Infected

I was reading some doujins here then suddenly I was redirected in chevroletsex.com my domain page was suddendly directed at them at first I thought it was just nothing but whenever I'm reading here it keeps popping and I have to go to the history I can go back where I'm reading can someone please fix this problem.

I believe this issue was coming from the header adzone (the banner at the top of the read online page). I have removed it, please let me know if this issue continues. If it does it means it is coming from one of the other zones.
