Smartphones are vulnerable to the same digital threats larger computers face. Surprisingly, the brands that do well in protecting your desktop don’t necessarily protect your phone as well. In this article, we will let you know not only which antiviruses are the best for your mobile phone, but which ones give you a good deal when you buy the package for multiple devices.

Finding the right antivirus for your mobile phone can be difficult, but we’ve tested several options for Android and iOS to help you decide. For the best antivirus specific to your type of mobile phone, see our articles about the best antiviruses for Android and the best antiviruses for the iPhone.

Avast Mobile Security

Platform: Android, iOS

Performance Review

Avast scores very highly in AV-Test for malware protection. It had no false positives and doesn’t considerably affect the phone’s performance or battery life.

Free Features

  • Warns you of malicious or infected apps
  • Trojan protection
  • Anti-spyware
  • Call blocker
  • Power Saver
  • Storage cleaner
  • Firewall
  • Web browser protection against malicious URLs
  • Wi-Fi scanner
  • Secure photograph storage

Paid Features

  • Removing ads
  • Tech support directly from the app
  • App locking
  • SIM card scanning
  • Camera trap (takes a picture with the front camera upon a failed passcode attempt)

AVG Antivirus

Platform: Android

AVG was developed by a subsidiary of Avast and has one of the strongest feature sets of any solution we’ve tried. While it drops the firewall from Avast, it adds anti-theft features.

Performance Review

AVG performs similarly to Avast (that is, strong detection rates and few false positives with little system impact).

Free Features

  • Wi-Fi scanner
  • App locker
  • Storage cleaner
  • Call blocker
  • Photo locker
  • Power Saver
  • Anti-theft phone tracking with Google Maps

A RAM booster is also available, but we highly recommend not using it. In fact, RAM boosters, in general, should be avoided as the operating system is capable enough to handle RAM management by itself.

Paid Features

  • Camera trap
  • Removing ads for other AVG apps

Avira Antivirus Security

Platform: Android, iOS

Performance Review

Detection rates for malware and spyware are excellent, with only one false positive during testing. The app is very light on system performance and battery life.

Free Features

  • Real-time protection
  • Blacklisting
  • External storage device scanning, including SD cards
  • Privacy tracker that warns you whenever a hacker attempts to access confidential information like messages and credit card payment details
  • Anti-theft feature for tracking the phone’s location
  • Phishing protection in web browsers

Paid Features

  • Camera protection
  • More web browser security features

Personally, we don’t believe the Pro version is worth the money.

Bitdefender Antivirus Free

Platform: Android, iOS

Bitdefender is a great, yet simple antivirus without complex configuration or too many features.

Performance Review

The malware detection is good, but the app is great at being lightweight. Scanning is mostly in the cloud, so Bitdefender is fast and has an extremely low impact.

Free Features

  • Real-time protection
  • App scanning

Paid Features

  • Additional anti-malware features
  • Privacy protection
  • Web protection
  • Anti-theft
  • App locker
  • Removing ads

Sophos Mobile Security

Platform: Android, iOS

Sophos has the best free, ad-free solution in the Store. Its user interface, however, looks rather amateurish.

Performance Review

AV-Test has excellent detection rates despite a few false positives.

Free Features

  • Anti-malware
  • Theft protection
  • Ability to wipe all data from the phone via SMS
  • Web filtering
  • App locker
  • App scanner
  • Call blocker
  • Authenticator
  • Wi-Fi scanner
  • External storage scanner
  • Spam blocking

Trend Micro Mobile Security

Platform: Android, iOS

Performance Review

Trend Micro performs consistently well according to AV-Test with no false positives or discernable performance impact.

Free Features        

  • Anti-malware
  • Anti-phishing
  • Privacy features for Facebook
  • Ability to disable all non-essential processes

Once again, ignore the RAM optimizer.

Paid Features

  • Anti-theft
  • App locking
  • Call filtering

Lookout Mobile Security

Platform: Android, iOS

Lookout is pre-installed on some Android devices, particularly those on the T-Mobile network.

Performance Review

Lookout offers decent scanning with reasonable accuracy. There hasn’t been much third-party testing on its performance, but we didn’t notice any slowdowns while using the app.

Free Features

  • Anti-phishing
  • Anti-malware
  • Anti-theft
  • Wi-Fi scanning

Paid Features

  • Identity theft protection and insurance

While certainly unique, the paid option is rather pricey.

MobiShield

Platform: Android, iOS

While MobiShield has an Android port, it’s mostly known for its iOS app’s positive reviews on the App Store. Therefore, that’s where we did the bulk of our testing.

Features

MobiShield runs on a subscription model, and the fee is pretty cheap at only a dollar a month.

  • File encryption (unique to this app, as far as we know)
  • Network monitoring
  • Backing up and recovering contacts
  • Battery, memory, and disk usage monitor

Security Master

Platform: Android

This app is essentially an upgraded version of CM Security, Security Master technically has an iOS port, but it hasn’t been updated since last year and has been downloaded very few times there.

Features

  • Anti-malware and antivirus
  • App locker
  • Message scanner
  • Wi-Fi scanner
  • Storage cleaner
  • Notification cleaner
  • A “CPU Cooler” function to prevent overheating
  • Battery saver
  • Call blocker
  • Camera trap
  • VPN service

There’s also a RAM booster that, again, you shouldn’t use.
