    Android has become one of the most popular mobile operating systems in the world, not surprising considering its great versatility, power, customizability and ease of use.

      Malware Protection for Android

      Android is a great mobile OS because it’s so flexible and open to customization. Its ability to mold to different manufacturers’ needs and the active user community that keeps open source projects alive make it a thriving ecosystem for both users and developers.

      However, this also opens the door for less altruistic users to create malware in much more easily delivered packets—apps themselves. You may be downloading a game and unwittingly install ransomware on your phone, or simply click a mobile link that will install spyware on your device.

      Malware protection, such as the one the best security app for android would provide, will automatically scan and prevent malware from reaching your device before it becomes a problem. It does so in steps, each increasing the level of response.

      Many antivirus apps today include app advisors, which scan apps against databases of whitelisted ones to ensure that you’re not downloading malware and other nasty surprises. This works both ways, as most apps also have blacklists, which in many cases you can add to and customize, that will automatically block you from downloading suspicious apps.

      Once you do download an app, most antivirus tools will automatically scan them to ensure there’s nothing suspicious or hidden in the installation files. This is a crucial step in the process, as most apps seem perfectly harmless when you first download them and may not even trigger the malware until much later.  

      Finally, your antivirus will scan for malware that may have gone unnoticed, scanning your phone system and directories for any suspicious files or applications running in the background.

      How I Test the Best Antivirus Apps for Android

      In a crowded market, it’s difficult to find the right solution for you from the bunch. With similar-sounding features, confusing terms, and sometimes not fully clear information, it can be hard to make the right choice. I am committed to helping you find the best android antivirus for your smartphone, and I do so by running rigorous tests on every app I include on my website.

      To find the best antivirus for Android, I check the following factors:

      How well it performs in scans

      This is the most important job an antivirus has—keeping your phone secure. I run my own tests, adding malicious files to smartphones to see how well they detect and prevent them, and compare them to independent lab results for a better view.

      How little it impacts your phone

      Smartphones are already running hundreds of processes, so your antivirus shouldn’t hinder it further. I test each antivirus on how much it impacts your smartphone to determine the best option.

      How easy it is to use

      Finally, I make sure that even if it’s complex, the antivirus I recommend is easy to use and intuitive enough to let you maximize its potential.
