Secure Your Android Device: Best Antivirus Apps
Updated On: May 8, 2025.
Android users face an expanding range of threats, from malicious apps and phishing links to data-harvesting spyware and ransomware campaigns.
While Google’s built-in Play Protect offers a decent start, it doesn’t cover all the bases. Advanced threats can slip through the cracks, especially with apps downloaded outside the Play Store or interactions happening via browsers, messaging apps, or public Wi-Fi. That’s why more users are turning to full-featured antivirus apps.
But forget the clunky, battery-draining software of years past—today’s best Android antivirus apps are fast, efficient, and tailored to mobile needs. In this guide, we’ll explore exactly why antivirus protection has become essential, how to choose the right app for your device, and what sets top performers like Avast, Norton, Bitdefender, ESET, and Avira apart from the crowd.

Why You Need Antivirus On Android
Malware-laced apps are more common than you think
While Google Play does its best to weed out malicious apps, bad actors still find their way in. Even official-looking apps can sometimes carry malware, especially those that request excessive permissions. Installing a trusted antivirus app adds a crucial extra layer of protection by scanning apps before and after installation and flagging anything suspicious.
Phishing attacks can happen anywhere
It’s not just emails anymore—phishing scams now come through texts, social media DMs, and even pop-up ads. These attacks can trick you into entering personal details or downloading something harmful. Antivirus apps help spot these threats before they do damage, often by scanning links in real time or blocking fake websites outright.
Public wifi isn’t always safe
Using wifi at cafes, airports, or hotels can leave you exposed to "man-in-the-middle" attacks or snooping. Many antivirus apps include built-in wifi scanning to warn you about insecure networks. Some also bundle in VPNs that encrypt your traffic, giving you an extra layer of security while you’re out and about.
Spyware and stalkerware are on the rise
Spyware isn’t just a thing of movies. In real life, stalkerware apps can be installed without your knowledge to monitor your activity, location, and messages. A good antivirus can detect and remove these hidden threats, helping you stay in control of your privacy.
Ransomware isn’t just a PC problem
Although more common on desktops, ransomware attacks on Android have been increasing—locking users out of their phones or files and demanding payment to get access back. Some antivirus apps can detect these threats early and stop them before they take hold.
What To Look For In An Android Antivirus App
- High malware detection rates: You want an app that’s consistently recognized by independent labs like AV-Test or AV-Comparatives. These services test how well antivirus apps detect real-world threats. Look for a detection rate of 99% or higher
- Low performance impact: Security shouldn’t slow your phone down. The best antivirus apps run efficiently in the background, use cloud-based scanning when possible, and don’t hog your battery or storage
- Real-time protection: Instead of just scanning manually, the app should offer always-on protection that checks every app, download, or site you interact with in real time
- Extra privacy features: Look for app locking, permissions managers, and identity monitoring. These tools help you keep control over what your apps are doing and protect sensitive info like your login credentials or photos
- Anti-theft capabilities: Features like remote lock, locate, wipe, or even trigger an alarm can help you act fast if your phone is lost or stolen. Some apps even snap a photo of the thief
- Wifi security tools: Not all networks are trustworthy. A good antivirus warns you about risky connections and, ideally, offers a VPN to secure your traffic on public wifi
- User-friendly design: You shouldn't need a cybersecurity degree to use your antivirus. A clean, intuitive interface makes it easier to stay protected and access the tools you need quickly
- Transparent upgrade options: Free versions are great, but if you're going to pay, make sure the app is upfront about what you’re getting. Avoid those with misleading upsells or unclear pricing
Top Antivirus Apps For Android
Avast Mobile Security
Avast continues to offer one of the most feature-rich antivirus apps for Android, especially impressive considering their free version is already quite powerful. They provide real-time malware protection, Wi-Fi security scanning, junk cleaning tools, and a photo vault to secure private images. Their App Insights tool gives you a breakdown of how much time you spend on each app and what permissions those apps are using, which is great for spotting privacy risks. Avast also offers an anti-theft suite that includes remote tracking, locking, and wiping if your phone is ever lost or stolen. If you upgrade to the paid version, you also get access to a built-in VPN and advanced anti-phishing tools. Their interface is clean, easy to navigate, and works well even on older phones.
Norton 360 For Mobile
Norton offers an impressively comprehensive package in their 360 app, making it a top-tier option for Android users who want more than just malware protection. They combine traditional antivirus features with a secure VPN, dark web monitoring, Wi-Fi threat detection, and a Safe Web browser extension to block malicious sites. Their App Advisor is particularly handy—it checks apps on the Google Play Store before you download them and warns you about potential risks. Norton’s privacy and identity protection tools go well beyond most competitors, helping you stay safe from both cybercriminals and shady apps. Though it’s on the pricier side, their all-in-one approach is well worth it for users who want strong, layered protection without juggling multiple apps.
Bitdefender Mobile Security
Bitdefender is known for its strong malware detection rates and low system impact, and their Android offering stays true to that reputation. The app uses cloud-based scanning to detect threats quickly without draining your battery or storage. They include a secure VPN (with daily limits on the free tier), account breach monitoring, and real-time web protection to block suspicious links. One of the highlights is the App Lock feature, which lets you secure any app—banking, messaging, etc.—with a PIN or fingerprint. Bitdefender also includes anti-theft functions like remote location, wipe, and lock, as well as a system that captures a photo of anyone trying to unlock your phone. Their minimalistic interface makes the experience smooth and simple.
ESET Mobile Security
ESET brings their strong desktop reputation to Android with a security app that’s both powerful and user-friendly. They focus on proactive security features—like real-time scanning, anti-phishing, and a detailed security audit that analyzes your phone’s settings for potential vulnerabilities. Their anti-theft tools are also standout: you can track your phone's location, trigger a loud siren, or send a custom message to whoever finds it. ESET also includes an App Lock tool to keep your most sensitive apps private and a Payment Protection feature that creates a secure environment when you’re doing mobile banking or online shopping. Their interface is slick and easy to use, making it a good fit for users who want hands-on control of their security.
Avira Security For Android
Avira takes a lighter, privacy-first approach to mobile security, but still packs plenty of value. Their free version comes with real-time antivirus scanning, identity protection (it checks if your emails have been leaked), and a built-in VPN with limited data. They also include a permissions manager to help you see which apps might be overreaching with access to your personal data. Avira’s anti-theft features let you locate, lock, or wipe your phone remotely. It also has system optimization tools to help free up storage and improve performance, which is a nice touch for users with older or slower devices. Their simple interface and strong privacy controls make Avira an excellent pick for budget-conscious users who still want solid protection.
