How to scan and protect your Android against malware with Google Play Protect and the latest security features

Protect your Android device from malware is an increasingly important priority, given the growing sophistication of attacks and the amount of personal data we store on our phones and tablets. There are multiple cyber threats that can affect users, from malicious applications to phishing campaigns, spyware, and ransomware. Given this scenario, Google Play Protect It is positioned as the native security solution for most Android devices, offering comprehensive and automated protection that doesn't require advanced knowledge to use, but does require a good understanding to take advantage of all its capabilities.

What is Google Play Protect and why is it key to your Android's security?

Google Play Protect is the security system integrated into Android Developed by Google to keep your devices safe from malware and potential threats. Designed as a multi-layered defense, it acts automatically, continuously scanning both apps downloaded from the Play Store and those from external sources. This way, it protects against the latest and most sophisticated threats, strengthening user privacy and ensuring a safer digital environment.

Its main functions include:

Automatic application analysis before, during and after installation, both from the Play Store and from external sources (APK).
Detecting harmful behaviors and sending alerts if an application is suspicious or dangerous.
Automatic deletion or blocking of applications that violate security policies or pose a risk to the user.
Resetting app permissions not to be used, to avoid information leaks or unnecessary access to personal data.
Protection against unwanted software and fraud, such as apps that hide relevant information or use sensitive permissions maliciously.

Google Play Protect updates automatically and continuously, leveraging machine learning and Google cloud databases, allowing it to adapt to new threats in real time and protect hundreds of millions of Android devices worldwide.

How does Google Play Protect work? A detailed explanation of its protection.

The main strength of Google Play Protect lies in its automatic and transparent analysis for the userOnce activated (on the vast majority of Android devices, it's enabled by default), it scans each app before it's installed on the device. The process consists of several stages:

Pre-scanning and continuous scanning of the Play Store: All apps on Google Play are analyzed before publication and periodically. This scan uses advanced detection techniques to identify malicious code, Trojans, ransomware, and any anomalous behavior.
Analysis during installation: When a user downloads or updates an app from the Play Store, Play Protect verifies the file again to ensure that no risks have been introduced in the latest versions.
Monitoring external apps (outside the Play Store): If you install apps via APK files from external sources (a process called sideloading), Play Protect can scan these files in real time before the app is installed.
Periodic analysis of the device: Every day, Google Play Protect reviews all apps installed on the device, checking whether any have changed their behavior, requested suspicious permissions, or become part of a blacklist of threats.
Notifications and automatic actions: When the system detects a threat, it can warn the user, disable the application, automatically uninstall it, or prevent installation in the first place. This minimizes exposure to malware even if the user is unaware of the danger.
Permission and privacy control: To protect your privacy, Play Protect can reset permissions for apps that haven't been used for a while and send alerts about apps that misuse access to personal information. This feature is especially applicable to recent versions of the Android operating system.

This entire process is performed without affecting the device's performance, as the most intensive analysis tasks are typically performed when the phone is connected to the charger and not actively in use.

How to check the status and settings of Google Play Protect on your device

To ensure Google Play Protect is working properly and to view your device's scan history, follow these steps:

Open the application Google Play Store on your Android mobile or tablet.
Click on the your profile icon in the upper right corner.
Choose Play Protect.
Within this section, you'll see information about the status of the last scan performed, as well as a list of recently reviewed apps.
From here you can activate or desactivate Play Protect (although it is recommended to always keep it active for security reasons).

If you want to force an immediate analysis, just press the "Analyze" button. You will also be able to access the advanced settings from Play Protect, where you can:

Enable the option to improve detection of harmful apps, allowing the system to automatically send samples of unknown apps to Google for in-depth examination.
Review or manage permissions of applications that are not used regularly.

On newer devices, you can even check if your device is certified for Play Protect within the Play Store settings (Settings > About).

How to scan APKs from external or unknown sources with Google Play Protect

In addition to protecting you from apps downloaded from the Play Store, Google Play Protect allows you to scan manually installed apps (APKs), which is essential if you frequently install apps outside the official store.

When you try to install an APK, Play Protect may ask for permission to scan it.
If you have the “Improve the detection of malicious apps"The system will automatically send relevant information about the new app to Google, enabling a more comprehensive analysis and updating threat databases in real time.
Scanning is performed locally, so even if there is no internet connection, Play Protect will apply known rules to stop malware from installing.
If any third-party apps are detected as harmful, Play Protect will notify you and can automatically remove them before they cause any harm.

This protection is especially important today, as installing apps outside of Google Play increases the risk of infecting your device with unreviewed malware.

Malware categories that Play Protect blocks on Android

Google Play Protect identifies a wide variety of threats, ranging from classic malware to new emerging variants. Some of the key categories it detects and prevents include:

Trojans: Apps that appear harmless but hide malicious functions, such as sending SMS messages without consent or stealing data.

Ransomware: Programs that block access to data or the device and demand a ransom for its release.
Rear doors: Codes that allow an attacker to take remote control of the device.
Phishing: Apps or codes that pretend to be legitimate in order to obtain sensitive data, such as passwords or banking information.
Spam and unwanted messages: Applications that send automatic and bulk messages to the user's contacts.
Hostile download apps: Applications that, while not malicious in themselves, download other potentially harmful apps.
More expensive: Apps that pose as legitimate or change their functionality after installation to hide their true purpose.
Unwanted Software (UwS): Apps that, while not actually malware, negatively affect the device or steal data such as phone numbers, email addresses, or information about installed apps.

Each time Google Play Protect detects one of these threats, it displays specific warnings. Depending on the type and risk level, it will either prevent installation or proceed to uninstall and block the app.
