Hypatia is the worlds first FOSS malware scanner for Android. It is powered by ClamAV style signature databases.
This is a fork of the original (and discontinued) app, which is still looking for maintainers.
Features
- Near zero battery impact: you'll never notice any impact on battery at all
- Extremely fast: it can scan small files (1MB) in 20ms, and even large files (40MB) in 1000ms.
- Memory efficient: with the default databases enabled it uses under 120MB.
- Regular scan: allowing selection of /system, internal storage, external storage, and installed apps
- Realtime scanner: can detect malware in realtime on write/rename in internal storage
- Completely offline: Internet is only used to download signature databases, files will never ever leave your device
- Persistence: will automatically restart on boot/update
- Tiny codebase: coming in at under 1000 sloc, it can be audited by even someone with basic programming experience
- Minimal dependencies: the app only uses libraries when necessary
- Signature databases can be enabled/disabled at the users demand
While you can download the APKs here directly, you should preferably use an F-Droid client so the app stays up-to-date on your device. Some clients have this repo enabled by default, e.g. Neo Store, Droid-ify, or, of course, the IzzyOnDroid client by Sunil. With others (like the official client) you'll have to add this repo manually (see the hint on top of the package list for how to do that).
