We've updated RSFirewall! with Joomla! 1.5.25 and 1.7.3 hash files as well.
Both, Joomla! 1.5 and 1.7 users are advised to upgrade Joomla! and RSFirewall! to the latest versions and perform a new RSFirewall! "System Check".
The latest revision of RSFirewall! can be downloaded from www.rsjoomla.com, by accessing the "My downloads" area.
