Should You Worry About Getting a Cell Phone Virus?

You may be asking yourself, what if I have a cell phone virus and what is it anyway? You know you keep a lot of precious, valuable data on your phone, and when you hear in the news that mobile threats are on the rise, it’s easy to lose sight of the context behind the numbers and worry that you’ve gotten a dreaded mobile phone virus that’s going to steal your personal info and eat your children. Hopefully we can clarify things by addressing some of the questions that we hear most about so-called Android “viruses.”

Is there really such a thing as an Android virus?

Historically carried over from the old PC world, a “virus” is a program that replicates itself by attaching to another program. Hackers often used this method to spread their nefarious work, and virus became a popular term to refer to all types of malicious software (malware) on computers. In the case of smartphones, to date we have not seen malware that replicate itself like a PC virus can, and specifically on Android this does not exist, so technically there are no Android viruses. However, there are many other types of Android malware. Most people think of any malicious software as a virus, even though it is technically inaccurate.

So what is Android malware?

Malware, short for malicious software, is software designed to secretly control a device, steal private information or money from the device’s owner. Malware has been used to steal passwords and account numbers from mobile phones, put false charges on user accounts and even track a user’s location and activity without their knowledge. Learn about some of the most notable malware Lookout has blocked in Resources Top Threats.<?p>

How would I get malware on my phone?

Through Lookout’s research for the State of Mobile Security 2012, we’ve found that user behavior and geography greatly influence your risk of encountering malware. The safest bet is to stick with downloading well-known apps from well-known apps from reputable markets like Google Play in addition to having a security app. Fraudsters make it their job to disguise malware as innocent-looking mobile apps on app stores and websites. So if you’re thinking that it’s a good idea to download a just-published, supposedly free version of Angry Birds you found on a random Chinese app store, it’s probably not. Once installed, these apps may appear to work just as described, but they are can be busy with additional secret tasks. Some apps start out clean, but are given malicious capabilities after a seemingly routine software update.

And conscientious app downloading won’t always minimize your risk. Sneaky, drive-by-download sites can download a potentially malicious app file without any user intervention. Safe Browsing in Lookout Premium for Android will block web-based threats like that, but even so, you also shouldn’t install random downloads from your download manager that you didn’t expect to find there.

How can I protect myself and my mobile device?

It’s pretty simple to minimize the risk of encountering malware, and we’ve got 5 simple mobile security tips right here. The top two ways to protect yourself are to download a mobile security app like Lookout to catch those pesky “phone viruses” and to be judicious about what apps you download and were you download them from. Lookout will scour your phone or tablet for any existing malware, and also examine every new app you download to ensure it is safe. But even before you let Lookout scan your newly downloaded app, you should only download apps from sites you trust, check the ratings and read reviews to make sure they’re widely used and respected.

So, should you worry about getting a phone virus? Nope, because they technically don’t exist. (If they ever do crop up, Lookout will weed them out.) And should you worry about the more accurately termed malware? Well, with a little bit of awareness and Lookout on your phone and by your side, you can keep malware and other mobile threats at bay.


5 Best (REALLY FREE) iPad & iPhone Antivirus Apps in 2021

Scott Jackson
Updated on: November 1, 2021

Short on time? Here’s the best free iOS antivirus in 2021:

  • 🥇 Avira Mobile Security: Includes a privacy monitor, anti-theft protection, a limited VPN, a call blocker, and a performance optimizer. Get the free download here.

Here’s something most antivirus companies won’t tell you — virus scanning isn’t actually possible on iOS. This is because iPhones and iPads use an advanced security mechanism called “sandboxing”, which prevents apps from making changes to any other apps, files, or processes on your system. So basically viruses can’t infect iOS devices, because viruses can’t do anything on an iOS device.

So when most people say “antivirus for iOS”, they mean “internet security for iOS” —  covering a wide range of features that keep iPhones and iPads safe. Because iOS devices aren’t naturally protected against a wide range of other security threats, including:

  • Phishing links.
  • Unsafe public Wi-Fi networks.
  • Data-stealing apps.
  • Browser trackers.
  • Device theft.

I spent dozens of hours digging through scam apps, useless free apps, and fake security apps on the App Store, looking for products that could provide decent security coverage for all iOS users. I was able to find 5 free security apps for iOS that provide solid cybersecurity protection with no hidden fees or tricky trial periods.

However, there isn’t a single free security app for iOS that includes all of the features for complete iOS protection — if you understand that your data and your privacy are worth more than a few dollars per month, you should look at Norton’s fantastic iOS app.

Quick summary of the best free iOS antivirus apps for 2021:

How I Ranked the Best Free iOS Antivirus Apps:

No free security app is going to provide the kind of protection that I consider essential for an iOS device — but some of the apps on this list get pretty close. Here’s what I looked for in all of the apps that made it to my top 5 free apps for iOS:

  • 100% free. All of the apps I recommend offer long-term functionality at zero cost, not just free trials. However, all of these apps do offer premium versions that are much better — and most of them are pretty cheap (and many are available for a free trial).
  • Data privacy. There are a lot of free apps that exist solely to log and sell user data — there aren’t that many ways to make money with free products! However, all of the free apps on this list protect user data, and some of them even include additional tools that ensure your sensitive data doesn’t get compromised.
  • Ease of use. Apple already provides some great security features for iOS, but a lot of them are really hard to access. If you’ve ever tried to use the “Find my iPhone” web tool from Apple, you know it can be a real hassle. The tools and apps on this list provide increased security protections with convenient, well-designed user interfaces.
  • Efficiency. Many antivirus apps are buggy or slow down your iOS device. I analyzed my iPhone and iPad’s performance and battery life before and after installing each app, making sure that none of the apps slow down devices or drain batteries.

Top Brands That Didn’t Make the Cut:

  • Norton. I don’t want to mislead you: Norton’s iOS app is great, but it isn’t free. It offers Wi-Fi security protection, web protection, a VPN, and dark web monitoring. Still, if you’re looking for guaranteed protection, it’s the best iOS antivirus app there is.
  • Bitdefender.Bitdefender’s paid mobile app is decent, providing good web protection, data breach scanning, and a limited VPN. However, Bitdefender doesn’t offer a free version of its iOS app.
  • Avast/AVG. Avast is still one of the first security apps that pops up on the App Store, but it won’t be getting a recommendation from SafetyDetectives anytime soon. Avast owns AVG, and some disturbing reports came out about Avast/AVG selling user data to huge corporations. You can read more about it here.

1.🥇 Avira Free Mobile Security for iOS — Best Free Antivirus App for iOS in 2021

Avira Free Mobile Security for iOS provides more free features than any other free iOS app — and all of its features are useful, intuitive, and provide an additional layer of protection for iPhones and iPads.

One of the things I like most about Avira’s iOS app is the Privacy Manager feature, which is a downloadable iOS profile that prevents Siri from sharing your data with Apple — once installed, this profile prevents Siri from logging commands on Apple’s servers, which is great if you’re trying to minimize the amount of personal data that big businesses can collect from you.

Avira Mobile Security also offers a ton of additional security features, including:

  • VPN (100 MB daily limit).
  • Anti-theft protection.
  • Network scanner.
  • Device analyzer.
  • Photo storage manager.
  • Contacts backup.

I’m a big fan of Avira’s VPN, which provides fast encrypted internet access with a no-logs guarantee — so you know Avira isn’t profiting off of your browsing history. However, the VPN has a daily limit of 100 MB and it only lets you connect to one server location. Upgrading to Avira Phantom VPN Pro gets you unlimited data and a variety of global server locations.

Avira Free Mobile Security for iOS is a great free app, but most users will want to upgrade to Avira’s paid plans. You can subscribe to Avira Security Pro for iOS (adds anti-phishing, spam call blocking, and data breach monitoring) and Prime Mobile (adds a VPN with no limitations and a premium password manager). There’s also the Avira Prime package (currently off), which includes all of Avira’s features and coverage for up to 5 devices, including iOS, macOS, Windows, and Android devices.

Bottom Line:

Avira’s wide range of features make it the best free antivirus app for iPhones and iPads. Its Privacy Monitor feature will allow you to use Siri without having your interactions logged by Apple, and its anti-theft tools, call blocker, and VPN (limited to 100 MB/day) are all excellent. However, if you’re looking for web protections, a VPN with no limitations, and a secure password manager, you’ll need to upgrade to Avira Prime Mobile, which is available for a monthly subscription or as part of the larger Avira Prime antivirus package.

2.🥈 TotalAV Mobile Security — Good Range of Free Features for iOS

TotalAV Mobile Security provides most of its features to free users, including a secure web browser and an on-demand data breach scanner. TotalAV’s secure browser uses DuckDuckGo, a privacy-focused search engine, to ensure that users can access the web without being tracked or targeted by advertisers (DuckDuckGo is one of our top choices for the most secure web browser in 2021).

TotalAV also has a breach scanning feature that scans breach databases for compromised emails — I was relieved to see that my test Gmail account is still secure, but I wasn’t surprised to discover that my Hotmail account from 2005 has been a part of numerous data breaches in the last several years.

TotalAV also provides a few more free features, including:

  • Device locator.
  • Photo cleanup.
  • Battery manager.
  • System security.

TotalAV’s device locator is a basic anti-theft tool that lets you track your iPhone if it gets lost — it’s not as good as McAfee’s anti-theft tools, but it gets the job done. I also really like TotalAV’s photo cleanup feature that removes duplicate photos and screenshots from your device, and I appreciate that TotalAV’s free iOS app also includes system security that alerts you to iOS updates and prevents hackers from exploiting system vulnerabilities.

Upgrading to TotalAV Mobile Security Premium gets you anti-phishing protection and a VPN with no limitations — during my tests TotalAV’s VPN provided fast, reliable connections to a variety of servers worldwide, and it was even able to unblock geo-restricted streaming content on Netflix. TotalAV Mobile Security Premium is also included with TotalAV’s antivirus packages, which cover up to 6 devices across all operating systems.

Bottom Line:

TotalAV Mobile Security provides a lot of free features, including a secure browser and a data breach scanner. TotalAV’s other free features are pretty good too, including a device locator, duplicate photo cleanup, and a battery manager. Upgrading to TotalAV Mobile Security Premium gets you anti-phishing protection and unlimited VPN usage. There’s a 30-day money-back guarantee on all of TotalAV’s premium plans.

3.🥉 McAfee Mobile Security for iOS — Best for iPhone Theft Protection

McAfee Mobile Security for iOS is a simple free app that offers excellent anti-theft protections. My favorite feature is the remote anti-theft alarm — simply log into McAfee’s online dashboard to trigger a very loud alarm that gradually gets louder and louder. Unlike Apple’s rather quiet built-in iOS alarm, McAfee’s alarm literally sounds like a haunted house scream — it’s very hard to ignore!

McAfee’s anti-theft protection also offers remote location tracking and data wiping, as well as the option to display an automated message. iOS’s built-in “Find my iPhone” feature isn’t nearly as easy to use as McAfee’s, which is easily accessed from McAfee’s online dashboard.

McAfee also offers:

  • Wi-Fi scanner.
  • Media vault.
  • Contact backup.
  • System security scan.

McAfee’s Wi-Fi scanner is pretty good — it’s an on-demand scanner that will notify you if you’re using an unsafe Wi-Fi network. However, the media vault and contact backup features aren’t very useful because iOS already offers the ability to create a PIN-protected “Secret Album” for your media, as well as automatic iCloud backup for your contacts.

McAfee’s paid iOS security app offers a lot of advanced protections — McAfee Mobile Security Standard also includes real-time anti-phishing protection, and McAfee Mobile Security Plus adds an excellent mobile VPN (McAfee’s VPN did rank near the top of our best antivirus with a VPN for 2021).

You can get McAfee’s paid mobile plans with an individual subscription or bundled with McAfee’s 2-year Total Protection subscriptions, which cover up to 10 devices, including iOS, Mac, Android, and Windows devices. US users looking to protect more than 10 devices should check out McAfee’s Ultimate Coverage plan, which provides protection for an unlimited number of devices.

Bottom Line:

McAfee offers some useful security features, including an excellent remote anti-theft tool. Triggering McAfee’s alarm causes your iOS device to emit a very loud screaming sound, and its location tracking is much simpler than Apple’s “Find my iPhone” tool. If you’re looking for web protections like anti-phishing protection and a VPN, I recommend most users look into McAfee Mobile Security Standard or Plus — there’s a 30-day money-back guarantee on both paid plans.

4. Kaspersky Security Cloud Free for iOS — Best Free VPN and Security Breach Scan

Kaspersky Security Cloud is a minimal but decent free iOS security app with a secure VPN. The included VPN provides 300 MB of daily data (better than Avira), and it includes a no-logs policy, which means that even Kaspersky isn’t tracking your browsing history.

Using Kaspersky’s VPN, I was also able to stream high-quality video without slowdown, but unfortunately Kaspersky’s free version doesn’t include the option to choose your server from its global network, so you’re stuck with automatically connecting to a local server. For that option, you’ll need to upgrade.

Kaspersky’s breach scanning is pretty much identical to TotalAV’s breach scanner — simply enter your email address, and Kaspersky will check your email against a massive database of breached logins.

Kaspersky also includes a free password manager app — the app provides convenient auto-filling, password generating, and 256-bit AES encryption for user logins, but the free version is limited to only 15 passwords, which isn’t very good.

Just like all of these products, the free version of Kaspersky’s iOS app is a pretty limited version of its premium plan. Premium users get unlimited VPN usage with access to a global network of servers, plus anti-phishing protection and unlimited password storage across desktop and mobile devices. Plus, Kaspersky offers excellent parental controls — it’s one of my favorite parental control apps on the market.

Bottom Line:

Kaspersky’s free iOS app is essentially a VPN with dark web monitoring and a little bit of password management — it’s a decent sample of Kaspersky’s full offering, and 300 MB of daily VPN access is pretty good as long as you aren’t streaming video or gaming. Upgrading to premium protection gets you unlimited VPN browsing, unlimited password storage, anti-phishing, and parental controls — there’s a free 30-day trial of Kaspersky Security Cloud Premium and Family offered in the free app.

5. Lookout Personal for iOS — Good Breach Monitoring and Anti-Theft Tools

Lookout Personal for iOS provides an app update scanner, basic data breach monitoring, and missing device location tools for free users. Lookout’s System Advisor tool will give you notifications if your system is due for an update, which is only useful if you’re really good at ignoring iOS’s persistent update notifications.

However, Lookout’s Locate tools are pretty good — if you lose your device, you can go to the website and track your device on a map, issue a remote alarm, or even display a message on your screen to help good samaritans return your device to you. Lookout will even save the last location of your phone before its battery dies — which is a super helpful feature!

Lookout’s last free feature is an on-demand data breach scanner. Simply enter your email and Lookout will let you know if any of your logins have been compromised in a data breach.

Lookout’s free iOS protection is decent, but the paid app is much better.Lookout Premium includes anti-phishing protection, a Wi-Fi network scanner, and real-time data breach updates. Lookout also offers identity theft protections for Premium Plus users.

Bottom Line:

Lookout Personal for iOS provides decent lost phone protections, data breach scanning, and iOS update notifications. I especially like the remote alarm feature that can deter thieves and help detect lost iOS devices. However, I really think that users that enjoy Lookout’s iOS security tools should opt for the premium upgrade, which includes anti-phishing protection, Wi-Fi scanning, data breach reports, and identity theft tools.

Bonus: Traced — Free Web Browser & Network Protections for iOS Users

Traced is a free and lightweight iOS app that provides good web and network protections without compromising user privacy. Traced doesn’t gather any user usage data, which most security apps do — even top-quality apps like McAfee compile scan data to help keep their threat databases up-to-date.

During my tests, I was really impressed with Traced’s network scanner — it has live intrusion detection, which can help protect users from ARP spoofing attacks, man-in-the-middle attacks, and exploit attacks. I also like that Traced provides live browser protection, which can integrate with Safari on your iOS device.

Traced doesn’t provide important features like an app scanner or anti-theft tools, but it’s not a bad option for users that just want a Wi-Fi network monitor and additional browser security. Plus, Traced is completely free.

Bottom Line:

Traced is a minimal but effective network monitor and browsing protection app for iOS that doesn’t collect any user data. Traced’s Wi-Fi scanner provides live intrusion detection, and the browser protections integrate with Safari to add increased security against phishing and exploit attacks. Traced doesn’t provide an app scanner or anti-theft tools, but it can be a good addition to your existing antivirus app.

Antiviruses for iOS — Frequently Asked Questions

Do I really need an antivirus for my iPhone?

Apple is right when it says you don’t need an antivirus for your iOS device. And it’s also completely wrong. “Antivirus” is the wrong word to use because these apps aren’t really detecting viruses. But Apple’s built-in security measures can’t protect us from our own browsing habits. Phishing is a huge problem, theft is a huge problem, and browsing on unsecured networks is a huge problem.

And anyone who’s ever tried to use Apple’s clunky “Find My iPhone” features knows that you need a faster, louder, and more comprehensive option to find a lost device and deter thieves.

There’s really no reason not to install an antivirus app like Avira, TotalAV or McAfee on your  iPhone. Not only are our iPhones valuable assets, they also contain some of our most sensitive personal information.

Will iPhone antivirus apps work on my iPad?

In most cases, yes. iOS antivirus apps, like Avira, will work for most iOS devices, including iPads. But still, you should check with each product to make sure that the app offers the protection you want. There may be certain features that will only work on iPhones.

What kind of antivirus features do I need to stay protected?

Again, “antivirus” is a weird word for iOS security apps. While the threat of a traditional virus is low, there are all sorts of other threats that can compromise your cybersecurity.

Norton 360 offers the best range of security features, including phishing protection, data breach alerts, anti-theft tools, spam text and call protection, and more. Norton 360 isn’t free, but downloading a premium iOS security app is the only way to get all of the security features you need for your iOS device.

Users that are looking for a free security app should look into Avira’s free app for iOS. It has a good variety of features, but because of its limited VPN and lack of anti-phishing protections, I recommend most users upgrade to Avira Prime Mobile.


Virus Removal for Android

next →← prev

A virus is a term which is used to define a group of malicious program that attack and harms phones, tablets, and personal computers. Some cool types of malicious display invasive ads or redirect to another suspicious site. There are several threats such as info stealers, Trojans, and DNS hijackers take over the device completely and gain the root access. The virus downloads other malware and blocks its removal also. However, the biggest problem is that the official app store is still exploited by hackers; they hide the fraudulent apps inside them and infect users. But the question arises here is how to remove adware and viruses from the Android device.

In many cases, the removal of the Android virus is simpler as cleaning device's cache on any installed browsers such as Google Chrome. Another more radical option is performing a full device reset, which can, sadly, delete all your private files such as videos, music, photos, and other data available in the Android phone or tablet.

There are also several other easier methods to remove adware from Android; one of them is security software. However, some malware effects at the root of the device, and they are difficult to remove and terminate. But most of the wide threats can be removed using anti-malware tools.

  2. Avoid clone apps as they are 99% chances that your device will be affected by it.

The best Android antivirus apps in 2021

If you're an Android user, you need one of the best Android antivirus apps to protect your phone or tablet from corrupted apps and other kinds of malware.

Your choices are far from limited. The best Android antivirus apps offer not only top-notch malware detection and prevention, but a range of privacy and anti-theft features. Most have a free tier and some are entirely free.

The best Android antivirus apps will back up your contacts and other data, track your phone or tablet via GPS, snap a picture of a phone thief with the device's camera and even use your Wear OS smartwatch to locate your phone.

We've rounded up the biggest names in mobile antivirus protection — Avast, Bitdefender, Kaspersky, Lookout, McAfee, Norton and Google itself — and rated their Android apps based on setup, interface, usability, extra features and, of course, their anti-malware chops.

To gauge security protection, we used data from AV-Test, an independent German lab that rates most major security apps on their ability to detect malware and other threats. We also used the Geekbench 4 app to measure the impact these apps have on overall Android performance.

What are the best Android antivirus apps?

The best Android antivirus app, based on our tests, is Bitdefender Mobile Security ($15 per year), which offers nearly flawless malware protection and a wide range of features. 

Norton Mobile Security (starting at $15 per year) has even better protection. Unfortunately, Norton has killed the free tier of Norton Mobile Security and its anti-theft features, so we can't recommend it as highly as we used to.

Avast Mobile Security and McAfee Mobile Security offer a lot of features for free and do fairly well in malware-detection tests. But Avast's anti-theft and call-blocking tools didn't work well, and both apps show lot of ads — unless you pay them not to.

The free version of Kaspersky Mobile Antivirus has no ads, and its call-blocking and anti-theft features work well. Its malware protection is very good, but it lacks a Wi-Fi network-security scanner. 

Lookout Security & Antivirus was one of the first mobile antivirus apps and has a compelling identity-protection option. Yet there's little third-party lab-test data on Lookout's antivirus efficiency, so we don't really know how well it protects against malware.   

The last app, Google Play Protect, is installed on every Android phone that runs Google Play. Sadly, it's terrible at protecting against malware. Use something else.

The best Android antivirus apps offer not only top-notch malware detection and prevention, but also a range of privacy and anti-theft features. They can track your phone or tablet via GPS, snap a picture of a phone thief with the device's camera, and even use your Android Wear smartwatch to locate your phone.

The best Android antivirus app you can get

1. Bitdefender Mobile Security

Best paid option


Price per year: $15; free alternative is separate app

Minimum Android support: 5.0 Lollipop

Ads: No

App lock: Yes

Anti-theft: Yes

Reasons to buy

+Top malware protection+Affordable premium version+Many useful features+Small system impact

Reasons to avoid

-Expensive unlimited VPN option

Bitdefender's Android security app has nearly flawless malware protection, a very light performance impact, Android Wear watch integration, a VPN client and a malicious-website blocker that works with most Android browsers. 

It also has robust privacy-protection tools, including an app lock, a Wi-Fi scanner, anti-theft features and data-breach notifications. A newly added feature, Scam Alert, flags possibly malicious links in SMS text messages, messaging apps and screen notifications.

Bitdefender Mobile Security offers a 14-day trial period, but this is not a freemium app. The separate Bitdefender Antivirus Free for Android app (which is indeed totally free) only scans for malware. 

The built-in VPN client gives you only 200MB of free data per data — just enough to check your email while traveling. If you want more data, you'll have to pay $7 monthly or $50 yearly.

But at $15 per year, Bitdefender Mobile Security is well worth the expense. It's our choice for the best Android antivirus app.

2. Norton Mobile Security


Price per year: $15, $50 or $105; no more free version

Minimum Android support: 8.0 Oreo

Ads: No

App lock: No

Anti-theft: No

Reasons to buy

+Flawless malware detection+App Advisor beats the competition+Intuitive design

Reasons to avoid

-No more anti-theft functions-No more free tier

Norton Mobile Security, aka Norton 360, offers the best malware protection of any of the Android antivirus apps we tested. Unfortunately, it no longer has anti-theft functions, nor its contacts backups and Link Guard malicious-link blocker. 

Norton also killed Norton Mobile Security's free tier, which was the best among all the Android antivirus apps we'd recently tested. That's been replaced with a security-only app for one device that costs $15 a year.

For $50 a year, a medium-priced tier called Norton 360 for Mobile adds unlimited VPN service and "dark web" monitoring of your personal information. The most expensive plan, Norton 360 Deluxe, $105 per year, is actually part of Norton's antivirus lineup and lets you protect up to five Android, Windows, Mac or iOS devices. 

All of these subscriptions can be paid for right through the Norton app, which has a 14-day free trial period.

Norton's killer feature is the unique App Advisor, which checks apps on your device for heavy data usage and unusual behavior. It also checks apps in the Google Play store for security and privacy risks even before you install them.

3. Avast Mobile Security


Price per year: Free; $20, $40 premium versions

Minimum Android support: 6.0 Marshmallow

Ads: Free version

App lock: Premium only

Anti-theft: Partly premium

Reasons to buy

+Inexpensive premium version+Lots of features for free

Reasons to avoid

-Unreliable anti-theft features-Too many ads in free version

Avast Mobile Security & Antivirus is one of the most full-featured of the best Android antivirus apps, offering everything from a privacy adviser to a system optimizer to a customizable blacklist. 

But while Avast's malware protection is good, it's far from perfect. Some of Avast's anti-theft functions didn't work for us, and its call-blocking feature didn't work at all. (It's since been removed.) And the free version's ads and constant nags to upgrade are annoying and intrusive.

Those ads go away if you pay for either of Avast Mobile Security's paid tiers, Premium ($2 monthly or $20 yearly) or Ultimate ($7 monthly or $40 yearly). Users of either paid plan also get additional anti-theft features, an app locker and tech support.

The built-in client for Avast's SecureLine VPN is just a tease, and the only way to use it is to pay for an Ultimate tier. Since the stand-alone price for SecureLine is $60 per year, paying an extra $20 on top of the premium Android antivirus tier for unlimited VPN data is not a bad deal.

4. Kaspersky Mobile Antivirus


Price per year: Free; $20 premium version

Minimum Android support: 5.0 Lollipop

Ads: No

App lock: Premium only

Anti-theft: Yes

Reasons to buy

+Strong malware protection+Call blocking works+No ads in free version

Reasons to avoid

-Limited features overall-Free version won't auto-scan new apps

Kaspersky Mobile Antivirus, also known as Kaspersky Internet Security for Android, offers nearly-perfect malware protection, a small system impact and a call blocker that actually works. 

There are no ads in the free version, and not much nagging to upgrade to the paid plan. Free users get call filtering, Android Wear support and a strong set of anti-theft functions, but you have to scan each new app manually. 

Paying users get automatic scans of new apps, an app lock and blocking of known phishing websites. And that's about it. There's no Wi-Fi network scanner and none of the privacy tools that other Android antivirus apps now offer.

If you're just looking for malware protection, you can't really go wrong with Kaspersky Mobile Antivirus's free tier. But while the paid version is inexpensive, it feels stripped-down, and you can get more from Bitdefender's rival paid app for $5 less.

5. Lookout Security & Antivirus


Price per year: Free; $30, $100 premium versions

Minimum Android support: 5.0 Lollipop

Ads: No

App lock: No

Anti-theft: Partly premium

Reasons to buy

+Strong identity-protection option+Good user interface

Reasons to avoid

-Few free features-Not much malware-protection data-Heavy, slow scans

Lookout Mobile Security, now rebranded as Lookout Security and Antivirus or Lookout Personal, was one of the first Android antivirus apps, and for a long time the best. Its ease of use, clean interface and lack of ads explain its continued popularity. 

But Lookout's costs can rack up quickly. The free tier is bare-bones; it just scans for malware and locates lost phones. 

The premium tier charges $30 per year, even though some of its features — malicious website blocking, Wi-Fi network scanning — come free with other Android antivirus apps. An unlimited VPN and a data-breach notification service make the premium price worthwhile.

At $100 per year, the "premium plus" plan is actually a fairly inexpensive identity-protection service that offers many of the same benefits you'd get from LifeLock or IdentityForce. It might well be worth the expense. 

The trouble is that Lookout doesn't often submit its app to third-partly lab evaluations, so we don't really know how well Lookout protects against malware. Its active scans are also slow and heavy.

6. McAfee Mobile Security


Price per year: Free; $30 & $80 premium versions

Minimum Android support: 7.0 Nougat

Ads: Free version

App lock: Discontinued

Anti-theft: Discontinued

Reasons to buy

+Some decent free features+VPN if you're ready to pay a lot

Reasons to avoid

-Too many ads in free version-Pricey premium tiers-So-so malware protection

Like Avast, McAfee offers (or used to offer) a ton of useful features, but its free version is also full of ads and upsell suggestions. The malware protection is decent, if not fantastic. 

In the summer of 2021, McAfee Mobile Security phased out many of its most useful functions, including its App Lock, Guest Mode, Anti-Theft, Memory Booster and Storage Cleaner features. It's not really clear why this was done, other than to "adjust our product portfolio."

You'll get some good stuff with the free version of McAfee Mobile Security, such as a way to track each app's data usage and a Wi-Fi security scanner. 

You'll get even more with the "Standard" premium tier, including a URL screener, 24/7 tech support and no more ads. But it's a bit pricey at $30 per year considering that Bitdefender and Kaspersky give you the same features for less.

The top paid tier, "Plus," costs $80 per year and gives you the Standard features plus unlimited VPN access, but only for that single phone or tablet. You can get one of the best VPN services to cover all your devices for less.

7. Google Play Protect


Price per year: Free

Minimum Android support: 4.4 Kit Kat

Ads: No

App lock: Yes

Anti-theft: Yes

Reasons to buy

+Built right into Android+Small system impact+Good anti-theft tools

Reasons to avoid

-Awful malware protection-Few features

Google Play Protect comes built into every Android device that runs Google Play, and it would be great if it worked well. Unfortunately, Google Play Protect's dismal malware detection makes the strongest possible argument for using a third-party Android antivirus app. 

We did like that Google Play Protect's interface is minimal, there are no ads and the system impact is light. Some of Android's other built-in features, including Find My Device and Chrome Safe Browsing, mirror what third-party antivirus apps do on the side.

Google Play Protect's best feature is that Google can use it to remotely disable dangerous apps. This stays the case whether you're running third-party antivirus software or not. We recommend you not disable Google Play Protect.

But overall, Google Play Protect is awful at protecting you from malicious apps. For your own sake, please use something else.

Why you should use an Android antivirus app

Ideally, to keep your Android device safe, you should keep its software updated. Each new version of Android is more secure than the one before, and each monthly Android security update fixes newly found flaws.

But unless you've got a Google Pixel or Android One phone, you won't get those updates and upgrades right away. Most device makers need time to make sure changes to Android don't break their devices or software.

That lag time can be a couple of weeks, or it can be many months. Worse, some Android phone models stop getting Android OS upgrades after two years, and a few never get monthly security patches at all.

That's where the best Android antivirus apps come in. They stop attacks that try to get around Android's built-in defenses, especially those that Google has patched but which your device doesn't yet (or never will) have. They also stop new attacks that Google Play Protect won't catch, even on Pixel phones.

How to choose the best Android antivirus app for you

Android antivirus apps come in three pricing schemes: fully free, fully paid, and freemium.

Freemium apps let you choose between getting a limited set of features for free or paying to get a premium version that gives you all the possible features, similar to fully paid apps. Apps that offer a lot of features for free may also show you a lot of ads.

Such features might include anti-theft mechanisms, an "advisor" to help you examine and choose apps, a Wi-Fi network security scanners, or an app lock that requires a passcode to open specific apps. 

Both paid apps and premium tiers generally run between $15 and $30 per year. Some app makers try to limit on how many devices you can install their premium/paid versions. Some tack on a super-premium tier that gives you unlimited VPN service or an identity-protection-service, often at a pretty good price.

But the most important factor in deciding which Android antivirus app to use is malware protection. 

Norton and Bitdefender lead in this category, and Kaspersky is not far behind. Avast is good but not great, while the built-in Google Play Protect is terrible. We're not sure about Lookout and 360 Security because they haven't submitted their apps to recent lab tests.

How we tested the best Android antivirus apps

To gauge the security protection of the best Android antivirus apps, we used the latest bimonthly test results from AV-TEST, an independent lab in Germany that measures how well major Android security apps detect zero-day malware and other threats. 

Because some apps' scores are inconsistent from one test to the next, we also looked back at the previous two years of results.

We also used some results from AV-Comparatives, a lab in Austria that once a year tests nearly all the Android antivirus apps in Google Play, even those that don't cooperate with testing labs. But these tests are less detailed.

To measure the impact antivirus apps have on overall performance, we used the Geekbench 4 benchmarking app on a Google Pixel 3 phone running Android 9.0 Pie. For each app, we ran Geekbench several times with no AV app installed, then with one of the review apps installed, and finally during that app's full scan.

We also evaluated the number and usefulness of each app's features, took note of which features were reserved for paid users, and assessed the user interface and installation process.

Kaspersky antivirus products have been banned from U.S. government networks. Because the company is Russian, its software would create an unacceptable risk for persons and organizations involved in national security and critical infrastructure.

However, we think Kaspersky software is perfectly safe for home users. We've seen no evidence to convince us otherwise. Kaspersky researchers are well respected throughout the antivirus industry, and the company has publicly exposed Russian cyberespionage campaigns as well as American ones.
