Thank you SOOOOO much for your response.
Yes, it is those ads. The footer ad showed up about a week ago, and the just notice another odd thing that we had 128,000 comments (most had been approved which is strange as I didn't approve them). I have now got them all deleted through another plugin...though, that still didn't get rid of those ads.
I used a couple malware plugins:
Anti-Malware from GOTMLS.NET
Sucuri
I've overwritten the plugins from my last back-up.
Thank you so much, wslade, for your help!!!!
