I went to your site and it appears one of your many advertisers is hosting some hacked content.

Saw the following happen:
a) one time it wanted me to download a "plug-in" to view ad content (yeah, right)
b) another time it wanted to open a "pop-up" window that contained iframe injector code
c) last time it redirected me to a site, away from yours, that was wired to keep me there

Looked at the source code, it wasn't infected.

I would get rid of a couple of advertisers.
