The best mobile antivirus should provide the best malware protection, with low impact on performance. It should also have an easy-to-use interface and offer extras like anti-theft tools including app lock and identity security. Lastly, it should not cost a lot, especially since Android users can install apps from a wider variety of sources than Apple devices (which has strict App Store approvals).
Kaspersky Mobile Antivirus (now called Kaspersky Security and Antivirus) scored perfect marks in independent tests and features a clean and straightforward interface. The free version is free of ads and doesn’t nudge you to upgrade, though it requires a reliable internet connection. A paid plan offers call blocking, Android Wear and a powerful set of anti-theft features. It’s missing some features like a Wi-Fi scanner and privacy tools.
Bitdefender Antivirus Plus is one of the most powerful and feature-rich software available and its protection against malware was top-quality in our tests. It has a simple and clear interface, and its alerts and descriptions are clear and concise. It’s not reliable and requires a constant internet connection to search for viruses.
Lookout Mobile Security was one of the very first antivirus apps available for Android. It is now known as Lookout Security & Antivirus, or Lookout Personal. It is still a favorite choice due to its sleek interface, identity security and low-cost subscription pricing. The free version includes blocking of calls and SMS and device scanning and anti-theft. The premium tier provides real-time protection and a safe web browser.
