Get DAT Updates compares your currently installed virus DAT file against the latest on NAI's FTP server. If there is an updated version, the file may be downloaded and installed. This program started out as a shell script, then morphed into an AppleScript but has now evolved into an AppleScript Studio application. It is free and open source. You may download either the application itself or the entire project including the source code.
Version 1.4 adds the following:
- Added autostart feature so it can run without interaction unless new version can be installed.
