Yeah, we've got the same thing in ours. I thought it was simply because we hadn't updated, but since you're running 7.5.6p2, I can only assume it's not just unpatched versions...
I don't have time to really dig into this for a few hours, but so far in my cursory overview it doesn't look like any of the static files have been altered (at least the mod dates haven't been changed...)
Personally I was hoping to roll back to backup, but it looks like the ads pre-date last night's backup and I don't want to roll back and lose an entire day if possible.
