Malware ... but where?!.. AHHHH!

That wouldn't do anything anyways. print_output() on that last eval() code disables any further code to be printed.

First of all, I'd suggest you upgrade to at least 3.8.3.

I do not see any suspicious code besides that one in the source, but in Firefox, your style is broken due to the "Reported Attack Site" window. I had to switch to IE8 for viewing your site.
Even in IE8, it doesn't show up. I also used w3 validator.
