Technical Details
|
|
|
|
|
------------------
|
2019-09-22 21:17:21 -04:00
|
|
|
- Signature databases are ClamAV .hdb (MD5 hashes) and .hsb (SHA-1/SHA-256) format
|
2017-12-26 20:06:14 -05:00
|
|
|
- Signature databases will not be redownloaded if the file hasn't changed on the server (304 not modified)
|
|
|
|
|
- Signatures are stored using HashMaps for O(1) lookup
|
|
|
|
|
- Files have their MD5/SHA-1/SHA-256 hashes calculated in one pass
|
2017-12-26 20:12:35 -05:00
|
|
|
- Realtime scanner is multithreaded and will use half of the device's core count for scanning multiple files asynchronously
|
|
|
|
|
- Realtime scanning powered by a recursive FileObserver
