Prevent Anonymous users info to be displayed in my views
I think that if a user is showing up in your users table (and thus users view), they must have an account on your system, so they would, at a minimum, be an 'Authenticated' user.  But they probably have no other roles other than 'authenticated'.

So try the following to filter them out of your users view:


Add a filter to your users view

Select the 'User: Roles' filter and configure it as the screenshot below:



Let us know if this worked.

p.s. I'm assuming you have Drupal 7 here, since that's what the screenshots are showing -- Views under Drupal 7, but it really helps to tag your question with the version of Drupal you're running.
