Site Hacked after 3.1.1 update?

I have a site, hotps3games.com, that I updated this morning to the newest wordpress version. I backed up the files first then updated automatically through the dashboard. Several hours later, my site now loads something totally different. Looks like a parking page generated by i.nuseek.com. The picture on the frontpage comes from that site. The source code has a file in it called hotps3games.com.js?? What the heck? The wordpress dashboard and even the cpanel load the same page. Anyone else have this issue?
