"register" is what you've named one of your directories.
There must be a link somewhere (from a login form?) that goes
to this URL: http://www.cineweekly.com/index.html/register/
The bots are crawling there from an external link most likely ... from
a search engine. Go to the URL yourself and see what it looks like.
I think it's a page that people should not be able to access?
