BattleGrip Needs Help

A few days ago I noticed some weird broken code appearing on every page — see the image, below — and then yesterday I was notified by a reader that he couldn’t visit the site because of something called: “Threat Name” Exploit Blackhole Exploit Kit (type 2726)” I have no idea what any of this means, but I cannot have a site running with weird problems like this so I need help. Or I need to delete almost five years of work from the web.

Anyone know what’s wrong and how to fix things?

UPDATE: Justin of generalsjoes.com has stepped in and started making repairs to the site. He found some bad and is carving away and eliminating the problems. Fingers crossed this works!
