+Theia
+=====
+
+Overview
+--------
+Theia is the worlds first FOSS malware scanner for Android. It is powered by ClamAV signature databases (GPLv3).
+
+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
+- 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
+
+Technical Details
+------------------
+- Signature databases are ClavAV .hdb (MD5 hashes) and .hsb (SHA-1/SHA-256) format
+- Signature databases will not be redownloaded if the file hasn't changed on the server (304 not modified)
+- Realtime scanning powered by recursive FileObserver (Credit: @iNPUTmice)
+- Signatures are stored using HashMaps for O(1) lookup
+- Files have their MD5/SHA-1/SHA-256 hashes calculated in one pass

+- Trove (GPLv3): A memory efficient replacement for Java's Collections
