Hi,
If you know the category that website belogs to you can use category blocking.
It is very well explained in :

http://www.juniper.net/techpubs/en_US/junos11.4/information-products/topic-collections/security/software-all/security/index.html?topic-62250.html
If you just have the url and block it directly you can use black-lists to block.
It is explained in ;

Example :
To configure integrated Web filtering, create the UTM custom objects first. Custom objects are global parameters for UTM features and apply to all UTM policies where applicable, rather than only to individual policies. In this example, custom URL black and white lists are put into two separate categories.
- Define the custom URL pattern lists--black-list and white-list.
user@host# set security utm custom-objects url-pattern black-list value http://*.**bleep**.com
user@host# set security utm custom-objects url-pattern black-list value http://*.guns.com
user@host# set security utm custom-objects url-pattern black-list value http://*.hacking.com
This would help you.
