Nees Help With Malware Code, It's Being Hosted In Posts

I hope this is the right place to do this. I have no where else to turn with the amount of issues this thing has given me. About a month ago my site HellDescent.com was receiving strange malware attacks. False spyware, java activating, and now google has caught wind of it and has flagged my site.

The code is as follows:

[Malware script removed]

Here is the google results page. Idk if you guys can see it, or just me.

I need to get rid of this, traffic is greatly reduced and the site is my hobby as well as my livelihood. I have very important things coming up and can not deal with them if no one is visiting my site. Me and the other guy on the same server have searched every file with no results. We could original find it, but no longer. Do I wait for a wordpress update? Is this a current version flaw? Should I revert to a July backup? I really need help guys.
