Comprehensive security
Bitdefender Mobile Security
Staff pick
Bitdefender stops malware attacks, has a VPN and web protection that warns of dangerous websites before you visit them. This app uses power management to use little of your phone's battery to avoid slow down, and connects to Android smartwatches to help remind you to grab your phone or to locate it if it's left behind.

Anti-hacking

Our final thoughts
Be careful when choosing a mobile security app for your Android because several, especially free apps, don't actually stop virus infections, but rather gather up malware after they've made it to your device. Trojans and ransomware are being manufactured for mobile devices at an alarming rate, so malware blocking on top of virus scans are essential. Phishing filters are also needed since the most common malware are schemes that trick you into giving personal information, including credit card numbers, account passwords, and social security numbers.
Keep in mind that several antivirus apps offer a free version as the initial download with an in-app purchase for the ad-free version.
Our top pick for Android antivirus is because of the quality of protection it gives you on top of being a good value.
