Q: What are the best free antivirus apps for Android?

My top recommendations are Norton Mobile Security (not 100% free, but it has a 60-day money-back guarantee) and TotalAV Mobile Security (good range of free features). Norton provides excellent antivirus protection along with a number of other useful features, including dark web monitoring (by far the best dark web monitoring of any antivirus app) and a fast VPN with unlimited browsing data, whereas TotalAV has excellent web protection, data breach scanning, and a secure browser. But there are many great free antivirus apps for Android, all of which either provide strong malware protection, web protection, or additional tools to keep your smartphone or tablet secure.

Question 1

Are free Android antivirus apps safe?

Accepted Answer

The ones on this list are all safe. But it’s important to know that 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 these apps, and they’re all legitimate, safe, and work exactly as promised. Each app comes from a brand with a strong reputation for creating excellent cybersecurity products. My top pick, Norton Mobile Security, is produced by a company with millions of users worldwide and decades of experience in the cybersecurity industry.

Question 2

Will an Android antivirus drain my battery?

Accepted Answer

The impact of an Android antivirus on battery life can vary widely based on the antivirus software itself and how it’s configured. Some antivirus apps such as Norton and Bitdefender are known for being energy-efficient and have a minimal impact on battery life, while others like TotalAV, as seen in earlier tests, can be more resource-intensive and may drain the battery quicker. Features like real-time scanning, cloud-based scanning, and frequent updates can contribute to higher battery usage.

It’s advisable to look for antivirus software that balances strong protection with energy efficiency. For instance, Norton has optimized its scanning processes to reduce battery consumption, and Bitdefender offers a Battery & Performance Saver feature.

Question 3

Do I need an antivirus on my Android phone?

Accepted Answer

The short answer is — yes! Your Android phone or tablet probably contains sensitive data like personal information, banking information, social media, personal pictures and files, etc. It’s also a relatively expensive item, thus attracting thieves.

And when compared to other platforms like iOS, Android isn’t all that secure of an operating system. Android OS is notable for having tons of indie developers, coders, and modders around the globe. Unfortunately, this also makes Android a playground for hackers.

Ransomware, spyware, cryptojacking software, surveillance apps, and other malware compromise Android users every single day. Android users also face risks from phishing sites, smishing links, and even pickpockets.

To keep your device safe from all of these threats, you need to have a good Android antivirus with real-time protection, web protection, anti-theft tools, and other additional features. My favorite Android antivirus is Norton, but it’s not free — the mobile app comes with a 14-day free trial, but if you get one of Norton’s multi-device internet security suites, you can use the app for 60 days risk-free.

Question 4

What kind of features can you get with an Android antivirus app?

Accepted Answer

In addition to detecting and removing malware, a free Android antivirus app can:

Keep your personal information private (I recommend Norton Mobile Security).
Ensure you’re connected to a secure Wi-Fi network (Norton can also do this).
Prevent loss or theft of your device (Avira’s free Android app has some particularly effective anti-theft tools).

Most antivirus apps also offer additional paid premium features, and for every free app out there, there are dozens more premium apps. If 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.

Question 5

What are the best free antivirus apps for Android?

Accepted Answer

My top recommendations are Norton Mobile Security (not 100% free, but it has a 60-day money-back guarantee) and TotalAV Mobile Security (good range of free features).

Norton provides excellent antivirus protection along with a number of other useful features, including dark web monitoring (by far the best dark web monitoring of any antivirus app) and a fast VPN with unlimited browsing data, whereas TotalAV has excellent web protection, data breach scanning, and a secure browser.

But there are many great free antivirus apps for Android, all of which either provide strong malware protection, web protection, or additional tools to keep your smartphone or tablet secure.

Question 6

How can I check my Android for viruses for free?

Accepted Answer

You can download a reputable free Android antivirus that includes antivirus scanning, such as Norton or TotalAV (both have excellent malware detection rates). The free Android antivirus apps on this list will also be able to identify and stop a range of internet security threats — most apps come with web protection, so you’ll be warned if you’re about to encounter suspicious or potentially dangerous sites online, including phishing sites that are designed to steal your personal information. But to fully protect your device, you’ll need to ensure the Android antivirus you choose includes real-time virus protection (Norton offers real-time protection).

Question 7

Can Android devices be hacked?

Accepted Answer

Unfortunately, Android devices are more susceptible to being hacked than other mobile devices. Android firmware is designed to be more flexible and customizable compared to alternative firmware versions, such as iOS, but this also opens the door to hackers and malware — it’s much easier to design and distribute malware to Android devices, partly due to flaws in the operating system, and also because Android app stores are often less regulated, especially when compared to Apple’s App Store (which is notorious for its stringent security tests).

To protect yourself against malicious apps, I recommend using Norton Mobile Security. Not only does it have a powerful malware scanner, but it also alerts you to suspicious apps before you download and install them.

Question 8

Can I use a free Android antivirus on a Chromebook?

Accepted Answer

Yes, you can use a free Android antivirus on a Chromebook. Thanks to the Google Play Store access on most Chromebooks, Android antivirus apps like TotalAV can be installed and used for basic protection. They can scan your downloaded apps and files for any potential threats, offering an extra layer of security. However, remember that while they add a level of protection, these free versions may not provide comprehensive coverage against all types of malware or advanced threats.

Question 9

Can a free antivirus detect and remove malware?

Accepted Answer

A free antivirus can detect and remove many types of malware. Apps such as Bitdefender had strong malware detection and removal capabilities in my tests. That said, it’s important to note that while free antivirus apps can provide a decent level of protection, they typically offer fewer features and less comprehensive protection than their paid counterparts. For complete peace of mind, a premium antivirus app is the wiser choice.

Question 10

Does Android have a built-in antivirus?

Accepted Answer

Yes, Android does have a built-in system for detecting and dealing with threats known as Google Play Protect. It scans apps on the Google Play Store for any signs of malware before you download them and periodically checks your device for potentially harmful apps. However, Google Play Protect doesn’t provide the same level of protection as dedicated antivirus apps like Norton. Its malware detection rates are generally lower, and it lacks important features that dedicated apps provide, such as real-time protection, phishing protection, and extra security tools. For these reasons, I’d recommend supplementing it with a reliable antivirus app.
