WCF website hacked

Just a quick post - we have detected that a lot of the files on the WCF website were altered at 04.51 this morning, and finding the site via a Google search yields a malwear warning.  I suggest you do not access the web site for the rest of the day while I re-load it.  In particular, check any link before you click it.  I will post another blog entry when I've fixed it.  Thanks.
