Using "hxxp" is a common method to prevent auto-linking by various email/IM clients and/or forum software to then require the user to actively copy/paste the URL to get the content.

In the case of a security alert, I could see it being used if the destination is in fact an example of an attack site to prevent someone from inadvertently clicking the link and getting infected.
