How you can block websites, not email file hosts? (C#)
To avoid anything on the computer from going to a website you virtually are tied to either:
- Network Proxy
- Network Driver (like peer guardian's approach, that is essentially packet inspection)

OpenDNS.Com is among an array of ways you can start obstructing sites. See their solutions overview to learn more.
