Edit: Ok, if you go to the GMD Boston home page, and 'view source' you'll see a nasty little obfuscated piece of javascript down at the bottom of the source. That's what Google is triggering on. I'm going to wager the server your site is hosted on has an SQL server backing it, and it got nailed by a drive by sql injection attack, which puts that string on the bottom of every piece of html it could find.
To translate the script, go here:
HTML & JavaScript Encoder/Decoder
To fix, every piece of html on the site will have to have that removed. If you've got everything backed up locally, just re-upload the site.
