What I found during my testing was that most were either fake, ineffective, filled with ads, or not actually free. I only found a few that I thought were good.

Most cybersecurity companies only want to make money. They don’t care if you’re actually protected, so they’ll limit their best features like real-time protection and malware removal — the features you actually need — until you pay for their premium antivirus app.
And if you have a lot of sensitive info on your Android device, you really should invest in a low-cost premium antivirus with mobile protection. But if you only need basic protection, there’s no reason why you should be paying money for something that you can get for free.
But you need to be careful! Some of the free apps on the Google Play Store are secretly malware in disguise, waiting for you to give permissions to all the important areas on your Android device just to steal your data. Every day there’s a new one of these that pops up on Google Play with fake ratings and fake descriptions. Don’t believe them. Only trust one of these free antivirus apps that has been personally tested and will guarantee your safety.
How I Rated the Best Free Antivirus Apps for Android:
Here’s what I look for in a free antivirus app for Android:
- 100% Free. Antivirus companies try to trick us with a free trial. We get comfortable using their service and then we forget that we need to cancel before the trial is over and we end up paying anyway. If you know you’re going to buy a mobile antivirus from a reputable company like Norton, a free trial is a great way to test out the service before you buy it. Otherwise, it’s just a marketing tactic to get you to download the app. All of my top 5 free antiviruses here are actually free. No free trials.
- Highly Secure. I only recommended Android apps from reputable cybersecurity brands, and I individually tested each one of them in line with our extensive testing procedures to guarantee that they can provide high quality security.
- Efficient. I stress-tested each of these apps and only recommended the ones that are simple, bug-free, and won’t slow down your device.
- Features. Even if some advanced features require a subscription, I’ve personally checked that all of the important features of these top 5 apps are available for free users.
Top Brands That Didn’t Make the Cut:
There are many free antivirus apps for Android available that didn’t make it into my top 5. Here are a few well-known brands you may have been expecting to see on this list:
- Norton Mobile Security. Norton’s Android app is one of the best low-cost premium options out there. Norton promotes several free features, but the Android app only works as a 30-day free trial. Still, if you know you’re not looking to compromise on your Android’s security, getting Norton for free for 30 days is a pretty great deal.
- Kaspersky Internet Security. Kaspersky provides a decent free antivirus solution for Android, but too many crucial features — such as real-time protection and anti-phishing — are only for premium users. That said, Kaspersky’s inexpensive premium app is really good.
- Avast Antivirus. Avast and AVG merged in 2016, and their Android apps are practically identical. AVG’s app made it to my number 5 spot, despite having a lot of ads. Although Avast’s app is very similar, I noticed a couple of bugs during testing, and it still comes with the same amount of annoying ads.
1. Bitdefender Antivirus Free — Best for Ease-of-Use
Many Android antivirus apps provide a lot of fancy features. But Bitdefender Antivirus Free only does one thing — it completely protects Android phones from malware — including viruses, spyware, and ransomware.
Using Bitdefender Antivirus Free couldn’t be simpler — just launch the app and tap the Scan button. I’ve had this app on my Android for months now, and I’ve only had to hit that button once because Bitdefender’s Autopilot feature automatically scans all of my new apps and downloads in real-time.
If you don’t need theft prevention, online account security, or safe browsing tools, then Bitdefender’s free app really is the best free Android antivirus out there.
And if those other things are important, you can always get Bitdefender’s premium Mobile Security for Android, which is one of the cheaper Android apps out there. You can also claim a free 30-day trial of Bitdefender’s Total Security plan (read our review here) and use the premium app for free during the trial.
Bitdefender Antivirus Free is an ad-free, no-nonsense free Android antivirus app. It’s the perfect choice if you want an antivirus app that sits quietly on your device without consuming battery life or resources while guaranteeing protection.
2. Avira Antivirus — Best for Privacy Protection
Avira Antivirus provides on-demand and real-time malware protection for Android devices.
One thing I really love about Avira’s Antivirus is the focus on privacy protection. Avira’s privacy-related features include:
- Permissions Manager. Keep track of how apps access your data.
- Identity Protection. Check if your email address has been stolen in a data breach.
- App Lock. Add additional security to your most private apps.
Other free features from Avira Antivirus include tools to protect against loss and theft, the ability to block unwanted calls and texts, and a VPN with up to 100 MB of data per day.
Paying users can access premium features such as safe web browsing and camera protection.
Avira’s trusted antivirus technology will keep your device free from viruses, spyware, and ransomware. It’s a great choice if you need your info to remain private and are concerned about identity theft.
3. ESET Mobile Security & Antivirus — Best for Safe Browsing
ESET Mobile Security & Antivirus provides a generous range of free features which lets us:
- Scan devices for viruses and other malware.
- Locate devices via GPS.
- Safely browse the web.
But my favorite feature from ESET is phishing protection.
Every day, fake phishing websites trick thousands of people into giving up their passwords, personal information, and credit card details. And since I use my phone to buy most things, I love that ESET’s anti-phishing feature integrates into the mobile browser to prevent me from visiting these phishing websites.
For network security, security auditing, and advanced anti-theft features, check out the powerful ESET premium Android app.
ESET Mobile Security & Antivirus offers effective, ad-free virus scanning and phishing protection. It’s a great choice if you use your mobile device to browse privacy-sensitive websites.
4. McAfee Mobile Security — Best for Theft Prevention
I love that McAfee Mobile Security offers so many great free features including real-time malware protection and device optimization to keep my phone running like new.
McAfee also offers some great free features to help prevent loss and theft, such as:
- Thief Cam which takes a photo from your front camera if someone’s trying to break into your phone.
- Remote wiping of your phone’s data if it’s lost or stolen.
- Locating your phone via GPS.
Premium features include a virtual private network (VPN) connection and an ad blocker. I think that these things are definitely worth the upgrade, though you can always find standalone VPN and ad blocker apps which will do just fine. The full-priced Mobile Security app is more expensive than the competition, but when you bundle your Android protection with one of McAfee’s Total Protection plans, the overall price becomes much cheaper.
McAfee Mobile Security brings McAfee’s powerful antivirus engine to Android, combining it with some helpful features to prevent loss and theft, which is a particularly important feature if you own a high-end Android device or store sensitive information on it.
5. AVG AntiVirus Free — Best for Extra Features
AVG AntiVirus Free is one of the more feature-rich free antivirus apps for Android I’ve been able to find.
It lets you:
- Scan your device for viruses and other malware.
- Scan Wi-Fi networks for security vulnerabilities.
- Test Wi-Fi speed.
- Clean up storage.
- Clear RAM to boost performance.
But be warned — AVG has a lot of ads, and they can take up nearly half the screen. This seriously affects this app’s useability. Premium users can remove the ads, and they get access to AVG’s VPN and some additional anti-theft tools. AVG has also gotten some bad press about selling free users’ data. So if you’re concerned about privacy, this probably isn’t the best app for you.
I don’t actually mind AVG’s free antivirus app that much, but McAfee has just as many free features, fewer ads, and they won’t sell your data.
AVG AntiVirus Free provides decent protection against malware, and it has a great range of device security and optimization tools. It’s not my first choice, but it’s OK if you don’t mind staring at a ton of ads (and having your data sold).
Frequently Asked Questions — Android Antiviruses
Are antivirus apps safe?
Android antivirus apps are not always safe, especially free ones.
Scanning for malware requires deep-level access to the most sensitive parts of your device. Malicious antivirus apps can easily compromise your privacy and security and steal your info.
I’ve thoroughly tested the 5 apps on my list. Each one comes from a brand with a strong reputation for creating excellent cybersecurity software. For example, my top free antivirus provider, Bitdefender, has over half a billion total users worldwide.
Why does android need an antivirus?
Your Android device is a valuable possession that contains highly sensitive data. And when compared to other platform providers like iOS, Android is not a secure operating system.
In addition to visiting malicious websites, various Android apps can easily access all areas of your device. Even many of the apps available on the Google Play Store have been known to contain malware.
Which Android devices will these apps work with?
All of the Android antivirus apps on this list will work with any Android smartphone or tablet running Android KitKat 4.4 (released in 2014) or above.
What kind of features can you get with an android antivirus app?
In addition to detecting and removing malware, a free Android antivirus application can:
- Keep your personal information private (I recommend Avira Antivirus for privacy protection).
- Protect you from malicious websites (ESET Mobile Security provides a free anti-phishing tool).
- Prevent loss or theft of your device (McAfee Mobile Security has some particularly effective anti-theft tools).
- Ensure you’re connected to a secure Wi-Fi network (McAfee can also do this).
Most antivirus apps also offer additional paid premium features, and for every free app out there, there are dozens more premium apps. If you know that your phone contains sensitive info that you don’t want getting out, it’s always better to go with a low-cost premium option like Norton.
