You must secure your device's mobile phone if it contains sensitive data. Antivirus apps protect you from cybercrimes, hacks and other threats that could expose your data to the risk of falling into the wrong hands with bad intentions. The top Android antivirus apps come with other useful functions such as a WiFi security scanner as well as a privacy guideline and a password manager. The majority of them are free or come with a tier with paid premium features.

Some of these are even freemium, which means they come with a basic version with limited functionality and a premium version that comes with additional security features such as a VPN or password manager. However, it is important to select an antivirus that does not overload your device with unnecessary features and also has a good malware detection.

You should install an antivirus application in addition to Google Play Protect which is integrated into all Android devices. This will shield your device from infection and keep it up-to-date with the most up-to-date security measures. These apps also block attacks that Google Play Protect misses, particularly those that attempt to override Android's security features by stealing permissions.

It's among the most fully-featured antivirus apps available, and has the top malware detection rate during tests by AV-Comparatives.
