Is your phone under attack? Here are top 10 best free Android antiviruses

[dropcap]I[/dropcap]n opposition to the past decade – when our computing activities were restricted to desktops – devices like smartphones and tablets have been at the centre stage at present. The two major operating systems, which come with these devices, are Apple’s IOS and Google’s Android. While Apple’s working software remains exclusive to their devices till date, Google’s operating system supports all the other devices from mobile leaders – be it Samsung or OnePlus.

Now that most of us are dependent on Android, it’s obvious that we would like to protect the operating systems of our mobile devices. However, it has been a popular opinion that Android devices don’t need antivirus until and unless you download apps and softwares from outside the Google ecosystem – that is its official play store. By default, Android does not allow you to install apps from other sources, so there’s no chance of you accidentally installing something nefarious. Supposedly, a dodgy app does find its way into the Google Play market, Google quickly pulls the app and uninstalls it from your device.

However, if you download apps from untrusted sources, your device is most likely to encounter a Trojan attack or other Android viruses. If you still want to wade into the troubling corner of mobile ecosystem, we have listed out the most trusted antiviruses of 2018 for you.
