Antivirus on your smartphone: useful or unnecessary?

These days, our smartphone is almost more important than our wallet. We use it for banking, work, social media, photos, and storing personal information. But how secure is all of this? Is antivirus on your smartphone really necessary, or just an unnecessary extra?

Why smartphone security is becoming more important

More and more cybercriminals are targeting mobile devices. According to recent data, the number of malware attacks on smartphones increases each year. Android users are at greater risk, as the system allows more freedom to install third-party apps. iPhone users are better protected, but by no means invulnerable.

Examples of mobile malware
Mobile malware comes in many forms, including:

• Spyware that reads your messages or listens through your camera and microphone.
• Banking trojans like FluBot, Xenomorph or SharkBot that pretend to be legitimate apps and steal your banking details through fake overlays.
• Ransomware that encrypts files on your smartphone and demands a ransom.

One example: in 2023, the Xenomorph malware was spread through a fake version of the Google Chrome app. It could intercept login details from over 50 European banks.

How secure are iOS and Android on their own?

iOS (iPhones) is known for its strong security, thanks to:

• Strict app review processes in the App Store.
• Sandboxing, where each app runs in its own isolated environment.
• No access to system components for apps without explicit permission.

Android gives users more freedom, but with greater risk. Fortunately, Android includes built-in protection such as:

• Google Play Protect, which automatically scans apps for malware.
• Permission controls that let you decide what an app can access.

Still, these measures aren’t foolproof — especially if you install apps outside the Play Store or engage in risky behaviour.

What does mobile antivirus actually do?

Mobile antivirus works much like on a computer: it scans apps, files, and websites for suspicious activity. But it’s mainly the extra security features that make mobile protection worthwhile:

• Anti-theft features: remotely lock or wipe your device.
• Phishing protection: scan links in emails, texts and browsers using real-time alerts or extensions.
• Wi-Fi scanning: detect unsafe networks.
• VPN: browse more securely, especially on public Wi-Fi.
• Data breach checks: find out if your email or passwords have been leaked using dark web monitoring.

When is antivirus on your smartphone recommended?

Antivirus isn’t overkill in the following situations:

• You use Android and also install apps from outside the Play Store.
• You regularly connect to public Wi-Fi networks.
• You use your device for work, store sensitive information or do mobile banking.
• You’re vulnerable to phishing links via text, email or WhatsApp.
• You have children and want features like parental controls or screen time limits.

For Android users, app scanning is essential. For iOS users, the added features like identity protection, app locking and password management are especially valuable.

What if you only use official app stores?

Even though the App Store and Play Store have strict controls, malware has been known to slip through. Malicious apps can remain available temporarily before being discovered and removed. Also, app stores offer no protection against phishing, which often arrives via text, email or QR codes.

A solid security app fills these gaps — for instance, by blocking suspicious links or flagging fake websites before you click.

Honest advice from the experts at Antivirus.eu

At Antivirus.eu, we believe in honest and independent advice. Antivirus on your smartphone isn’t strictly necessary for everyone. But in many common scenarios, it’s a smart and sensible choice.

Our key recommendations:

• Using an iPhone and never installing anything strange? Then traditional antivirus might not be needed.
• Using Android? Then antivirus is strongly recommended — especially one that actively scans apps for malicious code.
• For both platforms, features like identity protection, password management, anti-theft and parental controls are essential for keeping you (and your family) safe.

And remember: your data might not seem “valuable” — until it’s stolen. That’s when you realise just how much you’ve lost.

Conclusion: useful or unnecessary?

If you’re a cautious iPhone user, antivirus may not be essential. But if you use Android, browse frequently, click unknown links, or use your phone for work or with children, then mobile security is a wise and necessary investment.
