"Is it necessary to download an antivirus app on a phone? If yes, then can you suggest me the best ones?"
- From Reddit
In today's digital world, ensuring the safety and security of your devices is more important than ever. While most of us have antivirus software installed on our PCs, not everyone realizes the importance of having similar protection for our smartphones. Many users assume that smartphones are immune to viruses and malware, but this is a misconception.
While Apple devices are generally resistant to viruses, Android and Windows devices are vulnerable to various online threats. This is why it's crucial to install an antivirus app on your Android phone or tablet. In this article, we'll explore the best Android antivirus apps for 2025 to help you protect your device from malware, phishing, and other security risks.
Avast, a renowned cybersecurity brand from the Czech Republic, offers a well-rounded Android app catering to both casual and advanced users. It provides a free tier with essential protection and premium plans (e.g., Avast Premium Security) for enhanced features. Core Android-specific functionalities include real-time malware scanning, web protection against phishing links, Wi-Fi security checks, anti-theft tools (remote lock/locate/wipe), and app locking for sensitive applications like banking apps. The free version covers basic needs, while premiums add a firewall, limited VPN, and ad-blocking.
Pros:
* Robust free tier that meets most everyday users' security demands without cost.
* Responsive real-time monitoring that detects and blocks malicious files before installation.
* User-friendly interface optimized for Android's touchscreen, with intuitive navigation.
* Practical anti-theft tools that simplify lost device recovery.
Cons:

Avira, a German cybersecurity firm with long-standing industry experience, positions its Android app as an integrated solution for security and privacy. It focuses on strong malware defense paired with utility tools, offering free and premium plans (Avira Internet Security, Avira Prime). The free version includes on-demand malware scanning, app permission monitoring, and a password manager. Premium plans unlock real-time protection, a VPN (500MB monthly for Internet Security, unlimited for Prime), anti-theft features, and a privacy cleaner for browsing history and cache.
Pros:
* High malware detection rates in independent tests, especially for Android-specific threats like trojans and adware.
* Seamless password manager integration with Android's autofill system, enhancing usability.

Cons:

* Premium pricing is higher compared to similar competitors in the market.
* VPN has limited streaming support, failing to unblock most geo-restricted content (e.g., Netflix, Hulu).
Norton 360, from Gen Digital, brings enterprise-grade security to Android devices. It's designed for users seeking comprehensive, "set-it-and-forget-it" protection, with features extending beyond antivirus to data backup and family safety. Available in Standard, Deluxe, and Premium plans, all include real-time malware/ransomware protection, phishing detection, a password manager, and anti-theft tools (remote locate/lock/wipe/scream). Higher tiers add unlimited VPN, cloud backup (up to 100GB for Premium), and family safety controls (screen time limits, app blocking, content filtering).
Pros:
* Offers a 100% virus protection guarantee - refunds are provided if a threat is missed.
* Comprehensive feature suite covering security, privacy, and data backup in one app.
* Excellent family safety tools, ideal for parents monitoring children's device usage.
* Top-tier 24/7 customer support via chat and phone.
Cons:

AVG, now part of Gen Digital alongside Avast, leverages shared core technology to deliver straightforward Android security. It prioritizes simplicity and accessibility, with a free tier and premium plans (AVG Internet Security, AVG Ultimate). The free version includes real-time malware scanning, web protection, Wi-Fi security checks, and a Photo Vault for hiding sensitive images. Premiums add a VPN (limited data for Internet Security, unlimited for Ultimate), anti-theft tools, app locking, and a performance optimizer.
Pros:
* One of the most feature-rich free tiers on the market, with real-time protection rivaling some paid apps.
* Clean, easy-to-navigate interface, perfect for less tech-savvy users.
* Stable performance with minimal crashes in real-world use.
Cons:

* Premium VPN is slower than standalone alternatives like NordVPN; performance optimizer has limited effect on newer Android devices.
Bitdefender, a Romanian cybersecurity leader, consistently tops independent testing charts (e.g., AV-Test, AV-Comparatives) for malware detection. Its Android app focuses on top-tier protection, with free and premium plans (Bitdefender Antivirus Plus, Bitdefender Total Security). The free version offers on-demand scanning and basic real-time protection. Premiums add anti-phishing, unlimited VPN (Total Security), anti-theft tools, app locking, and Privacy Advisor (scans for excessive app permissions).

Pros:
* Industry-leading malware detection rates, including zero-day threats, via advanced heuristic technology.
* Lightweight performance on most Android devices, minimizing battery drain and lag.
* Autopilot feature that eliminates manual setting tweaks, ideal for hands-off users.
