When a user tries to visit a site that's been blocked by the content filtering settings of Internet Guide, an alert page is shown citing the reason why the page is blocked. When a site is detected as malware or phishing via the Internet Guide's automatic protection, the user is allowed to bypass and continue to the site -- unless that particular site or content category has been explicitly blocked via Internet Guide's settings.
For nonexistent or unresponsive domains, users by default see the Internet Guide showing search results related to the non-working domain with a Google-like look and feel. If you create a free or premium account, you can optionally disable this Internet Guide feature.

FoolDNS provides both free and commercial services, targeted towards home and small business use. It's primarily designed to block online tracking, profiling and advertisements, but also blocks malware and phishing sites.
The premium services include additional functionality and are offered in two different versions. The Audit version adds reporting, logging and the ability to create white- and blacklists. The Business version adds filtering of 2 million unsafe domains, more reporting capabilities and the ability to customize filtering via 20 predefined categories.
When a page is blocked -- for example, if there is malware detected -- a very simple page is shown saying the domain is filtered. No landing page is displayed for nonexistent or unresponsive domains, allowing the Web browser to display its own default error page.

GreenTeam Internet provides both free and premium services for homes and small businesses. Its free preconfigured service automatically blocks malware and phishing sites, advertisements and adult-related content, including aggressive, violent and drug-related sites.
When you create a free account you can customize the content filtering by choosing among three predefined protection levels and 47 predefined categories, and you can create custom whitelists and blacklists. Paid accounts, according to the company, provide "more control, further customization and a wider protection."
When a site is blocked, the user is notified and told which category the site is classified as. On the blocked page, the user can report the page or send an email to GreenTeam asking to unblock it. Users can also enter their email to be notified if the page becomes unblocked. When using a free or premium account, the local network administrator can also include a customized message on the blocked page.
GreenTeam Internet doesn't provide a landing page for nonexistent or unresponsive domains, allowing the Web browser to display its default error page in those instances.
