Holy mother of whomever....
It is an exploit that attacks any global start templates and injects a redirect code to the site listed. The numbers on the end signify the site to the hacker who adds and removes this code seemingly at will. Large numbers of sites have been hit with this.
I now have a patch in place that should fix this issue.
Please search for a cookie with the name "vbsp" on your machine and delete if present.
I've also edited the title and removed the url to the site it was going to.
Thank you very much for bringing this to my attention.
