Do I Really Need Antivirus for an Android Phone?

If you’ve ever found yourself wondering “Do I need antivirus for Android?” It’s probably because Android runs on open-source code, making devices more customizable but less secure against viruses and other threats. 

Security threats and viruses for mobile devices are constantly evolving, but is it really necessary to install a third-party phone antivirus software on your mobile device? Android devices are more vulnerable to malware than other mobile devices — including Apple devices — so it could be worth considering.

In our article below, we discuss Android’s built-in safety features and why you should consider downloading Android antivirus software.

Can Android Phones Get Viruses?

Android phones don’t get traditional viruses that replicate and spread like on a computer, but they are still vulnerable to other types of malware. Threats like spyware, ransomware and trojans can secretly steal data, track activity or even take control of a device. 

One example is Triout, a spyware that hides in apps and records user activity. Malicious software can also be used for doxxing, ransom demands or data theft. Additionally, rooting your device or sideloading (manually installing) apps from unverified sources can weaken Android’s built-in security, making it easier for malware to infiltrate.

Android Safety Features

While Android devices are often considered less secure than some other operating systems, they do include several built-in security features designed to protect against malware and cyberthreats.

Google Play Protect

Google Play Protect is Android’s most prominent built-in security tool. It continuously scans apps in the Google Play Store for potential malware, warns users about harmful apps before downloading and removes unsafe apps from devices. Play Protect also scans sideloaded apps for malicious behavior and alerts you to suspicious activity. 

Software and Security Updates

Android regularly releases security patches and software updates to address vulnerabilities and enhance device protection. But unlike Apple’s centralized updates, Android’s rollout depends on manufacturers and carriers, meaning some devices may not receive updates promptly. To maximize security, you should enable automatic updates and install them as soon as they become available.

Safe Browsing

Android devices feature built-in Safe Browsing protection, particularly when using Google Chrome. This feature warns users about potentially dangerous websites, phishing attempts and downloads containing malware. To stay protected, ensure your browser and device software are up-to-date, as outdated versions may lack the latest security patches.

App Permissions

Located under Settings > Apps & Notifications > Permissions Manager, app permissions allow you to control what data and features an app can access, such as the microphone, camera, location, contacts and storage. Google has strengthened these controls in recent Android versions, ensuring apps only access what’s necessary. You should review permissions regularly and revoke access for apps that don’t need certain privileges.

Default Security Settings

Android devices come with default security settings that restrict the installation of apps from unknown sources. If a user tries to install an app outside the Google Play Store, the device will display a warning and require manual permission adjustments. Because this feature helps prevent malware infections, you should only override it when installing trusted applications from reputable sources.

Additional Security Measures 

• Google Play System updates: Introduced with Android 10, these modular security updates allow Google to push critical fixes directly to devices, bypassing manufacturers.
• Encryption: Android devices encrypt user data by default, protecting information in case of theft or unauthorized access.
• Find My Device: This built-in feature helps remotely locate, lock or erase a lost or stolen Android phone.
• Biometric authentication: Fingerprint and facial recognition add an extra layer of protection against unauthorized access.

By enabling and maintaining these security features, Android users can significantly reduce their risk of malware infections and data breaches.

Where Does Android Malware Come From?

Android malware typically comes from unverified sources and malicious applications that exploit security vulnerabilities. Unlike iOS, Android allows users to install apps from outside the Google Play Store, which increases the risk of encountering harmful software. While Google Play Protect helps filter out malicious apps, cybercriminals still find ways to distribute malware through deceptive tactics. 

Some common sources of Android malware include:

• Sideloaded apps from third-party stores
• Malicious apps disguised as legitimate software
• Fake app updates and security alerts
• Phishing links in emails, texts or websites
• Infected advertisements (malvertising)
• Exploits targeting outdated software
• Compromised public Wi-Fi networks

To minimize risk, users should only download apps from trusted sources, keep their devices updated and avoid clicking suspicious links or pop-ups.

What Are the Signs of Android Malware?

Malware can cause various issues on an Android device, often interfering with performance, security and usability. Here are some common warning signs that your phone may be infected:

• Unusual battery drain: Malware runs in the background, consuming power even when you’re not actively using your phone. A sudden and significant drop in battery life could indicate malicious activity.
• Overheating: Some malware strains overwork your device’s CPU, causing it to heat up abnormally even during light use.
• Slow performance: If your phone suddenly becomes sluggish, lags when opening apps or takes longer than usual to respond, malware may be using system resources.
• Unexpected pop-up ads: If you’re seeing excessive pop-up ads outside of apps or even on your home screen, adware may have infiltrated your device.
• Increased data usage: Malicious apps can use your internet connection to send stolen data, run hidden processes or display ads, leading to a spike in data consumption.
• Apps opening or closing on their own: Some malware takes control of your device, launching or force-closing apps without user input.
• Unknown apps installed without permission: If you notice unfamiliar apps on your phone that you didn’t download, malware may be installing additional software in the background.
• Frequent crashes or freezes: Malware can interfere with system functions, causing apps or even the entire device to crash or freeze repeatedly.
• Unauthorized charges on your account: Certain types of malware, like premium SMS fraud apps, can sign you up for paid subscriptions or make unauthorized purchases.
• Disabled security settings: If you find that antivirus software, Google Play Protect or other security settings have been turned off without your consent, malware may be trying to bypass detection.

How to Prevent Android Malware

Preventing malware on your Android device requires a combination of cautious behavior and security best practices. By following these steps, you can significantly reduce the risk of infection:

• Download apps only from trusted sources: Stick to the Google Play Store, which has built-in security measures like Google Play Protect to scan for malicious apps. Avoid third-party app stores, as they often lack proper vetting processes.
• Enable Google Play Protect: This built-in security feature continuously scans apps for potential threats. Make sure it’s enabled by going to Settings > Security & Privacy > Google Play Protect and running a scan manually if needed.
• Keep your device and apps updated: Cybercriminals exploit vulnerabilities in outdated software. Always install the latest Android updates and app patches to stay protected against newly discovered threats.
• Be cautious of app permissions: Before installing an app, check what permissions it requests. If an app asks for access to features unrelated to its function (e.g., a flashlight app requesting microphone access), it could be suspicious. Review permissions regularly in Settings > Apps & Notifications > Permissions Manager.
• Avoid clicking suspicious links: Phishing scams often spread malware through fake links in emails, text messages and social media. Never click on unknown or shortened links, especially if they urge you to download something or enter personal information.

Use a reputable mobile security app: While Android has built-in security, antivirus apps from trusted providers can offer extra protection by detecting and blocking threats in real time.

When to Consider Installing Android Antivirus

The necessity of additional antivirus software on Android devices is a topic of ongoing debate. Android’s built-in security features, such as Google Play Protect, offer a baseline level of protection by scanning apps for malicious behavior. For many users who download apps exclusively from the Google Play Store and practice safe browsing habits, built-in safety measures may suffice.

However, many Reddit users note that there are scenarios where supplementary antivirus software may be beneficial:

• You sideload apps from third-party sources: Apps downloaded outside the Google Play Store pose a higher risk of malware infection.
• You frequently use public Wi-Fi: Unsecured networks can expose your device to cyberthreats like man-in-the-middle attacks.
• You handle sensitive data: If you use your phone for online banking, work-related files or personal health records, extra security can help prevent data breaches.
• You want real-time protection: Some antivirus apps offer additional features like anti-theft tools, phishing detection and enhanced malware scanning.

Here’s when you don’t need additional antivirus:

• You only download apps from the Google Play Store: Google Play Protect already scans for malicious apps, reducing the risk of infection.
• You don’t use public Wi-Fi very often: If you only connect to a handful of secure networks that you know and trust, the chances of Wi-Fi-based fraud or unauthorized access are much lower.

You don’t use your phone to handle sensitive data: Not everyone trusts their phone with important and sensitive data. If you prefer to handle that data on your PC or laptop, your personal information is not at risk on your phone.
