Apparently if you click on the link from google, it sometimes takes you to a Thai spam page. Just bookmark the torrent page url directly.
Specifically, use this url with the index.php at the end: http://tracker.tvnihon.com/index.php
For some reason Avast is blocking http://tracker.tvnihon.com/ by itself, so that might mean something?
