I've looked over the site, and it looks completely legit. The site's being linked to lots of articles about this virus, as they seem to be the only ones who've put together a defensive tool to block it.
The author of the blocking tool has been tweaking and updating it throughout the last couple of days.
That will make it at least a little more likely that the virus writers will write a workaround for this "protection".
Given that most viruses come by being overly trusting I always go by the sniff test, and no matter how you slice their name, either their “preferred” Foolish IT or the website that kind of sounds a lot like “full of crap” they don’t pass my sniff test. Others have solutions out there too, others that don’t smell funny.
