Which one to choose:
The Minimal Download is just the blocklist.
The Expert's Package is the blocklist, an uninstaller, and a few links.
To use it:
If you're using the Minimal Download, just double-click blocklist.reg and let it add the entries into your registry.
If you're using the expert's package, unzip blocklist.zip by:
Xp: Right click, choose Extract All, and choose a place to unzip it.
Other Operating systems: Try an unzipper like 7-zip to unzip it.
Double-click blocklist.reg and let it add the registry entries.
To update (Expert's Package only): Download the latest blocklist and unzip it as before. Double-click blocklist_uninstall.reg and let it add the registry entries, and install the new blocklist as before.
The latest update is listed here underneath the Downloads section. Check back weekly.
