I think Avast!'s block website feature is great and useful but in my opinion, it should be have default block website feature which user can stick to choose or not. With this feature, Avast! has available a list of blocked websites. Websites which are not for children, porn, and unsafe, etc…, will be added automatically in this list. And the blocked websites list can be up to date by Avast! Automatic Update.

You mean Content Filtering … that is already available for free from OpenDNS ( http://www.opendns.com/ ) and Microsoft Family Safety Center (http://explore.live.com/windows-live-family-safety ) both of which work very well.
