G Data's Internet Security for Android checks all the boxes you'd want in an anti-malware app. It earns top scores in malware detection, it has a broad collection of related security and privacy tools, and it avoids the overexcited you-are-in-so-much-danger nature of many antivirus apps.
Automatically scans new and updated apps: G Data checks any new or updated app you install. You can schedule scan times or initiate manually scans of installed apps or the entire contents of your phone. The app can also automatically check for software and virus-signature updates.
Broad collection of related tools: In addition to checking for malware, the app can help track down -- or lock down -- a lost phone, monitor which permissions you've granted to apps, password-protect apps to guard against unwanted access, and set up parental controls to create a child-safe. You can create white and black lists to filter calls from specific contacts or numbers or set up a separate contacts database to block all communication from a contact.
Top-scoring malware detection: In tests performed by AV-Test -- a security and antivirus testing and research firm -- G Data Internet Security earned perfect scores on Android malware detection.
Annual subscription unlocks it all: The free version is a bit lean -- after a 30-day trial ends, you just get malware detection -- but a $15.99 annual subscription keeps open all the security tools.
Understated approach: With so many security apps visually hollering about how much danger your device MAY ALREADY BE IN!, G Data's understated visual approach is refreshing, with small buttons, clear descriptions, and no overheated alerts.
Interface is a bit flat: The downside of G Data's toned-down approach to visual elements: Screens can look flat and lack hierarchy, making finding what you are looking for a bit of work.
G Data's Internet Security app skips the hysterical nature of its competitors, offering calm top-notch protection for your phone. You need to pay $15.99 a year for all the features, but the calm and steady approach the app takes to warding off malware is worth it.
