-system flaws are not solved simply by having an app scanner.

If you sideload APK files
Play Protect can still perform real-time checks for non-Play installations on compatible devices with Google Play services. Treat a warning as a stop signal rather than automatically overriding it. If Play Protect offers an optional code-level scan for an unrecognized app, understand that app data is sent to Google for analysis and decide whether to proceed. Obtain APKs only from a source you can verify, and remember that a clean installation check cannot prove the source will remain trustworthy after a later update.
If stalkerware is your primary concern
Use threat-specific evidence instead of broad malware marketing. The September 2025 test found Play Protect at 53% on its 17 selected cases and third-party results between 59% and 100%, with different scan methods. Select a product only when an independent test covers the stalkerware or spyware behavior you are concerned about, and do not treat one scan as conclusive.
If you manage work or family devices
Compare the product’s documented controls, alert handling and privacy terms with your management needs. A scanner that produces frequent false positives can create support work, while a scanner that misses a targeted threat can create a false sense of safety. Test the exact Android and app versions you deploy rather than relying on a score from another platform.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Android security updates are a separate layer
An antivirus app cannot substitute for operating-system and component patches. Android explains that system updates generally come from the device manufacturer or carrier, while Google Play Protect and Google Play services can warn about potentially harmful apps, including ones installed from outside Google Play.
Check your phone’s Android security-update date and install updates offered by the manufacturer or carrier. If a phone no longer receives security updates, adding another scanner may improve app-level visibility, but it does not repair vulnerabilities in the operating system, kernel, modem or vendor components.

A practical protection routine
- Leave Play Protect active. It is the built-in layer that checks apps from both Play and, on supported devices, outside sources.
- Run a user-started full scan after a warning or suspicious installation. Record the app name, source and warning instead of dismissing the alert without checking.
- Do not automatically override a non-Play warning. Re-check the APK source, requested permissions and developer identity. If the app is essential, look for an official distribution route rather than disabling protection.
- Install Android security updates when offered. These updates address system vulnerabilities that app scanners cannot fix.
- Add a third-party scanner only for a defined need. Choose evidence for your threat category, and verify the tested Android version, product version, scan mode and date.
- Review false positives before deleting a legitimate app. Confirm the warning with the developer or an independent test, particularly for banking, accessibility, enterprise and device-management software.
- Re-scan after major app or operating-system changes. Detection engines and threat signatures change, so an old clean result is not a permanent certificate.
How to compare a third-party app fairly
Use the following checklist when an app claims better protection than Android’s built-in layer:
| Question | Why it matters |
|---|---|
| What threat category was tested? | General malware, potentially harmful apps and stalkerware produce different results. |
| What Android and product versions were used? | Detection and permissions can change between releases and manufacturers. |
| Was the test real-time, installed-app or full-scan? | Scan coverage depends on the method; percentages from different methods are not directly comparable. |
| When was the test run? | Threats, signatures and app builds change quickly. |
| What was the false-positive rate? | Blocking harmless software can be as disruptive as missing a low-risk sample. |
| Were updates and cloud access allowed? | These conditions affect what a current product can identify. |
| Were performance and usability measured? | A scanner that drains the battery or produces confusing alerts may not be practical even with strong laboratory protection. |
Do not combine the 99.6% Play Protect result from the AV-TEST endurance test with the 53% stalkerware result from the AV-Comparatives/EFF test. They used different samples, dates and procedures. Combining them would create a number that no test actually measured.
Common mistakes and what to do instead
Assuming “built in” means perfect
Play Protect is integrated and continuously available, but the cited tests show that it misses some samples. Keep it enabled while recognizing that no scanner has universal coverage.
Free tools Windows power users keep installed
One-click scans. No signup required.
Assuming “paid” means safer
A price or subscription does not establish detection quality. Look for independent results that match your threat, and check the product’s current version and scan method.
Using a general-malware score to judge stalkerware protection
Stalkerware can behave differently and may require a full scan. Use a stalkerware-specific evaluation and treat its result as evidence about that test set only.
Ignoring the operating system’s patch level
An app scanner cannot close an unpatched Android vulnerability. Keep manufacturer or carrier updates current, or recognize the residual risk on devices that no longer receive them.
Installing several scanners without a reason
Multiple apps can duplicate scans, increase battery and notification load, and create conflicting warnings. Add a second layer only when its independently tested capability addresses a gap that matters to you.
Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Clear out junk files and repair common Windows errors3Scan for outdated or missing drivers - takes under a minuteBottom line
Google Play Protect provides meaningful, always-available app screening and checks apps regardless of their installation source on compatible devices. In AV-TEST’s July–December 2025 Android 12 endurance test, it detected 99.6% of real-time samples and 99.7% of the reference set, while six tested third-party products reached 100% in those sets. In the separate September 2025 stalkerware test, Play Protect detected 53% of 17 selected cases and third-party results ranged from 59% to 100%.
Use Play Protect and Android security updates as the foundation. Add a third-party app when a current, independent test shows a meaningful advantage for your specific threat—particularly if stalkerware or another specialized risk is your concern. Judge every percentage by its date, versions, samples, scan method and false positives, not by the label “built in” or “antivirus.”
