The Web Blocking List is downloaded by smart protection sources. OfficeScan clients that are subject to web reputation policies do not download the Web Blocking List.

Clients subject to web reputation policies verify a website’s reputation against the Web Blocking List by sending web reputation queries to a smart protection source. The client correlates the reputation data received from the smart protection source with the web reputation policy enforced on the computer. Depending on the policy, the client will either allow or block access to the site.
