If, like me, you find Windows Live Messenger’s “Smart Screen” link interception annoying, you can “disable” it.
Just edit your hosts file, and add the following on a new line at the end.
The server at that IP address will just do a regular HTTP Redirection, sending your link on it’s way quick smart. No nanny-net b.s.
PS: This server is run by me, and, technically, I could do bad things like redirecting you to malware. I promise I won’t.
Edit: Oops, got the wrong IP. my bad.
