Short version: it indicates that there are extended attributes for this file, which are not displayed by default.

You can make them visible with

ls -@l

 

or

xattr <filename>

 

The extended attributes can have several purposes, but for example can hold meta data like that the file was downloaded from a certain website, or that certain access rights are allowed or denied ... etc.

I wouldn't recommend doing so, but you can actually clear/remove all the extended attributes:

xattr -c <filename>

 

Or remove just one of them:

xattr -d <attribute> <filename>
