Java popup on site for past 2 days

I am getting this Java popup on my site now for the past 2 days. I am unsure how it got there or how to get rid of it. It is in a foreign language and it basically tells you that you need to update your java. So I did this on one computer, but now I get an alert from eset smart security telling me there is an unknown connection my site is trying to make.
This is really annoying, I don’t believe I am using anything that uses the Java, of coarse I use javascript but I think that is different??
Does anyone know where this could be coming from or how to get rid of it??
